High-Gloss Polyurethane Epoxy Top CoatSolvent-Based

HOW TO APPLY? WISEBONDS CLEAR SOLVENT-BASED POLYURETHANE TOP COAT

The versatility as a crack treatment product allows for a relatively wide ranged in application procedures. However, the main focuses of the treatment process remain the same.

Step 1: All cracks should be "dressed" appropriately by cleaning out with a "V" blade or "crack chaser" equipped with an electric grinder.
Step 2: Make sure crack has been cleared of dust and is dry before application of SCT-EP
Step 3: Mix the Concrete Crack Filler thoroughly, until mixture is one consistent color, being careful not to mix more than you need.
Step 4: Prime the "v-joint," or cleaned out the crack, by brushing the epoxy mixture into the crack making sure it is injected into the crack.
Step 5: Combine clean, dry, inorganic silica sand with the epoxy mixture to create a thick slurry.
Step 6: Pour in the mixture and trowel it into the surface. If coming over the top with an overlay, sprinkle some sand over top of the treated crack to help create a better bond with the next coating.
Step 7: After approximately 8 hours. and the product has set, use a grinder to remove any excess materials to maintain a flat, even surface.
