There are many ways to solve the moldy problem, such as using putty, glass glue and mildew-proof sealant 1, and the sealing performance of putty is very general, which has certain requirements for users' professionalism. For example, after the putty is mixed with water, it should be thoroughly mixed with professional tools without particles. In addition, its construction is inconvenient, inelastic and not environmentally friendly. 2. Ordinary glass glue Ordinary glass glue is a commonly used sealing material in home improvement, but it does not have mildew-proof function. It is more expensive than putty, but much cheaper than mildew-proof glue, and its sealing performance is not very good, only slightly better than putty. In addition, it will corrode the sealing surface, which is not environmentally friendly and pungent. 3. Mouldproof sealant Mouldproof sealant is the most professional sealant used in kitchens and bathrooms at present. Take Sharp brand (neutral) kitchen and bathroom sealant as an example, it has excellent adhesion to ceramic tiles, glazed tiles, metal, rubber, glass and cement walls.

It's just a little expensive, and decoration companies rarely use it to save costs. Owners don't know much about this kind of products. There is no doubt that mildew-proof sealant is the most suitable weapon for owners who have no decoration experience to solve the problem of mildew in their homes. In addition to the slightly higher price, it has absolute advantages in convenience, ease of use, functionality and use effect.
