At AdSeal we manufacture a range of exceptional quality sealers, coatings & impregnators for both EXTERNAL PAVINGand INTERNAL FLOORING. Most paving & flooring will STAIN & FADE unless they are protected. So for natural products - Stone, Slate, Travertine, Terracotta, etc., - or man made products - Block paving, Clay pavers, Imprinted Concrete, Paving flags, etc., - you need a quality sealer/coating to protect & preserve and keep it looking like the day it was installed.
