Do Painters Clean Wall Before Painting? Cleaning the walls before painting is still a topic of dispute among professional painters. While some say that washing the walls is crucial, others think that it is not that important.
In this article, we will explain when painters should clean the walls and what do they use for it.
Generally, it is recommended to wash the wall before painting it. It ensures that the wall is perfectly clean and free of dust and other elements that can impede paint from adhering. However, the opinions of the painters vary when It comes to this issue.
Some professionals consider cleaning a necessary point of the painting job. Others, though, encourage cleaning only when the circumstances require it.
A clean wall makes the paint adhere better. Sometimes, though, painters consider that the wall doesn’t need any cleaning. They proceed with painting straight away when the walls are clean enough to ensure a good paint bond.
However, there are situations when skipping washing is a bad idea, as the dirt on it can jeopardize the paint adherence. Here is when cleaning is indispensable:
If the room experiences much traffic, or if it has just gone through a renovation, the walls may be dusty. Even if it dust particles feel tiny, they can still affect the paint bond. In this case, wiping the dust off is a must.
Grease accumulates on walls in the cooking area. Applying the paint on the oily spots is a disaster. That’s why, the painters will always remove the stains first, and then proceed with the painting.
If you have little kids and pets, chances are that the walls are not ready for painting. They may have hand marks, hair, oils, urine that may be an obstacle to the good adherence of the paint. That’s why the painters will want to get a clean wall before they start to paint the wall.
While most of the painters agree on the importance of wall cleaning, they promote different ways of doing it. Still, it always depends on the type of dirt which cleaning method to choose. Here are the most popular ways painters clean the walls:
When the wall doesn’t need much cleaning, the painters will go with just some warm water and a sponge. They will saturate the sponge with the water and run it on the wall to prepare it for painting. They usually use this method when there is nothing on the wall, except dust.
When the wall has dirt and stains, the painters recommend a mixture of lukewarm water and a mild detergent. They damp a sponge or cloth with the soapy solution and wash the wall. They never go with a harsh detergent, because its component chemicals may not interact well with the paint.
TSP is a powder that reacts with water to create a strong alkaline-based cleaning agent. They use this solution to fight tough stains. It may be the grease or wine in the cooking area or the pet waste in the living room.
It will also deal with the hairspray marks in the bathroom at ease. The alkalinity is incredibly good at disintegrating dry dirt and breaking down chemicals. You can also apply TSP on the walls with much skin contact to ensure a clean surface for paint adherence.
Since TSP may not get along with paint, you need to rinse it off the wall as it takes its effect. Use a cloth damp with warm water to remove the solvent residue and make the wall ready for the painting.
To sum up, most painters prefer to clean the wall before painting it. Though, not to waste the time on washing, it’s better to clean the wall only when it’s really dirty. Depending on the stain type, the painters choose to clean the wall in various ways.
It is either a sponge and warm water or a mild detergent or TSP which combats grease and tough stains.
