I mixed together a couple paint buckets we had at the theatre in order to use them as a primer for the platforms. The reason why we prime the platforms with a base color is to make sure there is no streaks in the paint. This is the platform put together by my fellow work study students for the play Connected.
Using a paving slab weight calculator might help determine how much weight the platform can hold after priming. That’s a smart idea to mix the paints for a base coat! I’m sure it will look great for “Connected.”
