How Should We Prepare The Wall To Receive The Painting?
If we are going to give a new coat to a room painted in its day with regular paint, no specific preparation is necessary. Now, if what we want is, for example, to cover a humidity, we must correct the cause of it first. What if it’s about giving color to new walls? In that case, it will depend on the support. If we talk about laminated plaster, that is, Pladur, we can apply before painting a primer or a more diluted first layer, according to Loretta. Also, if it is plaster cast to the machine, it is recommended to give a smooth sanding to the walls, and if it is manual – “something more and more improbable,” notes the professional- we can also apply a primer. “It is also essential to take into account if the wall has spots of grease, nicotine, coffee, markers, etc. In these cases,
Hands-on: How and in what order is it painted?
It may seem like a silly question, but for someone who has never done that kind of work, it can be crucial. “The first thing to paint is the ceiling,” the professional assures us, to avoid staining the walls with drops or unexpected brush strokes. And there is more: the areas that we paint with a brush (what is known as “cuts,” according to Loretta) must be carried out before those of the roller. “If we do the wide cut, we do not have to get so close with the roller,” the expert explains.
How to proceed with the walls? To begin with, it is essential to know that they are painted whole and top to bottom: “We should not paint the top part before and then the bottom one, because when the wall dries, you can notice this difference.” Loretta also advises us to use the extension stick to place the roller, an element that, by the way, should be used “with care and tranquility,” because if we make sudden movements, it is most likely that we end up spraying everything.
Another trick? To avoid tearing paint from the ceiling when removing the bodybuilder’s tape -the one that will prevent the color of the wall from slipping where it should not-, we can detach it in “fresh,” that is, while the paint is not yet completely dry. And eye when it comes to diluting the colors: most of the paintings admit this technique, but the proportion marked on the packaging must be respected. “With an excess of dilution, we lose the properties of the paint, and we will have to apply more layers,” warns the professional, who also advises us to always respect drying times before applying a second coat. By the way, something that looks like a drawer is also important, but many times we leave it a little random: cover furniture and floor well. “It’s always easier to cover than to clean,” says Loretta .
Once we have finished, how should we treat the materials before saving them?
How many times have we spent the money on brushes … only to discover that they were unusable when they were stored? To prevent this from happening again, it is vital to treat the rollers and bushes to the water by washing them with water – “better hot than cold,” the expert suggests – and dry them before storing them. On the other hand, if the products we have used to use solvent, the brushes can also be washed with solvent and stored for the next time. “But the rollers are not worth washing, we will spend more solvent than the roller itself costs,” explains the professional – I wish we had known before.
We have already covered practically any doubts you may have regarding the painting of walls, but we still have one more trick that will save you some time: between layers, it is not necessary to wash brushes or rollers. “If we wrap them in a plastic bag, they are kept wet with paint until the next layer,” concludes Loretta.
