Instant PU Repair | Fast Cure Polyurethane Crack Repair Instant PU Repair is a professional grade, two component polyurethane crack repair system designed for ultra fast curing and rapid return to service. This low viscosity material penetrates deep into the concrete capillaries, essentially "welding" the crack together. It is engineered to be ground and coated in as little as 15 to 20 minutes. This is the go to solution when speed is critical and downtime is not an option for the client. Where This Product Fits in Your System Rapid Prep: Repairing cracks and spalls immediately before grinding and coating. Small Hole Repair: Filling "pop outs" or divots in the concrete slab. Cold Storage Applications: Performing repairs in freezers or cold weather environments where epoxy will not cure. Surface Leveling: Prepping floors for high end epoxy or polyaspartic coatings. Key Advantages Ultra Fast Cure: Ready for diamond grinding in 15 to 20 minutes at room temperature. Superior Penetration: Water like viscosity allows it to reach the bottom of the crack for a structural repair. Extreme Versatility: Can be used on both interior and exterior concrete surfaces. Cold Weather Performance: Maintains a fast cure even in low temperature conditions. High Strength: Once cured, the repair is often stronger than the surrounding concrete. Application and Modification Instant PU Repair is a 1 to 1 mix ratio system that is easy to deploy on the jobsite. For larger repairs or surface leveling, this product can be modified by adding clean, dry silica sand or quartz to increase viscosity and build body. This allows you to create a "slurry" that fills wide cracks or deep spalls without the material running or sinking. Frequently Asked Questions How fast does this product cure?Most repairs are ready to grind flush with the floor in 15 to 20 minutes depending on the ambient and slab temperature. Can I use this in cold temperatures?Yes. This polyurethane system is specifically designed to cure in low temperature environments where standard epoxy repair materials would take hours or days to set. Is this for deep cracks or surface repairs?It works for both. Its low viscosity allows it to penetrate deep hairline cracks, but it can be thickened with sand for surface spalls and larger defects. Can I coat over it with epoxy?Yes. Once the material is cured and ground smooth to remove any surface film, it is fully compatible with epoxy, polyurethane, or polyaspartic coatings. Can I make it thicker?Yes. You can add dry silica sand or quartz to the mixture to increase viscosity for larger repairs or to help level low spots in the slab. Does it have a strong odor?It has a distinct polyurethane odor during the rapid chemical reaction, but it dissipates quickly as the material reaches full cure. Do I need to prime the crack first?No. The low viscosity of the material acts as its own primer, soaking into the concrete for a high strength bond. Can I use this on a wet surface?No. Like most polyurethanes, Instant PU Repair is moisture sensitive during cure. Ensure the crack and concrete are dry before application. What tool should I use to apply it?Small cracks can be filled directly from a pour can. For larger areas, a flat putty knife or steel trowel is ideal for moving the sand slurry into place. Will it change color over time?This product is designed for functional repair rather than aesthetic finishing. It may amber if exposed to direct UV, but since it is typically ground and coated over, this does not affect performance.

LABTEC Thickening Agent | Epoxy Crack and Joint Filler Additive LABTEC Thickening Agent is a professional grade epoxy additive designed to convert liquid epoxy into a smooth, workable paste for crack repair, joint filling, and surface patching. It is easier to mix, cleaner to handle, and more consistent than traditional fillers like Cabosil. ⚠️ COMPATIBILITY WARNING: This product is engineered for use with 100% Solids Epoxy systems ONLY. Do not use with Polyaspartics, Urethanes, or water base epoxies. Using this agent with polyaspartic coatings will trap gases during the fast cure cycle, causing the material to become rubbery and fail to reach proper grinding hardness. This product allows you to turn any 100% solids epoxy into a high performance crack and joint filler on demand. Where This Product Fits in Your System Crack Repair: Thicken your epoxy to a "peanut butter" consistency to fill deep cracks without the material sinking. Joint Filling: Create a non-sag paste for contraction joints and expansion joints. Cove Base: Mix to a heavy consistency to create a radius cove along walls and vertical edges. Surface Patching: Level divots and spalls before your main coating application. How to Use LABTEC Thickening Agent First, mix your Part A and Part B epoxy as directed. Once combined, slowly add the LABTEC Thickening Agent while mixing until your desired consistency is achieved. For Hairline Cracks: Aim for a "Ketchup" consistency. For Deep Cracks & Joints: Aim for a "Peanut Butter" consistency so it stays in place. Pro Tip: For fast cure repairs, mix with 150 Fast Cure Epoxy to create a paste that can be ready for grinding in approximately 90 minutes. Why Installers Prefer LABTEC Low Dust Formula: Cleaner and easier to work with than traditional fumed silica (Cabosil). Smooth Finish: Produces a creamy paste that trowels easily and doesn't "clump." Sands Clean: Once cured, the repair material grinds flat without gumming up your diamonds. Frequently Asked Questions What does a thickening agent do?It turns liquid epoxy into a paste so it can be used for filling cracks, joints, and vertical repairs without sagging or running. Can I use this with Polyaspartic?No. This product is strictly for 100 percent solids epoxy. Polyaspartics release gases during their rapid cure that become trapped by the thickener, resulting in a rubbery, soft material that will not cure properly. Can I use this with any epoxy?It can be mixed with most 100 percent solids epoxy systems, including primers and base coats, to create a repair paste. How thick should I make the mixture?It depends on the repair. Use a thinner mix for hairline cracks so it penetrates, and a thicker mix for joints or vertical coving. Can I sand or grind the repair?Yes. Once the epoxy has cured, the material can be sanded or ground flush with the concrete surface using a diamond grinder. Is this better than Cabosil?Many installers prefer it because it is less airborne (less dust), easier to stir into the resin, and produces a smoother, more manageable paste. Does it change the color of the epoxy?It will turn the epoxy into an opaque, whitish/translucent paste. If you are using a pigmented epoxy, it may slightly lighten the shade. How much do I need per gallon?This varies based on desired thickness, but typically 1 to 2 quarts of agent per gallon of mixed epoxy will achieve a workable patch consistency. Will it affect the cure time of the epoxy?No. The thickening agent is an inert filler and does not change the chemical cure time of the epoxy resin you are using. Can I use this for vertical coving?Yes. By adding more agent, you can create a "stiff" paste that can be molded into a cove radius along the base of walls.

Key Advantages Non Sag Gel Formula: Stays in place on vertical surfaces without dripping or sagging. 100% Solids and No VOC: Solvent free formulation with virtually no odor during application. 1 to 1 Mix Ratio: Simple, equal part mixing for consistency on the jobsite. Superior Bond Strength: High mechanical properties designed for industrial and commercial traffic. Excellent Compatibility: Engineered to be coated over with any epoxy, urethane, or polyaspartic system. Why Professional Installers Use It Unlike liquid repair resins that can disappear into the subgrade or run down a wall, this gel epoxy stays in the "v-groove." This saves you material and labor by eliminating the need for multiple applications. It gives you the time to tool the repair perfectly flush before it sets. Application Guidelines Mixing: Combine Part A and Part B at a 1 to 1 ratio by volume. Mix thoroughly for 3 minutes until a uniform color is achieved. Placement: Use a flat putty knife or steel trowel to press the gel into the crack or spall. Finishing: Tool the material flush with the surrounding concrete. Once cured, the material can be ground or sanded smooth using a diamond grinder. Frequently Asked Questions What makes this different from liquid crack repair? This is a high viscosity gel. While liquid repairs are designed to soak deep into a crack, this gel is designed to bridge gaps and stay in place on vertical surfaces or wide cracks without running. Can I use this on walls? Yes. The non sag formula is specifically engineered for vertical applications like wall stems, curbs, and pillars. How fast can I coat over it? Cure times vary by temperature, but once the material is hard to the touch and ground smooth, it is ready for your primer or base coat. Is this compatible with polyaspartic topcoats? Yes. Being 100 percent solids epoxy, it is a stable base for almost all epoxy and polyaspartic coating systems. Can this be sanded or ground? Yes. Once fully cured, it grinds cleanly without gumming up diamonds, allowing you to create a perfectly seamless transition on the floor. Is it safe for interior residential use? Absolutely. It has zero VOCs and very low odor, making it ideal for basements, garages, and commercial interiors. What is the shelf life? Under normal storage conditions in unopened containers, the shelf life is typically one year. Do I need to prime the crack first? No. This material is designed to bond aggressively to clean, dry, and mechanically profiled concrete without a separate primer. What tool is best for applying this gel? A stiff putty knife, a 6 inch broad knife, or a small steel margin trowel works best for pressing the gel into the repair area. Can I use this for expansion joints? This is a rigid repair material. For moving expansion joints, we recommend a flexible joint filler; however, for static contraction joints, this gel is an excellent choice.
