Primers are most frequently utilized by means of the dipping approach, which entails wholly immersing the components in a very tank of solvent. This is a wonderful system for making use of protecting coatings as it is profitable at completely masking components. A significant-good quality end is often accomplished only if the components are entirely submerged in the solution, Though it's not usually the situation owing to drips that occur if the sections are hung to dry.

For big components, dipping is a nasty Resolution For the reason that tank size turns into prohibitively high-priced. Dipping is most often utilised in producing and upkeep facilities.

On the whole, the dipping paint application method is ideal suited to the following applications:

Factors of a scaled-down size
Preservative layering

Employing Shellac, protect knots.

Distinct shellac or perhaps a white primer that contains shellac may be sprayed on to prevent resinous tree knots from leaking by means of paint or varnish. All-natural resin generated by Southeast Asian lac insect ladies is called "shellac." It truly is great for sealing up tree knots and smells and stains, way too.

Implement a Superior-Develop Primer to Mask Grain

Most spray paints tend to present by way of wood's tough, grainy surfaces, resulting in a textured surface that However appears unfinished.
