How to do a Stamped Overlay
A stamped overlay is a finish that has been embossed with concrete stamps or texture skins to produce different patterns and textures. A stamped overlay is one of the more advanced applications. It has the most authentic look when done correctly. Let’s get into the best way to get that authentic look.
Starting off with a properly prepared concrete surface is important. Once the substrate is ready you will start the application by applying two coats of our concrete bonding agent named Nano Bond. This soaks down into the pores and creates a permanent mechanical and chemical bond.
As soon as the second coat of Nano Bond is dry you will apply a layer of TruHybrid Multi-Mix. This is our polymer, modified cement overlay. The thickness will depend on the depth of the stamping tools.
This layer is applied with a gauge rake. This tool has cams on the ends of a blade that applies the material at the desired thickness that usually ranges from 3/16 of an inch to ½ inch thick.
As soon as you have screeded TruHybrid with the gauge rake, you will smooth the surface with a magic trowel to remove an surface imperfections.Then it is time to wait until the material has begun to set.
This is the most critical part of the stamped overlay. Timing is everything. There is a way to test which is by placing the palm of your hand on the surface and applying pressure. When you can apply slight pressure without the material sticking to your hand; it is time to stamp.
You need to apply a bond breaker to the concrete stamps and surface of TruHybrid to keep the two from sticking together. No Stick is our concrete release agent. Apply to both surfaces by spraying just enough to create a sheen.
Lay your concrete stamp or texture skin on the surface and step onto it. You will lightly walk around flat footed to press the texture into the TruHybrid. As it starts to set you will apply more pressure to get the texture pressed in. If you start with the material a little wet you can just use your hands to press in the texture with the stamps.
