Gap Crete is the only gray concrete joint sealant cold applied that remains flexible, adheres to jagged concrete joints and edges.  This single component concrete joint sealant is an elastomeric emulsion that flexes and stays in place in large reservoir applications and in extreme temperatures.  Gap Crete is available in large or small containers and can be poured or pumped for large jobs eliminating packaging and waste.   It is NOT A SILICONE OR A URETHANE which is what makes this so unique, but it does meet low modulus silicone caulk standards.  This gray joint sealant for concrete and asphalt is a cold applied single component gray sealant in a ready to use container.  You will enjoy a faster application and drying time for all those concrete crack and joint sealing projects.   -CALL FOR SHIPPING 888-838-7325 (will be billed separately)

Small projects: We recommend using a large industrial caulk gun for our 5 gallon pails to direct the sealant into the joints.  The One gallon pails can be squeezed into place with the directing tip. 

Large projects can be performed using our 55 gallon drums of Gap Crete and the air diaphragm drum applicator (see the link below for our Crack Shot drum Applicator).  Using this method on large scale joint filling projects will achieve the savings you desire with ease of application unlike the other products such as silicone or urethane.  This is where you will save in time on your larger projects while also finding that there is no sealant like this for concrete joint filling in a gray color that holds onto the edges and is nice to work with.

Gap Crete Joint filling will dry and self level.  After curing surface will be recessed approximately 3/8-1/4” below surface but shrinkage is minimal and this product actually holds onto to the crack or joint edges.

“Large Project” applications:   Gap Crete is ideal for larger projects as we can supply this product economically in 55 gallon drums.  This product can be applied with a double diaphragm drum pump (order our Crack Shot Crackfilling Applicator) or install with large reusable industrial sized suringes (eliminates the waste of those small caulk containers).  This allows an efficient application that is less difficult with no need for the expensive RAM pumps.  We carry both the large industrial caulk guns and the double diaphragm drum pumps.  City and municipal feedback has been tremendous.  Applications for large concrete surface areas with joints that have remained exposed and unprotected due to the inefficiency and slow application of silicone caulks and other polyurethane products just became a thing of the past.

Note: Most large 29 oz. caulk containers suggest that the size is ideal for larger projects but when have you ever believed that?!  Any project with size you are left wondering “why isn’t there a better way with less waste”.  We have the answer for your larger joint sealing projects for asphalt and concrete joints and cracks.   If you perform a price comparison you will find a superior performing product and save as much as 25-30% on your next project.

Other Important information or “advantages over traditional Silicone or two component sealants:

Gap Crete dries faster and can be applied and will hold in imperfect conditions or even in moderately damp joints although thorough cleaning is best and moisture increases cure time.  It is flexible and expandable in severe temperature changes.  Gap Crete is NOT A POLYURETHANE AND IS NOT A SILICONE yet conforms to or exceeds specifications for ultra-low modulus silicone for many highway departments and federal agencies.  This gray elastomeric emulsion is good for professionals, government use, homeowners, and commercial building maintenance applications.

Not a Silicone Caulk yet conforms or exceeds specs for ultra-low modulus silicone specifications
