Water based pre-grout treatment for interior & exterior use For use on all types of textured porcelain tile surfaces. Helps with grout and jointing compound release. On exterior surfaces a further coat can be applied after grouting, which will help with the removal of stains from organic matter Preparation: Ensure surface to be treated is completely clean, dry and free from dirt, grime, cement and grout. If necessary, first wash surfaces with a dilute solution of LTP Grimex 1:5 and white pad. Rinse well to remove residues and leave to dry Application: Shake bottle before use. Before grouting apply evenly to the surface using a broad paint brush, foam roller or light pressure sprayer. Allow to dry for 30 minutes. Apply a second coat. Leave to cure for a minimum of 1 hour before grouting or pointing. Once pointing is dry and all residues have been removed a further coat of protector can be applied covering the joints as well.
