CAN BE APPLIED TO DRY OR DAMP MASONRY: Will fill without shrinking to any depth limit and repair without formwork. Weather resistant, it's also easy to shape. Can be used on all rough masonry surfaces: cement, concrete, breeze blocks, bricks and stones. Overcoat 48-72 hours from application with any standard water-based masonry paint or mineral paint. If using polyurethane or epoxy solvent-based paints, first prime with a water-based exterior paint.

Rock Solid Repair Filler vs. Masonry Repair Filler: Which should I use?
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.
Masonry Repair Filler is very good for deep masonry repairs, can be shaped, and can be applied to damp masonry. You can use it to fill big defects in the substrate and you can also skim with it. It's paintable after 48 to 72 hours.
