The bathroom is very humid and easy to grow bacteria. It is easier for the floor tiles to fall off and crack and empty tiles. DBOSS sealant sealant has high bonding strength, and its thermal expansion and contraction phenomenon is not obvious at - 30 ~80 ~C, which is the ideal sealant. Brick cracks are no longer damp, and mildew will not occur naturally, and all kinds of bacteria will lose the hotbed of production sensitivity.
