When deciding how to paint basement walls, there are several important factors to consider. The basement environment tends to be damp and humid which can cause certain paints to peel or mold. You’ll want to choose a paint that can withstand moisture. The concrete basement walls also require a special primer or coating before painting to help the paint adhere properly. And of course, you’ll want to pick a color and sheen that fits the purpose of the basement space. Taking the time to prepare the walls and select the right basement paint will help ensure it lasts for years to come.
How Dampness Affects Basement Wall Paint
Basements are prone to dampness and humidity thanks to their underground location. Even basements that don’t have obvious water problems can have moisture issues. When water vapor in the air comes into contact with cool concrete walls and flooring, it condenses. This creates higher humidity levels than the rest of the home.
Excess moisture poses a problem for paint on basement walls. When paint captures moisture, it can bubble, peel, crack or encourage mold growth. This destroys the paint’s adhesion and leads to premature failure.
Choosing a basement paint designed for high-humidity environments can prevent this issue. Look for mold- and mildew-resistant paints that specify they are ideal for basements or masonry walls. Latex paints typically withstand moisture better than oil-based paints. Investing in a paint formulated for basements will allow it to last longer.
Using Primer and Masonry Paint on Concrete
In addition to choosing a water-resistant paint, it’s important to start with the right primer and/or base coat. Concrete has a high pH level and is porous. Standard paints will not bond well to untreated concrete walls.
Using a masonry primer or sealer allows the topcoat paint to properly adhere to concrete. Look for a primer specifically made for concrete, masonry and cinder blocks. These seal the surface so paint can’t easily chip or peel.
Some latex basement paints contain additives that help them grip concrete. So you may be able to skip a separate primer. Check the label to see if the paint says it can be used as both a primer and finish coat.
Applying two coats of basement-friendly paint also improves its coverage and durability. This helps it hide any imperfections in concrete blocks for a more uniform appearance.
Choosing a Basement Wall Paint Color
When deciding on a color for basement walls, take into account the purpose of the space. If it will be used as a recreation room or lounge area, brighter colors can help make it feel more cheerful. For a basement workshop or utility area, lighter colors also aid visibility.
Here are some popular color choices for basement walls:
– White or off-white
– Light gray
– Beige/tan
– Light blue
– Soft green
– Cream
Darker paint colors can make a basement feel gloomy and closed-in. Stick with light or medium shades to keep the space feeling open. If you’ll use part of the basement for storage or a workspace, white paint will help illuminate those areas.
You can also opt for an accent wall in a bolder shade. This can add some visual interest without overwhelming the space. Just keep the remaining walls light.
How the Basement Paint Sheen Affects Appearance
Paint comes in a variety of sheens, from flat to high-gloss. The sheen impacts how the painted surface looks and feels. Choosing a sheen is largely an aesthetic choice for basement walls. Here are some things to consider:
– Flat paints have a matte look with minimal reflection. They can help hide wall imperfections.
– Eggshell has a soft velvety finish with slight shine. It also hides imperfections well while offering some durability.
– Satin paints have a low luster. They are easy to clean and resist moisture better than flat finishes.
– Semi-gloss has medium shine. It’s very scrubbable and smooth.
– Gloss finishes have a shiny, slick appearance. They are not ideal for walls since they show flaws.
In basements, many homeowners opt for satin paint for its subtle sheen, easy clean-up, and moisture resistance. Eggshell is also popular to reduce shine while still being somewhat scrubbable. Flat paint works for storage rooms since it touches up well.
Hiring a Professional vs. DIY Basement Painting
You can paint your basement walls yourself or hire a professional painter. Here is an overview of the pros and cons:
Professional Painter
Pros:
– Experienced with prepping concrete and damp basements
– Has right equipment for high ceilings or uneven walls
– Work is faster and often higher quality
– Takes safety precautions on ladders/scaffolding
Cons:
– More expensive than DIY
– Have to schedule work in advance
DIY Painting
Pros:
– Costs much less than hiring a company
– Can be done on your own timeline
– Satisfaction of doing it yourself
Cons:
– Requires more physical effort
– May need to buy or rent equipment
– Mistakes are on you to fix
– Safety risks if inexperienced on ladders
So weigh your specific situation – if your walls require significant repairs or the ceiling is extra high, professional help is best. But for a basic refresh, DIY provides cost savings.
Preparing Basement Walls Before Painting
Proper prep work ensures the basement walls are ready for fresh paint. Here are steps to take before bringing in the paint:
– Repair any cracks or holes with cement patch or caulk. Fill indentations with concrete filler.
– Clean walls to remove dirt, efflorescence, or flaking paint. Use TSP cleaner if walls are greasy.
– Lightly sand glossy painted walls to rough up the surface. Wipe away dust.
– Apply 1-2 coats of primer/sealer formulated for concrete and masonry. Allow to fully dry.
– Use caulk to fill joints or gaps around pipes, corners, and edges. Let dry before painting.
– Cover floors and baseboards with drop cloths to protect from drips and spills.
– Use painter’s tape for clean edges along trim, ceilings and floors. Remove tape immediately after painting.
Proper prep removes possible barriers to good paint adhesion. It also gives the new paint the ideal smooth surface to stick to.
Choosing the Best Paint Finish for Basement Walls
The finish of the paint plays a big role in determining how well it stands up to basement conditions. Here are the most commonly used paint finishes for basements:
Latex Paint
Latex paint is water-based and better suited for damp environments than oil-based paints. Within latex paint, there are different quality levels:
– Economy latex paint – Lower quality but very affordable; may require more coats
– Mid-grade latex – Good durability at moderate price
– Premium latex – Excellent adhesion and durability; ideal for basements
Epoxy Paint
Two-part epoxy paint provides a very hard, protective finish that seals concrete. Use for basements at high risk of moisture problems. More difficult to apply.
Waterproofing Paint
Contains waterproofing additives to create a water-repelling barrier on walls. Use in basements prone to flooding or seepage through foundation walls.
Antimicrobial Paint
Contains agents to inhibit mold, mildew and bacterial growth. Helpful for extremely damp basements. Provide added protection on foundation walls and floors.
When selecting a basement paint, aim for high-quality latex paints rated for basements and masonry. Or use a specialty coating like epoxy or waterproofing paint for at-risk basements. This provides maximum protection.
Tips for Applying Basement Paint
Use these tips for getting the best results when painting basement walls:
– Only paint when humidity levels are below 85% for proper drying. Use a dehumidifier if needed.
– Allow 1-2 days for primer and paint to fully cure between coats.
– Maintain a wet edge when painting to prevent lap marks and uneven sheen.
– Work in sections starting at the top corner and across to other end.
– Use an angled trim brush for cutting in edges and corners neatly.
– Roll paint in “W” or “V” patterns and spread evenly before moving on.
– Apply paint generously to ensure adequate coverage over concrete.
– Work in good ventilation and wear a respirator to minimize inhaling fumes.
Careful prep work, choosing moisture-resistant paints, and properly applying products result in a durable and great-looking paint job.
Average Costs of Painting a Basement
If hiring a professional, costs to paint a basement fall into these typical ranges:
– Small basement (300 sq ft) – $400 to $800
– Medium basement (500 sq ft) – $800 to $1,500
– Large basement (800+ sq ft) – $1,600 to $3,000
This includes primer, two finish coats in a mid-grade latex paint, and labor. Complex prep work, special finishes, or high-end paints can increase the costs.
For DIY painting, costs start at around $100 to $300 depending on the basement size. This covers primer, paint supplies like rollers and trays, paint, and consumables like drop cloths. Labor is free for the DIY route.
Conclusion
