Preparation
For the best results, ensure that surfaces to be treated are clean, dry and free of dirt, dust and grease. Do not apply to soft or unsound substrates. Wash down the surface if necessary and allow it to dry thoroughly before application of Prestonett Waterproof Masonry Filler.
Application
Always try a test area before starting any project to assess compatibility of the final finish. Follow the manufacturer's instructions on the tin at all times.
- Use at a dilution rate of 0.25L of water to 1KG of Prestonett Waterproof Masonry Filler, add the powder to the water, gradually, until a workable paste is achieved
- Once paste-consistency is achieved, this product has a working time of around 30 mins, do not use after this point, do not stir the mixture once the hardening process has begun
- Apply with a filler knife or trowel, filling the cavity quickly and carefully
- Drying time depends on average thickness but at around 10mm, the drying time will be approximately 48 hours
- For large cavities, mix filler with a fine grain sand in a ratio of 3 parts filler: 1 part sand, use fibreglass mesh for additional support when rendering thicker than 1.5 cm
- Once dry, a finishing coat of masonry paint is optional
