Can a qualified Plasterer or Drywall Contractor mix the Paint powder with sand to make a trowel-on interior solid ‘plaster’ wall finish or durable ‘mortar’ for use in rendering exterior walls?
Yes, but they should take care not to use too fine a sand and NO more water than is recommended for the Paint’s use as a paint. Washed concrete sand is recommended and the proportions are usually 1:1 by volume, ie one (1) part by volume the Paint prepared liquid paint to one (1) part by volume of good quality concrete sand. This makes a fine interior trowel applied wall ‘plaster’ with sound absorbing qualities and a thermally insulative ‘render’ for exterior walls. It can also be trowel applied as a 7-10mm thick ultra tough floor or pavement finish. the Paint’s Product Data Sheet PDS on these sand filled and applied finish mixing procedures is available on this website or upon request. It’s best to ‘run some trials’ and test first to ensure the mixture of sand, ‘the Paint’ and water are going to perform to your expectations, ie carefully test first before actual use. Ability recommends to always test first. Trials prior to actual use are essential.
