Step 4 - Spreading the Squeegee/Bond Coat and 1/4" Stamping Mix
Once the surface preparation, crack repair, joint repair and patching (if needed) is completed, the next step is to apply a Squeegee/Bond Coat Mix and 1/4" Stamping Mix of Ultra Surface® Polymer Concrete. The 1/4" Stamping Mix should be applied in large or small sections at a time depending on the experience of the stamping crew. Usually within one to two hours after spreading it can be stamped to the desired pattern or texture (click here to see patterns and textures available).

Repair cracks and joints. Fill cracks and joints with Epoxy 500 then cover with Elastomeric Basecoat and 4" Fabric. Mark the ends of all joints so they can be sawcut back open the day after stamping. |

Dump the Stamping Mix out of a wheelbarrow onto the wet Squeegee Coat Mix and spread small amounts (135 sq. ft.) at a time so each section is 20 - 30 minutes behind each other.
