Silicon is an extremely common element and a material used in semiconductors. Silicon is indispensable in many high-tech products. In waterproofing, there is also a silicone-related coating called silicone waterproof coating. This coating itself is a water-based environmentally friendly waterproof coating made of silicone rubber emulsion and its nanocomposite emulsion as the main base material, and then mixed with inorganic fillers and various additives. Today, the editor of Lunbi is here to introduce you to silicone waterproof coatings.
Main features of silicone waterproof coating
1. The overall film forming property is good. After curing, the silicone waterproof coating will form a continuous, uniform and integrated layer of rubber-like elastomer, so the waterproof layer will have no overlapping joints. It will be better to use it for waterproof construction in special-shaped parts.
2. Good elongation. Because the coating film forms a layer of rubber-like elastomer after curing, it has good elongation and good tensile strength.
3. Rich colors. Silicone waterproof coating is a single-component waterproof coating that can be made into colored coatings.
4. Convenient construction. It can be applied by scraping, coating or brushing. It has no strict requirements on the humidity of the base layer, so it can also be applied on wet surfaces. Silicone waterproof coatings are superior to other waterproof coatings when used at construction sites where open flames are prohibited and complex shapes are prohibited.
5. Green and environmentally friendly. Silicone waterproof coating is non-toxic, odorless, easy and safe to use.
Application scope of silicone waterproof coating
Silicone waterproof coating can be used on new and old roofs, roofs, basements, bathrooms, swimming pools, warehouses, etc. It has good adhesion and permeability to cement mortar, concrete matrix, wood, ceramics and other building materials. It is suitable for basements, Leak repair in toilets and other places has advantages that other waterproof materials cannot match.
Construction method of silicone waterproof coating
1. Grassroots treatment. The base layer must be cleaned and there must be no dirt, open water, etc., and the surface must be smooth without unevenness or sanding.
2. Seam treatment. Before applying silicone waterproof coating, seams or cracks need to be filled with sealing material before subsequent waterproofing can be carried out.
3. Apply scraping coating. The construction of silicone waterproof coating can be done by rolling, scraping, painting, brushing and other methods. Generally, 3-4 scraping coats are required, which is 1-2 coats more than ordinary waterproof materials.
4. Other matters needing attention. The total thickness of the coating film is above 1.5mm, and the interval between each painting is 2-12 hours. This time is determined according to weather conditions and environment. You can add 1-2 layers of fiberglass cloth or other matrix materials in the middle of the paint to achieve better waterproofing effect.
