Profile: WDH Sealant Services specializes in offering sealant work to builders. Our types of sealant work includes two part polysulphide gun grade wall joints, high modulas silicone sealant to sanitary ware & tilework and low modulas silicon sealant to windows & doors. High modulas silicone sealant is normally applied to sanitaryware, worktops and tilework. It consists of five stages such as cleaning any dust or dirt away from the area to be sealed, then the sealant is applied in a steady motion making sure to fill the gap, then the area is sprayed with soapy water to prevent any unwanted silicone sticking to the walls/worktop and finally tool the joint with a soapy wooden spatula.
