Master Brand L204511 Interior Primer Sealer 1 Gal White

Product Description

The MASTER BRAND L204511 is a water-based interior primer, sealer, and stainblocker formulated for high-humidity and high-moisture environments. Designed for kitchens, bathrooms, powder rooms, and laundry rooms, this primer delivers strong adhesion to most interior surfaces and creates a solid anchor for topcoats. Its enhanced mildew-resistant film protects the dried primer from mildew growth. Higher solids content improves hide and coverage per gallon. The low-VOC, minimal-odor formula makes it practical for occupied or poorly ventilated interior spaces. Professional painters and general contractors typically apply this product before eggshell, satin, semi-gloss, or high-gloss finish coats.

This primer is suited for residential and light commercial interior applications where surface moisture, steam, or temperature swings are a regular factor. It performs on drywall, plaster, wood, masonry, and most previously painted surfaces, including glossy substrates. The stainblocking capability handles felt marker, grease, ink, pencil, tannin, and water stains before finish painting. One gallon covers typical residential rooms. Topcoat can be applied in as little as one hour after primer application, supporting faster project turnaround.
