- Fill any voids or gaps with an appropriate filler, such as Polycell Wood Filler, for general repairs.
Application
- Do not apply if rain is expected or if temperatures are likely to drop below 8°C during application or drying. We recommend conducting a test patch to ensure satisfaction with the final appearance.
- Thoroughly stir the product and apply generously and evenly using a synthetic brush or high-quality medium pile roller.
- Allow 4-6 hours drying time between coats; we advise applying two coats for optimal results.
- For the best finish, use Sandtex Rapid Dry Plus Paint in Satin or Gloss as a top coat.
