Hello, everyone! Could anybody, please, be so kind as to check the following text for mistakes? Thank you in advance! -Surfaces must be completely clean, without dust and totally dry. Sand polish surfaces. -Purge substrate from loose materials (paint not adhered, mold, moss…). In case of mold or moss clean surfaces first with water and bleach, apply fungicide later. -Fix possible damages with Thermal filler. Use mortar to repair the areas with more important flaws. -Check the strength and stability of the substrate with robustness tests. -Apply the product to dusty or absorbing surfaces, allow to dry from 4 to 6 hours.
