FAQs

How long does it take to dry?

Drying time can vary depending on application thickness and environmental conditions, but it typically dries to touch within 15-30 minutes and is ready for recoating after approximately 1-2 hours.

Can I use this on exterior surfaces?

This product is primarily designed for interior use. For exterior applications, consult the manufacturer's recommendations for suitable exterior stain blockers.

What is the best way to ventilate when using?

Always use in a well-ventilated room. Open windows and doors to ensure fresh air circulation. If using in a confined space, consider using a fan to improve airflow.

How do I clean up any spills?

Wipe up any wet product immediately with a cloth. Once dry, it may be difficult to remove. For uncured product, use a suitable solvent like white spirit; for cured product, mechanical removal may be necessary.

Can I paint over it immediately?

It is recommended to wait until the stain block has fully dried and is ready for recoating, typically 1-2 hours, before applying your top coat of paint for best results.

What is the coverage area of one can?

Coverage varies based on the severity of staining and application technique. A general guideline for light staining might be around 1-2 square meters per can.

Troubleshooting

Uneven spray pattern or sputtering

Shake the can more vigorously. Ensure the nozzle is not blocked by clearing it as per instructions after each use and upon completion.

Stain still visible after one coat

Apply a second coat after the first has dried completely. Ensure adequate coverage during application.

Accidental overspray on adjacent surfaces

Mask off surrounding areas with tape and paper before spraying. Wipe away any fresh overspray immediately with a suitable solvent or damp cloth, depending on the surface.

Can does not spray

Check that the nozzle is clear and properly attached. Ensure the can has not been excessively heated or stored improperly.
