Sealants & Adhesives

Silicone Sealant

Sealing round a window or door frame? A good silicone seal keeps rain and draughts out where the frame meets the wall.

We stock Bond It HA6 high modulus RTV marine grade silicone sealant in packs of 3, 4, 5, 10 and 25. You'll also need a silicone gun: see the Xpert dripless caulking gun in our tools.

Before You Seal

Check the surfaces

Check the listing to make sure the sealant suits the surfaces you are sealing.

Clean and dry

Remove old sealant and dirt, and make sure the surfaces are dry and free from grease.

Silicone gun

A dripless silicone gun gives you a steady, even bead.

Pack size

Choose a pack size to suit the job. Larger packs are better value for trade.

Silicone Sealant Guide

How to Apply Silicone

Cut the nozzle at an angle to suit the width of the joint, apply a steady bead in one pass, then tool it smooth before it skins over.

Removing Old Sealant

Cut out the old sealant and clean off what's left with a silicone scraper before you apply new.
