Fine Surface Filler is suitable for cracks up to 8mm in diameter as long as the surface is not hollow or debonded. Once dry, the filler will present a light tan colour. For a white filler, explore Cornerstone Putty Fine Surface Filler. This dry powder needs clean, potable water added to it to be used as a filler.
The filler will carbonate over time but stay alkaline at the surface for a minimum of 5 weeks. Certain paints, such as mineral or many modern synthetic polymer paints, will be incompatible until carbonation occurs. Painting with a limewash or lime paint should be viable within 1 week.
Consumption rates will change based on the amount and size of the cracks to be filled. On-site trials are advised for the best yield indication for your specific project. Supplied in 1kg and 4kg paper bags.
Do not use in temperatures below 5°C or above 30°C, or if freezing conditions are predicted within the following few weeks, including wind chill. Protect from adverse environmental conditions, including frost, rain, direct sunlight and drying winds.
