Let’s look at what type of respirator would typically be used in a few common painting scenarios.
1. Preparing drywall or latex paint
Any N95 or higher respirator can be used for preparing drywall. However, if you are preparing surfaces that contain lead-based paint, you must use a “100” class particle filter (i.e., N100 or P100).
2. Applying latex paints
A disposable respirator with a carbon layer will help filter out the odor associated with VOCs in paint. For heavier applications of latex paint, consider a reusable respirator with an organic vapor cartridge. If you are spraying, add a particulate prefilter to capture the mist.
3. Working with oil-based paints and stains, solvents and coatings
Consider a half or full facepiece with an organic vapor cartridge and particulate pre-filter.
4. Working with decorative or faux finishes
Faux finishes can include any number of chemical components, so consult the Safety Data Sheet (SDS) for chemical composition to choose a cartridge appropriate for the hazards.
5. Working with asbestos removal or mold remediation
Asbestos has its own substance-specific standard in the OSHA regulations and requires at a minimum a half-facepiece reusable respirator with a “100” class filter. There are no government exposure limits for mold, but the EPA has guidelines for respiratory protection based on the level of contamination.
