During the stamping process, you’ll need to use a liquid release agent to prevent your stamps and tools from sticking to the freshly poured concrete. This prevents you from marring the pattern and helps the concrete hold its set. It also allows you to see the stamping impressions easier.
Liquid release agents are less messy than powder release agents. They also are more environmentally friendly. However, they can leave streak marks. They also must be rinsed off after use.
Powder release agents are not very environmentally friendly. They contain cement, iron oxide pigment, and moisture repellant. They are messy and can get everywhere. They are also not thrown naturally as an aggregate-based color hardener.
Liquid release agents are much easier to use than powder release agents. They can be mixed with powder release agents to give a deeper color. They also can be used on colored concrete. However, liquid releases are more difficult to apply on sloped surfaces.
Powder release agents are not recommended for use on white cement or plywood overlays. The pigment is also not thrown naturally. These release agents can be difficult to remove if you’ve used them for a long time.
The best tool for applying Masters Liquid Release is a spray. It’s also helpful to use a splash brush to apply it. This makes the corners of your pattern look more realistic. You can also add a dark pigment to the release agent to create an antiqued effect.
