Quickly Paint Concrete Blocks With Minimal Mess And Fuss
Concrete blocks can provide an attractive, durable surface for both indoor and outdoor walls. However, plain concrete can also look drab and dreary over time. Painting concrete blocks allows you to add color, transform the look, and protect the masonry surface. But painting concrete can seem like an intimidating task requiring extensive prep work and creating big messes. Follow these tips to quickly paint concrete blocks while minimizing the mess and hassle.
With the right supplies, preparation, and techniques, you can paint concrete block walls efficiently. Careful planning and an organized approach will help the project go smoothly. In a weekend, you can give dull concrete blocks new life with a fresh coat of protective paint.
Gather the Necessary Painting Supplies
Having all the required supplies on hand will make your concrete painting project faster and cleaner. Be sure to get:
- Exterior masonry paint designed for concrete and cinder blocks. Look for acrylic or elastomeric paints that offer good adhesion, durability, and weather resistance.
- Masonry primer and sealer to prepare the concrete for painting.
- Paint rollers with a textured nap as well as angled sash brushes.
- A paint sprayer for quickly covering textured block.
- Painters tape, drop cloths, and tarps to protect surrounding areas.
- Concrete block filler to patch any holes or cracks.
- A wire brush and pressure washer for cleaning.
Thoroughly Prepare the Concrete Surface
Proper surface preparation is crucial for successful, long-lasting paint adhesion. Start by pressure washing the concrete blocks to remove all dirt, dust, mildew and chalking paint. Use a wire brush to scrub off any loose flakes or peeling paint.
Check for cracks, chips, and holes in the blocks and fill these in with concrete block filler compound. Allow this to fully cure before sanding any high spots smooth. Wipe down the entire surface to remove residue before priming.
Apply Primer to the Concrete Blocks
Once the blocks are clean, dry, and repaired, apply a coat of high-quality masonry primer. This specially formulated primer will seal the concrete and help the paint better adhere. Allow the primer to dry completely before painting.
Choose Your Paint Application Method
Select the right technique for applying your concrete paint based on the wall size and block texture. For large flat spans, use a paint roller with an extension pole. This allows you to quickly cover the area. On textured or uneven blocks, a paint sprayer can easily reach into crevices. Use angled sash brushes for corners and edges.
Apply the First Coat of Paint
Before starting to paint, protect nearby surfaces from drips and splatters using tarps and painter's tape. Working in small sections from top to bottom, apply the first coat of paint using your chosen method. Allow time for the paint to fully dry between coats.
Maintain a wet edge as you paint to prevent lap marks. For rollers, work from side to side in approx. 4 foot sections. Overlap strokes and finish in the same direction. With sprayers, keep the tip the same distance from the surface as you work.
Apply a Second Paint Coat for Full Coverage
Once the first coat is dry, spot paint any thin or uneven areas. Then apply the second coat, again working methodically in sections. Allow the recommended drying time before doing any touch-ups or applying additional coats. Proper drying produces a more durable finish.
Optionally Apply a Third Coat
For improved protection and durability, consider applying a third coat of paint to the concrete blocks. Make sure previous coats are fully dry first. The third coat will provide extra coverage for a bolder color and longer-lasting finish.
Clean Up Properly After Painting
Once painting is complete, immediately remove painter's tape before the paint fully dries. Properly clean or dispose of paint brushes, roller covers, and other supplies. Wipe up all spills or splatters. Doing cleanup as you go will minimize the mess at the end.
For long-lasting results, keep your painted concrete blocks looking their best by regularly cleaning with a pressure washer. Avoid using harsh chemicals. Reapply primer/sealer every few years. Address any new cracks or damage right away.
You can paint concrete blocks in a weekend with the right planning. Focus on thorough prep work, an organized painting approach, and proper cleanup to get the job done fast and with minimal mess or hassle. In no time, you'll transform those dreary blocks into an eye-catching focal point.
