Frequently Asked Questions:

Can I paint over it? No, silicone is not paintable. For paintable joints, use acrylic sealant.

How long should I wait before I can shower? We recommend waiting 24 hours for full contact with water.

Is it difficult to apply? No! With a little practice, everyone can do it. You can watch an instructional video online for extra tips.

How many joints can I make with one cartridge? That depends on the width and depth of your joints. On average, you can make several meters of joint with 280ml.

Why is there a minimum joint depth of 6mm? This ensures optimal adhesion and flexibility. The joint depth should be approximately half the joint width.
