A paint stripper is actually a paint remover or a thick gel substance that removes layers of varnish, enamel or glue that has been applied on any surface such as wood, metal, tiles and more.
It’s use is very important when direct access to the original surface of the material is required while preparing any restoration. In other words when we need a clean and smooth surface before applying any kind of new treatment or paint.
But what exactly is the role of the paint strippers?
Surfaces that are old and already painted cannot be repaint directly, as the new layers of paint will not adhere properly. For example, epoxy floor paints or furniture varnishes, so it is necessary to use a paint stripper to remove these layers.
These layers can be removed in two ways, either by sanding the entire surface down, or by applying a paint stripper that removes the layer of paint or varnish.
The stripping method and the type of stripper depend on the actual surface and the layers to be removed.
Types of paint strippers and their applications
Strippers are thick gel substances composed of two different solvents.
One is responsible for soaking into the surface, while the other acts on the topmost layer. By this way we can eliminate all previous applications and have them come on the surface in a wrinkled layer that is very easy to remove, without damaging the structure of the surface.
Removing paint from wood. There is a specific paint stripper that acts on the surface without darkening it or leaving stains or marks. It is important to apply the remover and spread it in the direction of the grain, removing excess product and dry residues so as not to spoil the appearance of the surface.
Removing paint from metal. The procedure here is very similar, but given the strength of the material, it is important to use a spatula or brush to remove all the debris and make the surface uniform.
How to use a paint stripper correctly
If you want to apply a paint stripper effectively, without spoiling the surface, these are the steps to follow:
o Apply the paint stripper with a suitably sized brush depending on the surface. Before application, any excess material must be removed and the stripper should be spread in thick, regular layers.
o Allow the paint stripper to act for 10 to 20 minutes. You will notice a soft film on the surface that can be removed easily with a spatula, scraper or brush.
o Remove all residues best with the help of a brush and water. On some wood or metal materials it may be necessary to add turpentine to the rinse to completely remove all the stripping material.
o Allow the surface to dry for 24-48h before any new treatment.
o Now the surface is ready to be treated, either by applying a new paint, enamel, varnish or protective treatment.
