What do we want to accomplish when we’re prepping concrete surfaces?

To have a flawless painting job, you have to make sure that you have a clean, dry, and even surface. Regardless of how clean and smooth your surface is, you still have to apply paint to protect the surface from the effects of water and sun.

If you’re prepping new concrete surfaces, how long does it need to cure before painting?

Allow new concrete to cure for 14-28 days under normal weather conditions before painting.

When repainting, you must check the condition of the old paint first. Which image shows a paint film on concrete that is still in good shape?

The old paint is in good condition if it's still intact and it clings firmly to the surface. If that's the case, you don't have to coat it with a primer. You just have to clean and sand the surface. You may use a rag, mild soap, and water to remove the dust, dirt, grease, or other contaminants. Next, sand the surface to remove bumps. Aside from smoothening out imperfections, sanding also helps in better paint adhesion. Dust off sanding particles and make sure it's dry before you apply the topcoat.

Which image shows peeling paint on a concrete wall?    

If the paint is peeling, the paint film doesn't stick to the surface anymore. If that's happening to your walls, you have to scrape off all the loose and flaking paint. Then, wipe the surface with a damp rag. Let it dry before applying paint.

Which image shows a chalky surface?

To check if your walls are chalky, touch the surface. If there's a loose powdery substance on the surface and it sticks to your hand, that's chalking.

If this is the case, get a clean damp rag or brush to scrub the surface clean. Let the surface dry thoroughly before you start priming. Then, apply BOYSEN Chalk Blocker B-7304 using a brush or roller. The chalk blocker will also serve as your primer.  This premium formula binds chalk residue to the substrate to help maintain its good condition even after months of application. After priming the concrete wall, wait two hours for it dry before applying the topcoat.

Take note that if the chalking is severe, experts recommend that you fully scrape off the paint.

Which image shows a mildew-infested concrete wall?

Your interior walls can have mold or mildew or those dark unsightly patches. They feed on moisture so you will usually find them on bathroom concrete walls, kitchen tiles, or wash areas. If you see them on your wall, you have to treat the surface right away because it will eat the paint away.

Use a bleach solution to get rid of mold or mildew. To make the solution, mix one-part laundry bleach with three parts of water. Use a clean rag or a brush to apply the solution to the surface. Leave it on for 24 hours before rinsing it off. Dry the surface before applying paint.

Which of the following is the correct order of the standard painting system?

We call the proper painting system PPT or prime, putty, topcoat. Start by priming bare surfaces. Then, apply putty to even out minor surface imperfections. Lastly, apply the topcoat.

Note: Some painters prime the surface, apply putty, and then spot prime puttied areas. Finally, they apply the topcoat. That's primer, putty, primer, topcoatthis order is also correct.  Just remember that we always start with the primer and finish with the topcoat.

Why is surface preparation important?

The most common cause of painting problems is inadequate surface preparation. You can avoid painting troubles later on if you take the time to properly prep your concrete surfaces. It will also ensure that you have a long-lasting paint job, which will help you save time and money in the long run.
