Mapei Eporip 2kg – Two-Component Epoxy Adhesive for Concrete Construction Joints and Crack Repair

Mapei Eporip 2kg – Professional Two-Component Solvent-Free Epoxy Adhesive

Price: KSh 6,080 Inc. VAT

When a concrete repair or construction joint needs more than ordinary cement mortar, the bonding system matters. Mapei Eporip is a professional two-component, solvent-free epoxy adhesive designed specifically for construction joints, bonding concrete and steel, bonding precast concrete elements, structural reinforcement applications and sealing suitable cracks in cement screeds.

Available from Startcore Ventures in a 2kg kit at KSh 6,080 inclusive of VAT, Eporip provides contractors, engineers, repair specialists and construction professionals in Kenya with a purpose-designed epoxy system for demanding concrete bonding and repair applications.

Unlike a general-purpose adhesive, Eporip is formulated around the requirements of concrete construction and structural bonding. The product consists of pre-measured Component A resin and Component B hardener, which are mixed before application. Once cured, Mapei states that Eporip polymerises without shrinkage, becomes waterproof and develops high mechanical characteristics together with strong bonding capability to concrete and steel.

The supplied Mapei technical data sheet states that Eporip meets the requirements defined by EN 1504-9 and the minimum requirements claimed by EN 1504-4 for structural bonding.

For Kenyan contractors working on concrete repairs, extensions, rehabilitation, industrial floors, structural joints and related construction work, Eporip is therefore best understood as a specialised concrete bonding epoxy, rather than an ordinary adhesive.

What Is Mapei Eporip?

Mapei Eporip is a two-component, solvent-free epoxy adhesive designed for construction and concrete repair applications.

The system consists of:

Component A – Epoxy resin

Component B – Hardener

The two components are supplied in pre-measured quantities and must be mixed together before application.

According to the Mapei technical data sheet, the mixed material has the consistency of a slightly thixotropic paste. This allows Eporip to be applied by brush on both horizontal and vertical surfaces. After curing, the product is described as waterproof, with excellent dielectric properties, high mechanical characteristics and the ability to bond concrete and steel.

This makes Eporip particularly relevant where the objective is not simply to fill a gap, but to establish a strong bonded interface between existing construction materials.

Where Is Mapei Eporip Used?

The Mapei TDS identifies several principal applications for Eporip.

These include:

• Monolithic construction joints between fresh and hardened concrete
• Bonding precast concrete elements
• Bonding steel to concrete
• Filling cracks in concrete
• Construction joints for structural reinforcement of beams and pillars
• Construction joints on decayed industrial flooring
• Rigid, waterproof construction joints
• Reinforcement of beams using the béton plaqué technique
• Sealing cracks in cement screeds

These applications are directly identified by Mapei in the supplied technical documentation.

That application profile is important because Eporip should not simply be marketed as a generic "strong epoxy."

Its value comes from being designed specifically around concrete bonding and construction repair requirements.

1. Bonding Fresh Concrete to Hardened Concrete

One of the key applications for Eporip is creating a bonded construction joint between existing hardened concrete and a subsequent fresh concrete pour.

This can become important when construction takes place in stages.

For example, a contractor may have an existing concrete element and need to extend, repair or connect a new section. The interface between the old and new materials becomes an important consideration.

Eporip is designed to act as the bonding layer between the prepared existing substrate and the subsequent fresh concrete.

The Mapei TDS specifically identifies monolithic construction joints between fresh and hardened concrete as a use for Eporip.

The product can therefore be considered for applications such as:

• Concrete extensions
• Construction joints
• Concrete rehabilitation
• Structural repair interfaces
• Industrial floor repairs
• Concrete element connections

For structural work, however, the design and suitability of the bonding system should always be determined according to the project requirements and applicable engineering specifications.

2. Concrete-to-Concrete Bonding

Concrete repair often involves joining new material to an existing substrate.

The challenge is that the existing concrete surface may contain:

• Cement laitance
• Dust
• Loose material
• Paint
• Form-release oil
• Weak surface layers
• Contamination

A high-performance adhesive cannot compensate for poor substrate preparation.

This is why Mapei's application procedure places significant emphasis on preparing the substrate before Eporip is applied.

The substrate must be clean, solid and strong. Loose and crumbling parts, dust, cement laitance, form-release oils and paint must be removed through appropriate mechanical preparation such as careful sandblasting or brushing.

For Kenyan construction sites, this is especially important when repairing existing buildings, industrial floors, slabs, beams or other concrete surfaces.

3. Bonding Precast Concrete Elements

Eporip can also be used for bonding precast concrete elements.

Precast construction depends heavily on achieving reliable interfaces between manufactured components and other structural or construction elements.

The Mapei TDS specifically identifies bonding precast concrete elements as an application.

The suitability of Eporip should always be assessed against the specific design, substrate condition, required bond line and engineering requirements.

4. Bonding Steel to Concrete

Another important application is bonding steel to concrete.

This can be relevant in construction repair and strengthening work where steel elements need to be bonded to an existing concrete substrate.

Before application to steel, Mapei recommends removing rust and grease residues, preferably through sandblasting to white metal.

This highlights an important principle:

The performance of the epoxy depends heavily on surface preparation.

Eporip should not be applied over loose rust, grease, dust or contaminated steel and expected to deliver its designed performance.

5. Construction Joints for Beams and Pillars

The Mapei TDS identifies Eporip for construction joints associated with the structural reinforcement of beams and pillars.

This places the product within the broader category of professional concrete repair and strengthening materials.

Where a structural element is being repaired or strengthened, Eporip may form part of a broader repair system.

The correct repair specification remains important. Structural work should be assessed by the responsible engineer, and the product should be used in accordance with the applicable design and Mapei technical documentation.

6. Concrete Crack Repair

Eporip can also be used for suitable cracks in concrete and cement screeds.

The application procedure differs depending on crack width.

For cracks wider than 0.5mm, the TDS states that simply placing Eporip is sufficient and recommends spreading sand over the Eporip surface where necessary to favour bonding of a subsequently applied product.

For cracks narrower than 0.5mm, the crack should be widened and thoroughly dusted before repair with Eporip.

This is an important distinction for contractors.

Not every visible crack should automatically be filled with epoxy.

The nature, cause, width and movement of the crack should first be understood.

A structural crack, active moving crack or crack caused by ongoing settlement requires appropriate technical assessment rather than simply applying a surface adhesive.

7. Industrial Floor Construction Joints

Industrial floors experience significant mechanical demands.

Forklifts, machinery, pallet movement, vibration and repeated loading can place considerable stress on joints and repair areas.

Mapei identifies Eporip for construction joints on decayed industrial flooring.

This makes it relevant to:

• Warehouses
• Workshops
• Factories
• Commercial premises
• Industrial floors
• Service areas
• Equipment rooms

Where an industrial floor requires repair, the appropriate preparation and repair system should be selected according to the actual condition and intended service.

8. Rigid and Waterproof Construction Joints

Another application identified by Mapei is the creation of rigid, waterproof construction joints, including examples such as a concrete bed-to-tank-wall connection.

This is useful where a rigid bond is required between concrete elements and the interface also needs resistance to water exposure.

After curing, Mapei describes Eporip as waterproof.

However, Eporip should not automatically be treated as a general waterproofing membrane. Its principal purpose is epoxy bonding and joint treatment, not broad-area waterproofing.

For full waterproofing of concrete structures, Startcore also supplies dedicated Mapei waterproofing systems such as Mapelastic Smart and Mapelastic Foundation.

Eporip Technical Characteristics

Mapei Eporip is designed as a solvent-free epoxy adhesive.

The supplied TDS gives the following key characteristics:

Property Eporip
Product type | Two-component epoxy adhesive
Components | Resin + hardener
Component A | 1.5kg in 2kg kit
Component B | 0.5kg in 2kg kit
Mixing ratio | 3:1
Mixed consistency | Fluid paste
Mixed colour | Grey
Application | Brush or flat trowel
Application temperature | +5°C to +30°C
Complete hardening | 7 days
Workability at +23°C | 60 minutes
Open time at +23°C | 3–4 hours
Storage | 24 months in original packaging
Storage temperature | +5°C to +30°C

The values above are taken from the supplied Mapei technical data sheet and are based on the stated testing conditions.

Eporip Mixing Ratio – 3:1

Correct mixing is critical.

The Mapei TDS specifies a 3:1 mixing ratio of Component A to Component B.

For the 2kg kit, this ratio is already established through the supplied quantities:

• 1.5kg Component A
• 0.5kg Component B

Mapei specifically instructs users to pour Component B into Component A and mix until the material becomes completely smooth and uniform grey.

For small quantities, a trowel can be used.

For larger batches, a drill equipped with a low-speed stirrer can be used.

Importantly, Mapei states that partial quantities should not be used, because incorrect proportions may prevent the product from curing correctly.

Eporip Workability and Open Time

At +23°C, the Mapei TDS gives Eporip a workability time of approximately 60 minutes.

The stated workability changes with temperature:

• +10°C: 90 minutes
• +23°C: 60 minutes
• +30°C: 40 minutes

The open time is stated as:

• +10°C: 5–6 hours
• +23°C: 3–4 hours
• +30°C: 1 hour 30 minutes–2 hours 30 minutes

The application temperature range is +5°C to +30°C. Complete hardening is stated as 7 days.

For Kenyan contractors, temperature should therefore be considered when planning application and subsequent concrete work.

Surface Preparation Before Applying Eporip

Surface preparation is one of the most important parts of any epoxy bonding application.

Before Eporip is applied, the substrate must be:

Clean. Solid. Strong.

Mapei specifically states that loose and crumbling material, dust, cement laitance, form-release oils and paint must be eliminated.

Suitable preparation methods may include mechanical brushing or sandblasting, depending on the substrate and project requirements.

For metal:

1. Remove rust.
2. Remove grease.
3. Prepare the surface appropriately.
4. Where appropriate, sandblast to white metal.

The objective is to expose a sound surface that allows the epoxy to establish proper contact.

Can Eporip Be Applied to Damp Concrete?

Eporip can be applied to dry or slightly damp concrete, according to the Mapei application procedure.

However, the manufacturer specifically states:

Do not use Eporip on wet surfaces.

The substrate may be slightly damp, but it should not be wet.

This distinction matters on Kenyan sites, particularly during rainy periods or when repairing recently washed or water-exposed concrete.

Before application, ensure that standing water and excessive surface moisture have been removed.

Eporip Consumption

Consumption depends on the condition of the substrate and the method of application.

The Mapei TDS gives the following general figures:

Construction joints – rough substrate

Approximately 0.5–0.7kg/m²

Construction joints – very uneven substrate

Approximately 1.0–2.0kg/m²

Sealing cracks

Approximately 1.35kg per litre of cavity

Bonding precast concrete or steel-to-concrete

Approximately 1.35kg/m² per mm of thickness

These are indicative consumption values and actual consumption can vary according to substrate irregularities and application conditions.

This is important when estimating how much Eporip is required for a project.

A contractor should assess the actual surface area, bond-line thickness and substrate condition before placing an order.

Eporip Performance After Curing

Once cured, Eporip develops a range of properties relevant to professional concrete bonding.

According to the supplied Mapei TDS, the product:

• Polymerises without shrinkage
• Becomes waterproof after curing
• Has high mechanical characteristics
• Bonds concrete and steel
• Has excellent dielectric properties

The technical data also reports a 7-day complete hardening time under the stated conditions.

The TDS reports a compressive strength of 70 N/mm² and shear strength of 9 N/mm² for the specified bonded mortar or concrete testing. It also reports concrete-steel bond strength above 3 N/mm², with failure occurring in the concrete in the stated test.

These are manufacturer test values and should not be interpreted as guaranteed field performance in every application.

EN 1504 Compliance

For professional construction and concrete repair work, standards matter.

The supplied Mapei TDS states that Eporip meets the requirements defined by:

EN 1504-9

"Products and systems for the protection and repair of concrete structures."

It also states that Eporip meets the minimum requirements claimed by:

EN 1504-4 – Structural Bonding.

For engineers and contractors, this provides a recognised technical reference when selecting materials for appropriate concrete repair and structural bonding applications.

The exact project specification should always determine whether Eporip is suitable for a particular structural application.

Mapei Eporip vs Mapei Adesilex PG2

Startcore also supplies Mapei Adesilex PG2, another professional Mapei epoxy adhesive for structural bonding.

Adesilex PG2 is supplied as a larger 6kg kit at KSh 9,000 inclusive of VAT and is positioned for structural bonding, reinforcement and concrete repair applications.

The two products belong to the same broad epoxy family but should not simply be treated as identical products.

Eporip

Best positioned for:

• Construction joints
• Fresh-to-hardened concrete bonding
• Precast concrete bonding
• Steel-to-concrete bonding
• Suitable concrete cracks
• Cement screed crack sealing
• Rigid waterproof construction joints

Adesilex PG2

Best positioned for:

• Structural bonding
• Concrete repair
• Reinforcement bonding
• Structural strengthening
• Bonding reinforcement plates
• More extensive structural repair applications

The correct product depends on the actual repair specification and required system.

If the project specifically calls for Eporip, use Eporip rather than substituting another epoxy simply because both products are two-component systems.

Eporip vs Mapegrout T60

Another relevant product in the Startcore range is Mapei Mapegrout T60.

Mapegrout T60 is a 25kg fibre-reinforced, thixotropic structural repair mortar, classified as an EN 1504-3 Class R4 structural mortar, and is currently listed at KSh 3,600 inclusive of VAT.

The key difference is function.

Eporip is an epoxy bonding adhesive.

Mapegrout T60 is a structural repair mortar.

They can therefore be complementary in a concrete repair system.

For example, a repair project may involve:

1. Removing damaged concrete.
2. Preparing the exposed substrate.
3. Treating reinforcement as required.
4. Applying the appropriate bonding system.
5. Rebuilding the damaged concrete with a suitable repair mortar.
6. Finishing and protecting the repaired structure.

The actual repair specification should determine which materials are required.

Eporip vs Chemical Anchors

Startcore also stocks chemical anchoring products such as:

• Akfix C900 Polyester Chemical Anchor
• Akfix C920 Two-Component Injection Mortar
• Sika AnchorFix 1

These products serve a different primary purpose.

Akfix C900 is listed at KSh 2,600 and is positioned for chemical anchoring applications.

Akfix C920 is a two-component injection mortar listed at KSh 2,900, designed for demanding anchoring applications.

Sika AnchorFix 1 is listed at KSh 2,500 for 300ml and is intended for chemical anchoring of threaded rods, rebars and bolts into suitable substrates.

These should not be considered direct replacements for Eporip.

Choose Eporip when the requirement is primarily:

Concrete-to-concrete bonding, construction joints, concrete repair bonding or suitable crack sealing.

Choose a chemical anchor when the requirement is primarily:

Anchoring a threaded rod, rebar, bolt or similar fixing into a drilled hole.

This distinction is important when specifying construction chemicals.

Eporip as Part of a Concrete Repair System

One of the biggest mistakes in construction chemical procurement is choosing products individually without considering the entire repair system.

A concrete repair project can involve several separate requirements.

For example:

Concrete deterioration

→ remove unsound material

Exposed reinforcement

→ assess and treat appropriately

Bonding interface

→ select the appropriate bonding system

Rebuilding

→ use an appropriate repair mortar

Water protection

→ use the appropriate waterproofing/protective system

Structural strengthening

→ specify the appropriate reinforcement and epoxy system

Eporip can form part of this type of professional repair approach where its specified applications match the project.

It should not be treated as a universal substitute for repair mortar, waterproofing membrane, chemical anchor or structural reinforcement system.

Why Professional Contractors Choose Purpose-Built Construction Chemicals

A construction chemical is not simply about whether it "sticks."

The more demanding the application, the more important factors such as:

• Substrate compatibility
• Mixing ratio
• Working time
• Open time
• Cure behaviour
• Shrinkage
• Mechanical performance
• Water resistance
• Temperature limits
• Surface preparation
• Applicable standards

become.

Eporip is specifically documented around these requirements.

That makes it more appropriate for professional concrete bonding work than an ordinary general-purpose adhesive.

Mapei Eporip Application Procedure

A simplified application sequence based on the Mapei TDS is:

Step 1 – Prepare the substrate

Remove loose and crumbling material, dust, cement laitance, paint and form-release oils.

The substrate should be clean, solid and strong.

Step 2 – Prepare metal where applicable

Remove rust and grease.

Mapei recommends sandblasting to white metal where appropriate.

Step 3 – Mix the components

Pour Component B into Component A.

Mix thoroughly until the material is completely smooth and uniform grey.

Step 4 – Apply

Apply using a brush or flat trowel depending on the application.

Eporip can be applied to dry or slightly damp concrete.

Step 5 – Make the subsequent concrete connection

Where Eporip is being used for a construction joint, the subsequent fresh concrete should be placed within the manufacturer's stated open time for the prevailing temperature.

Step 6 – Observe curing requirements

Allow the product to develop its required properties according to the technical documentation.

The stated complete hardening time is seven days under the specified test conditions.

Important Eporip Application Precautions

Mapei provides several specific recommendations.

Do not:

• Apply Eporip below +5°C
• Apply it onto wet surfaces
• Cast fresh concrete onto hardened Eporip
• Apply it over dusty, crumbling or loose surfaces
• Use incorrect component proportions
• Leave mixed product unattended in its container

The manufacturer also warns that the chemical reaction generates considerable heat after mixing and recommends applying the product as soon as possible after mixing.
For professional work, the latest Mapei Technical Data Sheet and Safety Data Sheet should always be consulted before installation.

Cleaning Tools After Eporip Application

Once epoxy has cured, cleaning becomes significantly more difficult.

The Mapei TDS therefore states that tools used for preparing and applying Eporip should be cleaned with appropriate solvents immediately after use.

Contractors should therefore prepare the required cleaning materials before beginning the application.

Do not wait until the epoxy has hardened on tools.

Storage of Mapei Eporip

The product should remain in its original packaging and be stored indoors in a cool, dry location.

The specified storage temperature is:

+5°C to +30°C

The stated shelf life is:

24 months in original packaging.

Proper storage is particularly important for two-component chemical systems because exposure to unsuitable temperatures or poor storage conditions can affect product quality.
