Paint can make walls bright offering fresh and clean palette for more decorating. There are some projects that can be done easier than others. However, in general painting is one of the most cost-effective and easiest projects to enjoy home renovations. Painting concrete rendered walls will improve outdoor and indoor concrete walls. In order to make sure that you enjoy painting this part of your home, you need to carefully follow some steps.
Determine the Materials Used on the Concrete Wall
You must know whether your wall is made of acrylic or cement render. If you have no way to know your wall’s history, you can still figure out the kind being used. Typically, acrylic render looks more like paint than its cement counterpart. Meanwhile, cement render looks more grainy and is likely to be used in a different finishing style to ensure good decorative effects. After you have determined the kind of render, you can continue to the next stop to prepare your walls.
Apply a Sealer Coat
If your rendered concrete wall is made of acrylic, you can apply one coat of sealer. Then let the sealer dry for some hours. When it’s dry, try to feel the finish to know if its smooth or abrasive. When you feel the wall smooth, you don’t need to have a second coat. If you feel it rough, it is a must to apply a second coat of sealer. Let the second coat dry overnight.
Utilize Power Rotary Sander on Walls with Cement Render
Using a clean paintbrush, dust the excess off and apply a coat of sealer. Concrete walls with cement render will have to be applied with 2 or 3 sealer coats. Let each coat dry for some hours.
Use a Brush or Roller in Applying the Concrete Paint
Before you apply the second coat, the first coat must be allowed to dry for some hours. After the application of the second coat and it has gone dry, check the surface to know if you need to do some touch ups on the paint. Areas that have grooves that are not totally sealed are likely to make the paint appear slightly lighter. But you can touch up this by making use of brush with a little amount of paint.
Wash your Outdoor Concrete Walls
You can just use a garden hose in washing the wall. Occasionally, you can wash them with a mild soap and sponge. Indoor walls can be washed by using a damp sponge;however, you don’t have to wash them as frequently as you need to with your outdoor walls.
