What is high build paint?

Answer 1

A high build paint can be sprayed thicker without running or sagging. This is important when you are trying to get better hiding properties. We use a high build paint for our contractor grade paint on new construction houses. From a Glidden web site I saw that their high build paint could be sprayed up to 20 mils thick, whereas from a Diamond-Vogel web site I saw that their non-high build paint could only be sprayed to a thickness of 4 or 5 mils.

Using a high build paint also helps when you are not using a primer because the drywall paper and drywall compound could prematurely suck out the water out of a thinner coat of paint causing the paint to crack or cure improperly.
