How do I prep and paint over a textured sand finish on interior walls in an older Moncton home?

Painting over textured sand finish requires thorough cleaning, careful priming, and the right roller technique to achieve even coverage without flattening the texture. Sand-textured walls were popular in NB homes built in the 1970s-1990s and can look fresh again with proper preparation.

Surface Preparation is Critical

Start by thoroughly cleaning the textured surface with a vacuum using a brush attachment to remove loose sand particles and dust that accumulate in the texture valleys. Follow with TSP (trisodium phosphate) solution or a degreasing cleaner, working in sections with a sponge — avoid scrubbing hard enough to damage the texture. Many older Moncton homes have nicotine staining or kitchen grease embedded in textured walls, which will bleed through new paint without proper cleaning and priming.

Test a small area first by applying your chosen paint to see how it covers. If the existing paint is glossy or semi-gloss, lightly sand the high points of the texture with 220-grit sandpaper to improve adhesion — but don't try to sand the entire textured surface smooth. Fill any holes or damaged areas with spackling compound, then sand smooth once dry.

Primer Selection and Application

Use a high-quality bonding primer like Zinsser Bulls Eye 1-2-3 or Benjamin Moore Fresh Start to ensure proper adhesion over the textured surface. If you're covering dark colours, stains, or switching from oil to latex paint, use a stain-blocking primer. Apply primer with a thick-nap roller (15-20mm/5/8-3/4 inch) to reach into all the texture valleys. Work in 4x4 foot sections, rolling in multiple directions (up-down, then side-to-side) to ensure complete coverage of the irregular surface.

Paint Application Technique

Choose a premium latex paint in eggshell or satin sheen — flat paint can look chalky on textured surfaces, while higher sheens highlight every imperfection. Use the same thick-nap roller you used for primer. Load the roller well but don't oversaturate it. Roll slowly and deliberately, again working in multiple directions to push paint into all the texture valleys. The key is building up coverage gradually rather than trying to cover everything in one heavy coat.

New Brunswick Climate Considerations

Winter is ideal for this project in older Moncton homes since forced-air heating creates low humidity (below 30%) for fast drying and excellent paint flow. Many older homes in the Moncton area lack proper vapour barriers, so watch for any signs of moisture problems like peeling paint or soft spots that might indicate hidden moisture issues — address these before painting.

When to Hire a Professional

Consider hiring a professional if you're dealing with multiple rooms, high ceilings, or if the existing texture is damaged and needs repair. Professional painters have spray equipment that can achieve more even coverage on heavily textured surfaces than rolling, and they can assess whether the texture contains asbestos (common in pre-1980 NB homes) which requires special handling if disturbed.
