  Instructions:
MIXING: Settling may occur in shipping causing a gritty texture that does not stick well. Remix if there is separation in dry mixture. Remove or break up any clumps. Use when temperatures are between 40°F (4°C) and 100°F (38°C). Mix in a clean container with clean water. Use 1 part cool water per 3 parts of powder (for example, 1 cup of water per 3 cups of powder). Add water to powder and mix until Foam Coat turns to a smooth paste. Add more powder or water as needed for your application. A drier mix is stronger. If you add Boost or Bounce, a wet mix is stronger. Do not over mix, or separation can occur. You can add powdered or water based cement pigments while mixing in the wet ingredients. APPLYING: Fill big cracks and holes by applying pasty mixture with a trowel. If using extruded foam (ie Blueboard or Pinkboard) roughen surface with coarse sandpaper. Apply with a paint brush, stucco brush, trowel or hopper gun. Use thinned mixture to texture large areas. For best strength apply at least 1/4” (6mm) thick. Multiple coats may be applied. Brushing or spraying a thin first coat, called a scratch coat, will make the next coat much easier to apply. Try texturing surface as the coating sets. CURE TIME: Working time of 10-20 minutes. Reaches full strength in 12-24 hours, depending on temperature and humidity. Add up to 50% latex paint to the water to extend drying time to 40-50 minutes. FINISHING: Remove dust before painting. This product goes on smooth and can be sanded. Can be used outdoors if sealed with paint. Add Grit texturizer to create a rock-like surface effect. CLEAN-UP: Clean tools and brushes with clean soapy water before coating hardens. If you add Boost, don’t leave any residue as it will be impossible to clean after it dries.   Additional Info

We need to coat the walls of our 800sqft escape room with multiple hidden rooms. All the walls, tree and statues are being coated. How do you suggest we do this.
I usually suggest making the first coat a thin scratch coat with Boost, then getting strength from putting on a thick coating of straight foam coat. Dollar for dollar you will get more strength by doing this. If you need a thinner coat you could go at least 25% thinner with Boost and get the same strength.
It's a good idea to at least use Mesh on any protruding corners and along seams. I made some planter boxes with and without Medium Mesh on the faces and was amazed at how much strength the Mesh added.
