Do you paint a wall for the first time? Is your wall damp and requires a makeover? Does the moisture get inside or outside? We suggest you clarify these questions before you start painting.
With damp walls, you should first investigate the causes. If the moisture is caused by a defective water line, the damage will need to be repaired first.The walls must be properly dry before the coloring can begin. For dry walls we recommend using an internal dispersion.Renovating general damp walls, in particular basement walls, is a little different.For these walls we are using silicate or mineral paints that do not allow new moisture in the room.The room climate is essentially improved by mineral colors.Do you see on the walls any lime color or distemper? If so, they must be washed down with water and brush. The same applies if your walls have a depth primer applied.Once the old color comes off the walls, you need to sand it down until your walls are free from any residual paint. So, the abraded surfaces need to be applied with a depth primer before they can be re-painted.In order to determine whether the floating is fixed, you can tap it gently with a hammer. If the plaster or drywall falls off, then the walls need to be trowelled, re-plastered and treated with depth primer.After a few hours you can start painting.
Preparations and tips for coloring
- Before you start coloring you should mix the paint with a 2 cm wide wooden spatula. Roundwoods are less suitable for this because the color can not mix well.
- Wash new paint rolls in order to remove them from any lint.
- In general, if you paint indoors you should always apply two separate coats.
- The first coat can be diluted with a little water. (Make a sample coat on the wall to see if the mixture fits.)
- For the second coat, paint is usually applied undiluted.
- Use a depth primer only for newly plastered walls. When the old paint peels off, trowel and then apply depth primer.
- If undiluted paint is left over, you can store it for some time in a tightly closed container.
- Look for the expiration date when buying colors. Most indoor paints are 3 years durable. If the color smells unpleasant or if the color is no longer smooth, then you should not use it.
