Cut cartridge tip at 45° angle for desired bead width
Apply with even pressure using standard sealant gun
Create a continuous bead without gaps or air pockets
Tool within 5-10 minutes using a wet spatula or wet finger
Remove excess immediately with BoPin Cleaning Wipes

Joint Design:

Ensure minimum 5mm bead around sanitary fixtures
For corner joints, apply in triangular bead to maximize contact with both surfaces
For larger joints, use backing material to control sealant depth
For optimal mold resistance, ensure complete filling of joint without voids

Limitation

Not suitable for PE, PP, Teflon, and bituminous surfaces
Not recommended for aquariums or continuous water immersion
Cannot be painted (use BoPin MS-240 for paintable applications)
Not for structural glazing or applications with prolonged direct water pressure

Application

For maximum mold resistance, ensure bathroom is well-ventilated
In shower applications, allow 24 hours curing time before exposing to water
Clean sealed areas regularly with mold-resistant cleaner to extend service life
For shower track applications, fill the track completely with sealant for best results
Avoid contact with silicone while wet as it may affect curing process
