Best Sealant For Kitchen Worktops. Our kitchen mastic sealants are manufactured to an exceptionally high standard by the absolute best names in the business such as Dow Corning Geocel Mapei Sika Everbuild Otto-Chemie CT1 Adshead Ratcliffe Arbo and more. Separate pieces of worktop pelmets and upstands can be joined using a worktop sealant which protects against damage caused by water and household detergents.
Dont forget anti fungus or anti mould ability in the sealant favour like Migo good silicon sealant. A fuss-free alternative is a man-made composite material such as quartz or Corian which blend natural minerals with resin to create highly durable surfaces that are non-porous and easy to clean. However these can be costly and require specialist fitting.
So stick to a good make.
Dont just use plastic tile edging please. If you want a really good seal I like Dow Corning its dear but good. I agree with advicce given use black silicone sealant. Worktop adhesives are.
