HOW-TO > PROJECT TIPS > Thompson's® WaterSeal® Clear Multi-Surface Waterproofer
- Do not mix with other waterproofing products; variations in the final appearance may result.
- Do not thin.
- Concrete/Stucco must be completely cured (minimum of thirty days) and dry.
- Shake contents well before use.
- A small trial patch should be tried before application over the entire surface.
- Only one light coat is necessary in most applications.
- Apply by brush, roller, dipping, or sprayer. A garden "pump-up" style sprayer is the simplest method. Product will appear milky white during application, but will dry clear. If puddling of product occurs, remove within 15 minutes by redistributing to dry areas or wiping off.
- Use only with adequate ventilation.
- Darkening of the surface and tackiness will result if over-applied or if overnight temperature falls below 40°F within 48 hours of application.
