ROCK SOLID REPAIR FILLER

We state a drying time of at least 24 hours on all our exterior products to be absolutely sure that they’re ready for the next stage of your process in unpredictable weather. This can of course be quicker in the right conditions.

First of all, make sure that the paint on the base substrate is not a plastic-based coating. This can’t be covered by any filler and needs to be stripped beforehand. Then, after scraping away non-cohesive areas and checking the moisture rate of your substrate, you can apply Rock Solid Repair Filler or Tough Multi-Filler to fill holes, cracks and various gaps. Once your localised filling is dry, you can apply our Exterior Skimcoat or Tough Mukti-Filler as a skim coat (up to 5mm) to achieve a really smooth and even wall. Then, once these filler coats are dry, you can apply your final coat.

For bare masonry (damp or dry) apply Masonry Repair Filler. For all other dry substrates, including glass and glazed tiles, use Rock Solid Repair Filler. Due to the strong properties of Rock Solid Repair Filler, it will need to be shaped and sanded before it sets. Masonry Repair Filler, on the other hand, can be sanded with ease. If you’re looking to paint over the filler, consider that Masonry Repair Filler is cement-based and therefore requires pH levels to drop back before you are able to do so. This will take between 48 and 72 hours. Rock Solid Repair Filler can be painted over in 24 hours, regardless of the depth to which it has been applied.

Our Rock Solid Repair Filler and Tough Multi-Filler are suitable for localised repairs on lime render. For individual application specifications, please refer to the product technical data sheet.
