Troubleshooting
Stain is still visible after drying
Ensure the product was applied in a single, even coat, fully covering the stain. For stubborn stains, a second coat may be necessary after the first has dried. Ensure the original stain was not excessively large for the amount of product used.
Paint not adhering over the sealed area
Ensure the One Coat Damp Seal has fully dried for the recommended 4 hours before applying top coat. Check that the surface was properly prepared and free of dust or grease before application.
Product is too thick to apply
Stir the product thoroughly. If it remains too thick, ensure it has not been stored for an extended period or exposed to extreme temperatures. This product is not designed to be thinned.
Pros and Cons
Pros
- Effectively seals damp stains in one coat.
- Significantly reduces overall decorating time due to fast drying.
- Acts as a primer and stain blocker in a single product.
- Provides a clean white finish, ready for top coats.
- Simple application process.
Cons
- Primarily for sealing damp patches, not general priming.
- Requires surface to be dry enough for application (though designed for damp patches, not soaked surfaces).
- Coverage is specific to the area treated, not general wall painting.
- White finish may require thorough coverage of the stain to avoid bleed-through if not painted over promptly.
Setup, Compatibility & Care
Setup: Ensure the surface area is free from loose paint, dirt, and debris. While the product is designed for damp patches, the surface should not be soaking wet. Open the tin and stir thoroughly before use. Apply directly to the damp stain using a brush.
Compatibility: This product is designed to be painted over with most emulsion paints. It is intended for use on walls and ceilings. It is not suitable for use on surfaces that are constantly wet or subject to heavy condensation.
Care: Store the tin in a cool, dry place away from direct sunlight. Ensure the lid is tightly sealed after use. Clean brushes and equipment immediately after use with water.
