5 tips to avoid finding yourself in this situation!!!
Hello everyone, today I want to address a somewhat peculiar topic, and that is the detachment of paint from the support.
Very often I am faced with this kind of problem and very often I hear that it is not a problem of the support but of the paint used.
Being a paint manufacturer it may seem that I want to defend my category, but I can assure you that in 99.9% of cases it is never the paint’s fault.
Let us first understand why this type of problem occurred.
1) WATER SEEPAGE INTO THE SUBSTRATE
A detachment of paint can occur, for example, when water seeps into the support.
This once penetrated begins the process of evaporation and then passes from the liquid to the gaseous state, creating micro-crystals that by enlarging cause the surface to crack and consequently the detachment of the support and paint.
I always recommend making sure that there is no problem of water seepage, and in case there is, to solve the problem before applying any product.
Another type of detachment of paint from the substrate can be determined by dirt.
In fact, dust, moss, and whatever else create a surface film that does not allow the paint to anchor itself to the surface.
In this case my advice is to carry out a thorough cleaning of the support with a good washing, a good sanding in case there are old paints well anchored, and to remove all those in the process of detachment.
After that, before applying the paint, it is always recommended to apply a good insulator.
I always tell my clients that in any case a coat of Insulant never hurts even if I have to paint a new surface.
Dust is an excellent ally of the peeling phenomenon.
Another reason for this phenomenon that is often underestimated is paint detachment due to incompatibility.
Let me explain further.
We often find ourselves having to repaint surfaces that have already been painted, not knowing what type of product was used previously.
My advice in this case is to sand the substrate using a fine-grit glass paper and after removing the dust created apply a coat of insulation, when dry apply the paint, varnish or enamel you want.
4) DIFFERENT BRANDS
Another case of incompatibility can occur using the primer of one brand and the topcoat of another.
In this case my advice is to always apply primer and topcoat from the same company so by doing so you will be sure not to have any incompatibility problems between the two products.
5) PLASTER DRYING TIME
Detachment of a paint can also occur when the curing time of the plaster has not been respected (it is good practice to always respect the drying time of any product).
In case the problem occurs, remove the layer of paint and all poorly adhering substrates.
When the plaster is completely dry restore the surface with a high-coverage anti-shrinkage filler then apply a coat of insulation and then proceed with the normal painting cycle.
