Dusting after sanding is essential to have proper preparation. On every job, there is always a dedicated dusting brush. Even the smallest touch-up job requires a tool to properly dust and prepare a surface. This is a visually thankless step of the professional painter, but absolutely crucial. Pierre demands that the entire GIDP crew understands the importance of dusting immediately prior to any wet application.

HOW TO DUST
GIDP starts dusting from the top and then they work their way down – which allows gravity to settle the dust into the lower areas. Walls are dusted with a large dusting brush in an energetic, sweeping, downward motion. The surrounding millwork is also dusted aggressively. Once the baseboard and floor is reached, additional care is made to remove the dust from any horizontal surface – maybe even dusted twice. The floor is also dusted out at least 2 feet since painting tools, glaze, and knees are often rested on the floor.
Ideally, the floor should be vacuumed often while dusting, however sometimes a quick dusting of the floor is far easier than hooking up the vacuum. Even if the painter didn’t sand the surface, it must be dusted off prior to beginning the wet application. Even if no dust is visible, as soon as the wet brush slides across the surface, the dust will appear and it will then be too late to fix the problem.
When applying a wet application to a baseboard, oftentimes a jobsite assistant will dust the surface/floor one last time while the glaze is being applied.
THE DUSTING BRUSH
We have brushes that are ONLY for the purpose of dusting. Never use a basecoating brush as a duster and then paint with it. There are a wide array of Dusting Brushes at Pierre’s shop, but the favorite is the big fan duster that looks like a stippler.
It can dust huge walls very efficiently and relieve heavily profiled millwork of pesky dust in seconds. A duster should be made of a fairly coarse hair (bristle or splayed-tip nylon) and loosely packed in the ferrule. If you retire just any brush to become a duster, you may be wasting valuable time using a brush isn’t right for the job.
