A simultaneous cheer and sigh of relief go up when the surroundings are newly painted . Yet, within a couple of years, there come up various paint problems. Well, it does not have to be that way.
The key to ward off different paint problems; is to understand the causes of numerous said failures and then how to fix them. Specific types of problems along with their remedies are listed below.
A very common issue leading to failure of paint is alligatoring . Well it is called so as the cracked paint resembles the skin of an alligator. This issue is caused as the paint is applied in too many layers leading to inner layers loosing elasticity.With a change in temperature the surfaces expand and contract and the brittle paint breaks.
The issue can be resolved by removing the old paint completely by scrapping and sanding. The surface should then be primed with high quality water based primer and painted with top quality exterior water based paint.
This failure arises by moisture getting behind paint, or by painting over damp surfaces. Moisture blisters in paint usually occur when moisture evaporates to form vapor bubble under an impermeable layer of paint , especially on new or oil coatings.
To get rid of blisters first try to remove the source of moisture and then scrap and sand the surface.
This is a white or yellowish usually mineral salt formed on plaster due to moisture migrating through the surface , evaporating , leaving mineral crystals behind. Efflorescense are hygroscopic and will continue to accumulate.
To prevent this issue before using the acidic solution , flood the surface with clean water and then allow the solution to set before scouring off the efflorescence with a stiff brush.
4.Sagging or running
These occur when paint is applied over glossy surfaces ,or due to excessive paint thinning , or paint being applied to a dirty surface or in a weather below recommended temperature
Proper application of paints and surface preparation will help eliminate sags and runs.These sometimes are an indication of an inexperienced painter.
5.Poor stain resistance
This is caused due to use of lower quality paints that are porous in nature and application of paint on unprimed substance.
Prevention of this is possible with the use of higher quality latex paints that contain more binder , that help prevent stains from penetrating the painted surface,allowing easy removal.
Surfactant leaching failures show up if there is an incompatibility between the primer coat and finish coat.
It can be avoided by making sure that the surface to be painted is dry and the surface is not painted in wet weather.
Wrinkles may be caused if paint is applied too thickly , or paint is not brushed out. The best remedy is after scrapping and sanding wipe the affected area with a damp cloth and prim bare areas with appropriate primer and repaint.
So as we have understood various paint problems along with their remedies it can lead to early correction and major reductions in maintenance costs. And hence this issues can be immediately recognized ,modified and result into immediate rectifications.
