This depends on the substrate. But you need to apply as many coats of render as needed to achieve a true and level and smooth sponged surface acceptable for the final surface applied finish and paint coats. Note: keying coats are generally 1 to 3 millimetres thick.  Build levelling coats are generally 5 to 10 [...]

A minimum of 72 hours between these coats in average dry temperatures, however this can be up to 7 days in cold, wet, and wintery conditions, and is obviously weather and render thickness dependant. Render will obviously take longer to dry the thicker it is applied, and the cooler the conditions. Unitex recommends a substrate [...]

Drying times of texture varies enormously depending on weather, wind and the substrate being applied over. There is no simple answer to this question, except to say in most instances of broad wall application the ‘Finisher Applicator’ (2nd or 3rd Applicator) is following closely behind the ‘Texture Applicator’. Customers require a consistent uniform finish and [...]
