Proper paint surface preparation is essential for any paint job. For proper paint surface preparation to take place, considerable knowledge of the surface being painted, as well as the materials to be used, must be known. Also, one has to be willing to take the time to do the job properly. When you are going to paint, many times your main focus is towards the selection of colours, and although that is important, there is an essential previous step, and this is the correct preparation of surfaces. When we prepare the surface that we are going to paint properly, the effort that we will make will last longer, and it will look much better!

Here are some of the essential steps to properly prepare the surface:


For New surfaces

This treatment prevents discolouration, blistering, and peeling of paint over time.

  • Wipe the surface to be worked with a damp cloth.
  • Check that the walls to be painted are clean, dry and free of moisture.
  • Place all the objects towards the centre of the room (or remove them completely) and cover the surfaces that we do not want to paint with a blue canvas or masking tape. Avoid using plastic because it can be slippery.
  • Remove any object that is on the wall, including nails from pictures, lamps and electric plates.
  • Scrape off all loose paint.
  • Sand the surface with sandpaper to correct any irregularities.
  • Wipe the surface again with a damp cloth to remove any remaining sanding particles.

For old surfaces with chalking or chalking

When a surface that has already been painted on other occasions leaves traces of dust, it is called chalking. Preventing it is very easy if before painting a few simple steps are carried out:

  • Scrub the surface thoroughly with soapy water and a stiff-bristled Cerdex brush.
  • If the surface still has poorly adhered old paint, it must be completely removed. For this, if you are in indoors, you can use sandpaper or a spatula. If you are outdoors, you can use a 2500 PSI jet of water. Verify the absence of chalking or chalking on the surface, for this you can take a cloth and wipe it over the surface, checking that it is clean and without the presence of pigments.
  • When finished, rub the wall with a clean cloth to verify the absence of chalking or chalking.
  • Let the surface dry.
  • Using a Cerdex roller or brush, apply a dealer, thus creating the ideal conditions for adhesion of the new paint.
  • Wait 24 hours for the product to dry to give it the final desired finish.

Cracked Surface Preparation

You can remove cracks from a surface by following these simple steps:

  • Wipe the surface to be worked with a damp cloth.
  • Sand the surface with sandpaper to correct any unevenness.
  • Wipe the surface again with a damp cloth to remove sanding residue.
  • Using a spatula, apply a paste
  • Let dry for 4 to 6 hours.
  • To level the surface, sand again until it is completely flat and finally clean the remains.
  • Clean the surface again.
  • Apply any finish of your choice. 
  • Sand gently if the existing paint is shiny, in these cases it is advisable to apply a base that improves the adhesion of the paint
  • Fill cracks, holes and fissures with a putty and allow to dry. Sand excess until the surface is smooth.
  • Remove dust to ensure that the paint has good adhesion.

We know that many times you can’t wait to see the change you are going to make with your new coat of paint, but it is worth spending a little extra time to make your job perfect. We assure you that every second will be worth it!
