KEY BENEFIT HIGHLIGHTS

• Thixotropic Non-Slip Formula: Features zero vertical slip (T classification), allowing heavy, large-format porcelain and ceramic tiles to be laid on walls without sagging or sliding downwards. Eliminates the need for plastic spacers or supporting props during vertical installations.
• Extended Open Time: Gives up to 20 minutes of open time after combing with a trowel, providing ample room to adjust tiles for perfect leveling and straight lines.
• Exceptional Adhesion Strength: Classed as a C2 High-Performance Cementitious Mortar, offering superior structural bond values that far surpass standard field-mixed sand-and-cement screeds.
• Interior & Exterior Versatility: Chemically engineered to resist extreme temperature fluctuations, structural vibration, UV exposure, and moisture ingress, making it perfect for outdoor balconies, wet rooms, kitchens, and exposed facades.
• Shrinkage-Free Curing: Hardens without any structural shrinkage, micro-cracking, or volume loss, ensuring full bedding coverage remains uniform underneath the tile body.
• Eco-Friendly Certified: Features an EMICODE EC1 Plus rating for exceptionally low emissions of volatile organic compounds (VOCs), making it completely safe for green building compliance and confined indoor areas.

CLASSIFICATION & STANDARDS Compliance

Adesilex P7 is thoroughly evaluated and certified according to global building standards, guaranteeing uniform batch-to-batch excellence:

1. EN 12004 Certification: Classified as a C2T mortar.
   • C2: High-performance cementitious adhesive.
   • T: Thixotropic property representing slip resistance on vertical planes.

WHERE TO USE MAPEI ADESILEX P7

MAPEI Adesilex P7 Grey provides dependable bonding over structural substrates across multi-residential developments, industrial complexes, and residential restorations:

Suitable Tile Types

• Porcelain & Vitrified Tiles: Ensures deep mechanical anchoring into low-porosity porcelain tiles.
• Ceramic & Terracotta: Fast moisture transfer for high-retention ceramic installations.
• Mosaics & Glass Tiles: Ideal for pool splashbacks, artistic borders, and complex design layouts.
• Natural Stones: Suitable for medium-weight granite, marble, and slate tiles that are not susceptible to structural warping or water staining.

Approved Substrates (Properly Primed & Cured)

• Cementitious screeds, render coats, and concrete slabs.
• Internal brick walls, blockwork, and lightweight concrete structures.
• Gypsum-based plaster walls and anhydrite screeds (must be thoroughly dried and treated with an appropriate primer like MAPEI Primer G).
• Underfloor heating layouts, provided the heating matrix is fully integrated into the cementitious screed layer.
• Sound, clean cement panels, sound-deadening panels, and wood-cement insulation sheets (spot-bonding installations).

CONSUMPTION AND COVERAGE DATA

Actual consumption rates vary based on substrate flatness, the type of tile being laid, and the specific notched trowel configuration chosen for the project. As a general guide for estimators:

• Mosaics and Small-Format Tiles (using a 4mm square-notched trowel): Approx. 2.0 kg/m².
• Standard Ceramic/Porcelain Tiles (using a 6mm to 8mm square-notched trowel): Approx. 2.5 to 3.0 kg/m².
• Large Format Tiles & Exterior Cladding (using a 10mm notched trowel or round notches): Approx. 4.0 to 5.0 kg/m².
• Spot Bonding of Insulation Panels: Approx. 0.5 to 0.8 kg/m² when applied in points or small dabs, and 1.5 kg/m² for full surface coverage.

Note: For high-traffic areas, outdoor patios, or tiles larger than 30x30 cm, always practice the "double-buttering" method (applying adhesive to both the substrate and the back of the tile) to achieve 100% coverage.

MIXING & APPLICATION STEP-BY-STEP INSTRUCTIONS

To maximize the performance of your MAPEI Adesilex P7 Grey, installation teams should adhere strictly to standard international tile installation practices:

1. Substrate Preparation

• Inspect the installation surface to ensure it is structurally sound, clean, dry, rigid, and completely free from any contaminants like wax, curing agents, release oils, loose plaster, dust, paint, or grease.
• Smooth out major surface unevenness using specific MAPEI leveling mortars prior to adhesive application.
• Gypsum plasters and anhydrite bases must be completely dry (maximum residual moisture below 0.5%), sanded down, and pre-treated with a suitable surface primer to prevent chemical reactions that compromise bond strength.
• Cementitious surfaces exposed to strong direct sunlight in hot environments should be lightly dampened with water to cool them down, ensuring any standing surface water is completely dried before troweling.

2. Preparing the Adhesive Mortar Mixture

• Pour 5.5 to 6.0 Liters of clean, cool drinking water into a clean mixing pail or plastic bucket.
• Slowly introduce the entire 25 kg bag of Adesilex P7 Grey powder while continuously mixing using an electric paddle mixer operating at low speed (~400 RPM).
• Mix thoroughly for 2-3 minutes until a completely homogeneous, smooth, lump-free, creamy paste paste is achieved.
• Slaking Period: Allow the prepared paste mixture to rest (slake) for approximately 2 to 3 minutes. This allows the dry polymers and specialized resins to fully hydrate and activate.
• Stir the paste briefly one more time without adding any more water. The mixture is now active and ready for use, maintaining a pot life of over 8 hours under normal conditions.

3. Applying the Mortar Product

• Apply the prepared Adesilex P7 paste to the substrate using a flat trowel first to form a thin bonding coat, pressing it into the surface pores.
• Immediately follow with a suitable notched trowel to create uniform adhesive ridges. Choose a notch depth that guarantees excellent coverage across the back of your chosen tiles.
• For external tiling projects, heavy commercial floors, large-format tile sizes, or deep-grooved tile backings, apply a thin layer of adhesive directly to the back of the tile ("back-buttering") to guarantee full coverage without voids.

4. Tile Placement and Adjustment

• Do not wet the tiles prior to installation. If the tile backs are exceptionally dusty, wash them briefly in clean water and dry them completely.
• Press the tiles firmly into the fresh adhesive bed using a firm sliding motion to flatten the mortar ridges and maximize contact.
• Check the open time of the applied mortar bed frequently. In normal dry, windy, or hot weather conditions, the open time can decrease to a few minutes. If a dry surface skin forms on the adhesive ridges, do not wet it with water; scrape off the skinned adhesive and spread a fresh layer of mortar.
• Adjust tiles for level and alignment within 30 to 45 minutes after initial placement. Protect freshly tiled areas from heavy rainfall, frost, and intense overhead sun for at least 24 hours.

5. Grouting and Foot Traffic Clean-Up

• Wall Joints: Ready for grouting after 4 to 8 hours using specialized MAPEI grouting compounds.
• Floor Joints: Ready for grouting after 24 hours.
• Foot Traffic: The installation can accept light pedestrian traffic after 24 hours.
• Full Curing: The surface can handle full load weights, traffic stress, or water immersion after 14 days.
• Clean-Up: Wash tools, mixer paddles, and tile faces with clean water while the adhesive remains fresh. Once fully cured, the material must be removed mechanically or with specific acid cleaners.

PACKAGING, STORAGE AND SHELF LIFE

• Packaging: Supplied in robust multi-layer paper bags containing 25 kg net weight.
• Storage Conditions: Keep bags stored off the ground on raised wooden pallets in a cool, dry, sheltered warehouse environment protected from dampness, direct rainfall, and humidity.
• Shelf Life: Under proper dry storage conditions inside its unopened original packaging, the product remains fully stable for a minimum of 12 months from the date of manufacture stamped on the bag.
