More expensive than your usual silicone, but remember it is an adhesive as well. Does a great job and just a tip to remove excess use soapy washing up liquid on a cloth or your finger.
Having the replaceable tip is very useful to keep it soft.

Steven W 1264 Verified Purchase

Used to reseal / adhere external bottom edge of shower door frame and side panel, which had broken down and gone mouldy. Used CT1 before in applications and been pleased with results, but decided to try BT1. Tooled well and looks very clean - if masking edges then take tape off within 5 minutes, otherwise it will lift edge as it skins up fast. Time will tell

very good product used for bathroom and kitchen lasts a long time

This product works as described and gives a great finish. Although probably the most expensive of the type, well worth it if it survives intact and mould free as suggested in damp environments.

Easy to use

BT1 sealant for bathroom goes on easy - the white is a beautiful bright white & looks great. Time will tell if it stays like that but it certainly looks good now!.

Adam C 1980 Verified Purchase

First time ever used BT1, it's quite similar to CT1 in the way it cures (fast) and also the lack of nasty vinegar smell you get from typical silicone. Used it for a large gap which previously leaked water due to panels movement, heavy duty task.
