805 Pu Foam Multi Purpose 750ml

Genuine Akfix 805 PU Foam Multi Purpose 750ml — Professional Grade Gap Filling and Thermal Insulation

Stop fighting drafts, noise pollution, and energy loss caused by gaps around your windows, doors, and piping. Whether you are a professional contractor sealing a commercial building, an electrician routing conduits through masonry, or a homeowner trying to lower your electricity bill by stopping air leaks, the quality of your sealant determines the longevity of your work. In the Kenyan construction market, there is a dangerous prevalence of "re-filled" or diluted polyurethane foams that look correct when they exit the nozzle but shrink violently or fail to cure within 48 hours.

This is why every unit of Akfix 805 PU Foam sold at Startcore Ventures is 100% genuine and sourced through authorized channels. When you buy from us, you aren't just buying a can of foam; you are buying a guaranteed chemical reaction that expands to the exact volume required, creating a permanent, airtight, and watertight seal. You get the real industrial formula, ensuring your installation doesn't sag, shrink, or leak.

The Akfix 805 PU Foam Multi Purpose is a high-expansion, one-component polyurethane foam designed for the most demanding sealing and insulation tasks. It is engineered to expand rapidly upon application, filling even the most irregular cavities and creating a rigid, closed-cell structure that provides an incredible barrier against heat, cold, and moisture.

The Science of Expansion: Why Akfix 805 is the Professional Choice

Not all expanding foams are created equal. Low-quality foams often have "unstable cells," meaning they expand quickly but then collapse, leaving gaps and creating "thermal bridges" where heat escapes.

The Akfix 805 is formulated for Dimensional Stability. This means:

1. High-Yield Expansion: A single 750ml can provides a surprising amount of coverage because the chemical reaction uses atmospheric moisture to trigger a massive increase in volume.
2. Closed-Cell Technology: Unlike open-cell foams that act like a sponge and absorb water, Akfix 805 creates a closed-cell structure. This makes it an exceptional insulator and prevents water from seeping through the seal into your walls.
3. Rapid Curing: The foam sets quickly, allowing you to trim the excess and paint or plaster over the surface in a fraction of the time required by budget alternatives.

Professional Application Guide: How to Get a Perfect Seal

Expanding foam can be messy if you don't know the professional secrets. To ensure a clean finish and a maximum seal, follow these industry-standard steps:

1. The "Moisture Trigger" (The Pro Tip): Polyurethane foam reacts with moisture to cure. If the air is very dry or the surface is bone-dry, the foam may not expand to its full potential. We recommend lightly misting the gap or the surface with a spray bottle of water before application. This "activates" the chemistry and ensures a denser, more complete expansion.

2. Proper Shaking: The propellant and the PU resin must be perfectly mixed. Shake the can vigorously for at least 30 seconds before use. Failure to shake the can results in "air pockets" and uneven expansion, which compromises the insulation value of the seal.

3. The "Partial Fill" Rule: One of the most common mistakes is filling a gap to the brim. Because Akfix 805 is a high-expansion foam, it will push outward as it cures. Only fill the gap approximately 40% to 60% of the way. The foam will expand to fill the remaining space. Overfilling leads to massive overflows that are difficult to clean and can warp window frames.

4. Trimming and Finishing: Wait for the foam to cure completely (usually 24 hours). Use a sharp utility knife or a serrated saw to trim the excess flush with the wall. Because the foam is now a rigid plastic, it can be sanded, plastered, or painted to match your interior design perfectly.

Material Compatibility and Versatility

The "Multi Purpose" label on Akfix 805 isn't just marketing—it is a versatile tool for multiple trades:

• Windows and Doors: Filling the gap between the frame and the masonry to prevent wind and rain ingress.
• Electrical and Plumbing: Sealing the holes where pipes or cables enter and exit walls to prevent pests (like cockroaches and rodents) and drafts from entering the building.
• HVAC and Air Conditioning: Sealing around AC unit installations to ensure the cooled air stays inside the room.
• Soundproofing: Filling cavities in walls or ceilings to reduce the transmission of noise between rooms.
• General Attachment: Bonding lightweight panels or insulating boards to walls where a wide-area bond is needed.

Complete Your Project: Recommended With This Product

To achieve a professional-grade installation, the foam is only one part of the equation. We recommend pairing your Akfix 805 with these essential items from our catalog:

1. PU Foam Cleaner: Polyurethane foam is incredibly sticky and almost impossible to remove once cured. We stock professional-grade PU cleaners that remove uncured foam from tools and surfaces instantly.
2. Professional Utility Knives & Blades: For a clean, flush trim of your cured foam, you need a razor-sharp blade. Using a dull knife will tear the foam and leave a jagged, unprofessional edge.
3. Sika Waterproofing Systems: If you are using PU foam to seal a bathroom or kitchen window, pair it with Sika’s waterproofing membranes to ensure that no moisture penetrates the structural wall.
4. Acrylic Sealants: After trimming the PU foam flush, apply a thin bead of acrylic sealant over the joint before painting. This creates a "belt and braces" approach—the foam provides the insulation, and the sealant provides the final aesthetic and weather-proof skin.

Frequently Asked Questions (FAQ)

Is this Akfix 805 PU Foam genuine? Yes. Every can sold at Startcore Ventures is 100% genuine Akfix. Be wary of suspiciously cheap foams in the market; these are often diluted or use inferior chemicals that shrink over time, leaving your walls vulnerable to drafts and leaks.

Can I use this foam in the rain? The foam is moisture-curing, so it works well in humid conditions. However, you should not apply it during a heavy downpour, as excessive water can interfere with the chemical reaction and cause the foam to collapse or bubble.

Will this foam attract pests or rodents? On the contrary, when applied correctly and trimmed flush, Akfix 805 is one of the best ways to stop pests. It creates a solid, rigid barrier that mice and insects cannot easily chew through or crawl through.

How long does it take for Akfix 805 to fully cure? The foam will feel "tacky" and set within a few minutes, but the full chemical cure takes approximately 24 hours. We recommend waiting a full day before trimming the foam or applying paint/plaster.

How is this different from a spray-foam insulation kit? The Akfix 805 is a "one-component" foam, meaning it is ready to use straight from the can. Professional spray-foam kits are "two-component" systems used for entire walls. Akfix 805 is the gold standard for gaps, joints, and targeted insulation.

What should I do if I get the foam on my skin? If the foam is still wet, use a PU foam cleaner or a cloth soaked in acetone. Once the foam has cured (hardened), it cannot be dissolved; you must gently peel it off or use a pumice stone/scrubber to remove it.
