In the context of painting of new woodwork, which of the following is the process of sealing the knots by suitable means so that the resin from the knots may not destroy the paint film by way of cracking, peeling or brown discoloration? 

Concept:

When painting new woodwork, it is important to treat the knots in the wood to prevent resin from seeping out and damaging the paint film. This treatment is known as knotting. Knotting involves sealing the knots with a special solution to prevent the resin from causing issues such as cracking, peeling, or brown discoloration of the paint film.

Additional Information

• Stopping: This process involves filling small holes, cracks, and other imperfections in the wood to create a smooth surface before painting. It does not specifically address sealing knots.
• Priming: This involves applying a primer coat to the entire surface of the wood to create a uniform base for the paint. Priming helps with adhesion and coverage but does not specifically seal knots.
• Finishing: This refers to the final coat of paint or varnish applied to the woodwork. It is the last step in the painting process and does not involve sealing knots.
