Application

Any substrate must be thoroughly cleaned, free from dust, loose material, surface contamination and materials which reduce adhesion or prevent suction, or wetting by repair materials. De-laminated, weak, damaged and deteriorated substrates, and where necessary sound substrates, must be removed by suitable preparation equipment. Follow appropriate instructions on the product data sheet for each specific substrate and application method.

Finishing for all types of application must be carried out to the required surface texture using suitable finishing tools as soon as the mortar has started to stiffen.

Curing

Protect fresh mortar immediately from premature drying using an appropriate curing method, e.g. curing compound, moist geotextile membrane, polythene sheet, etc. Curing compounds must not be used when they could adversely affect subsequently applied products and systems.
