For Outdoor Living
🧱 High-Performance Fireplace Block Adhesive
The only adhesive with the strength, long-term durability, and heat resistance to truly excel in outdoor fireplace construction.
✅ Ideal For:
- Anchoring natural or fabricated stone, brick, tile, or block
- Building outdoor firepits and fireplaces
🔥 Product Features:
- 100% solids – will not shrink
- Engineered for high-temperature environments
- Delivers lasting performance in outdoor conditions
Packaged in a standard caulking cartridge (requires a caulking gun, not included).
The adhesive is light gray in color, offering a clean, professional appearance when applied.
- Prepare the Cartridge: Cut the tip of the nozzle to your desired bead size (¼” recommended) and break the foil seal inside the cartridge before applying.
- Apply the Adhesive: Dispense in a continuous bead along the surface where bonding is required.
- Set and Secure: Position materials in place while the adhesive is still tacky. Adhesion begins during the curing process and continues to strengthen over 7 days.
Application Tips
- Cut the nozzle tip slightly wider than usual for easier, smoother application.
- Ideal application temperature: 60°F–100°F (16°C–38°C).
- Can be applied to wet surfaces — mist the area lightly with water (H₂O) to accelerate curing and increase bond strength.
- Suitable for vertical or overhead applications without sagging or troweling (non-slump formula).
- Coverage: A ¼” bead provides approximately 26 linear feet per cartridge.
- Clean-Up: Use rubbing alcohol before the product cures.
- Strength:
- Delivers over 50 PSI or 3,000 lbs per linear foot of bond area.
- Offers instant green strength, capable of holding 17 lbs or more of dead weight before fully cured — requiring minimal support.
- Temperature Resistance: Once cured, withstands extreme conditions from –40°F to 300°F.
- Not Recommended For:
- Adhering firebrick inside outdoor fireplaces (due to 300°F max limit)
- Use on porcelain, aluminum, steel, marble, granite, fiberglass/glass, or most woods
- Storage: Do not store below 32°F.
- Formula:
- 100% solids, contains no solvents
- Suitable for wet substrate application, unlike silicone, polyurethane, or latex adhesives
- A one-part moisture-cure hybrid polymer that remains flexible, forming a durable, long-term rubber bond
- Non-shrinking formula reduces material usage by up to 50% or more
