Five Mistakes to Avoid When Painting Concrete

Here is the list of mistakes to be avoided when painting on concrete walls and ceilings.

Painting your own home by yourself is a wonderful idea to save money and to choose which color you mostly prefer for the walls. However, doing this huge job by yourself can also be prone to failures which might make you spend more money than you intended to and make your home uglier than before. So before you dip your paintbrush and start painting, here are the top five mistakes to avoid when painting concrete.

1. Not Cleaning the Surface First

Clean your concrete walls and ceiling first for any cobwebs, dust or crayon marks that might have been there on a very long time. If you skip the cleaning process and paint your concrete walls, it will result to a dirty, dull and bleeding coat that is unpleasant to bear.

2. Not Removing Paint or Wallpapers First

If you are planning to coat the old concrete paint or wallpaper with fresh paint, then you will surely heading for a disaster. This process will surely make the new paint coat peel off, swell or show off uneven spots in a short duration of time. Better use a scraper or a putty knife at the corners and scrape the old paint and wallpaper to prepare the concrete for the new paint coat.

3. Not Putting Primer First

Primer is the main bonding material for the paint and the concrete; it works just like glue or tape. Without it the paint will not stick for long on the walls which result to early peeling, so make sure that all concrete areas are covered in primer before painting.

4. Not Painting on the Right Temperature

Painting your concrete walls or ceilings in a very hot temperature could cause the paint to dry quickly and not stick on the concrete surface. Painting in a cold temperature could cause the paint to dry slowly which could attract pollen, dust and insects to stick to the wall. It is best to paint between the temperatures of 40 ºC to 90 ºC for oil-based paints and 50 ºC to 90 ºC for latex paints.

5. Not Buying Enough Paint

It is a very bad habit to buy a can of paint after you ran out of paint to use because it would cause uneven lines on the concrete. The best thing to do is to determine how much paint you would need for your project. A gallon of paint can coat 400 square feet of concrete; so better get the total square feet of the concrete to be painted then divide by 400 to get the number of gallons to be used.

Remember to avoid these five mistakes when painting concrete and you will definitely have a long lasting and beautiful home.
