What type of sealing compound is recommended for preparing odor-damaged surfaces for painting?

The best choice for preparing odor-damaged surfaces for painting is the non-porous sealing compound. This type of sealing compound is designed to create a barrier that effectively blocks odors from penetrating through the surface materials. Non-porous sealants are particularly beneficial in environments where odor contamination has occurred, as they limit the ability of odor-causing substances to escape and helps to ensure that any lingering scents are trapped beneath the surface.

In contrast, water-soluble sealing compounds may not provide the same level of odor control, as they can be more permeable to odors. Oil-based sealing compounds can also be effective, but they may not be as preferable for certain surfaces or odor situations compared to non-porous options. Quick-dry sealing compounds focus on drying time rather than odor-blocking capability, which is the primary concern when treating odor-damaged surfaces for painting.

Thus, non-porous sealing compounds are generally recommended for their ability to effectively seal surfaces and prevent odors from affecting the newly applied paint.
