Frequently Asked Questions (FAQs)

Q: Can this paint be used as a final topcoat?
A: While it provides a clean, matt finish, it is primarily designed as a base coat to block stains. For best results and a uniform decorative finish, it should be overcoated with your choice of interior emulsion.

Q: How many coats are necessary to block a stain?
A: In most cases, one coat is sufficient to block common household stains. For more persistent or heavily discoloured areas, a second coat may be applied once the first is dry.

Q: How long should I wait before applying a topcoat?
A: Allow the product to dry completely (typically a few hours depending on temperature and humidity) before applying a finishing coat.

Q: What types of stains can this paint cover?
A: It effectively covers stains from water damage, smoke, nicotine, pen marks, crayon, and grease.
