painting your walls?
WHAT TO KNOW BEFORE YOU PAINT
Refreshing your interior walls and ceilings with a new coat of paint is the easiest way to update a room. Get professional results when you paint by identifying your walls’ interior surfaces, selecting the best products for the job, and maintaining your hard work. Consider this your primer for all-things interior.
A paint’s performance is directly related to the degree of surface prep. Before you pick up a paint brush, make sure your walls’ surfaces are:
- Sound – check for structural defects. Are there cracks? Any loose pieces of the wall? Some of these might be easy fixes, but if you are unsure or issues re-emerge contact a licensed general contractor.
- Clean – the surface must be free of all dirt, dust, wax, oil, grease, and chalk.
- Dry – make sure to follow the manufacturer’s instructions for any caulking or spackling you used for the amount of time required before painting. Also make sure you allowed adequate time for the surface to fully dry after cleaning.

- What it is: Lath and plaster is a building process that begins with narrow strips of wood nailed horizontally across wall studs or ceiling joists. Plaster is then applied to fill the gaps and smoothed creating the wall surface.
- Where it’s seen: Interior walls and ceilings in homes built until the late 1950s.
- Before you paint it: New plaster must cure for at least 30 days at 72°F (22°C) before applying paint. Make sure walls have been sanded, smoothed and dusted. Fill cracks with spackling compound, allow to dry and sand smooth. Remove sanding dust.
- Recommended products: Our new OmniPrep - Universal Interior Primer is perfect for new plaster since it is highly resistant to alkalinity. Apply your favorite Diamond Vogel interior latex finish.
- What it is: A panel of gypsum plaster covered on both sides by paper. Drywall is easier, faster, and less expensive than plaster, and became the predominant wall building material in the United States after the 1950s.
- Where it’s seen: New construction, renovation, and repair work.
- Before you paint it: Fill nail holes and imperfections with spackling compound and allow to dry. Sand tape joints and spackled areas and remove dust. Glossy surfaces should be dulled by sanding.

Once you’ve cleaned, prepped, and painted your surface, you’ll want to maintain your walls’ integrity. Try these go-to tips for keeping your walls spic and span.
Deal with dirt: Interior paint typically gets dirty in many situations: hand prints around switches and knobs; splashes in kitchen and bathrooms; marks on hallways and corridors; “soot” accumulating above electric lamps and other heat sources.
Removing dirt before it accumulates not only improves appearance, it reduces chances of it getting permanently embedded in the paint film. While changing color is a good reason for painting, covering over dirty paint is generally not. Especially when these easy tips will keep your paint looking great.
- Check for dirt periodically and assume it will be present in and near cooking areas (airborne cooking oil) and at all places at hand height.
- Always try to clean the surface first with a slightly dampened (with water) clean white cloth. You can add a mild, non-sudsing cleaning agent if necessary. Harsher cleaners should only be used when necessary, recognizing that alkaline cleaners can dull the sheen or gloss of satin, semi-gloss and gloss products.
- Washed surfaces should be rinsed thoroughly because residual cleaner can interfere with adhesion of paint applied later.
Treat mildew: Watch for growth of mildew on painted surfaces that tend to be moist; this includes laundry and basement areas, bathrooms and kitchens. Mildew should be treated and removed and never simply painted over.
- Apply a 3:1 mixture of water and household bleach to the mildewed area using a rag or sponge. Wear eye and skin protection and a respirator. With colored paints, test a small area first to be sure the bleach solution won’t cause fading. Protect the floor and nearby articles.
- Don’t allow the bleach solution to dry on the surface.
- Rinse area thoroughly.
