Sealant Gun/Caulking Gun

A sealant or caulking gun is your one-stop fix to any leakage and gaps that might occur over the course of the years. These standard sealant guns compress the inside of the tube, pushing out your silicone applicators onto the frame of your shed at a controllable pace. 

Silicone Sealant

As a sealant silicone is long-lasting and waterproof. The skeleton gun is standardised to hold many types of sealants. Simply pop in your tube of caulk and get to work!

Frame, Roof, and Window Application 

Silicone works on metal surfaces as well as plastic and wooden sheds - so you can use this sealant with ease on any BillyOh building. With the skeleton sealant holder and heavy-duty caulking tube, you can work on a variety of carpentry projects with simple-to-use caulking tools that don't require any construction experience.
