## Description

Everbuild Foam Sealant Joint Backer Rod 20mm x 10 Metre : desertcart.co.uk: DIY & Tools

Review: Good product - I had 2 sets and have almost finished them, v useful; sturdy and easy to fill cracks , definitely value for money
Review: Easy to use and stops draughts - Great little idea, and bought in two different sizes to seal under skirting boards. Top tip - if you have a newish house or extension, then frequently the plasterboard has been dot and dabbed against the brickwork but not sealed effectively. This was the case for us and lots of cold air was seeping in, so the two new rooms would cool down far quicker than the existing build. Effectively it didn't matter how well insulated the new build was, the draughts bypassed it. The Everseal backer rod can be squeezed into place and suddenly the cold air stops. I like it as it's not permanent - if I need to change something later on I can take it out (unlike say sealant or the expanding foam). And one further point - if you've got leaky skirting boards, check the light switches and fittings - we had clear draughts from both and bought a 70p car sponge from Wilko, cut it up and squeezed into the holes in the plasterboard - again it made an instant difference.

## Features

- SIZE: 20mm diameter round foam rod, 10 metre length – this is a large size for wide joints. Measure your gap before ordering.
- CHOOSING THE RIGHT SIZE: Pick a backer rod slightly wider than the gap (about 25% wider). This 20mm rod suits joints of roughly 15-16mm; for narrower joints choose the 10mm or 15mm size.
- WHAT IT DOES: Pushed into a joint before sealing, it controls sealant depth, saves sealant and stops three-sided adhesion so the joint can move.
- SOFT FLEXIBLE FOAM: Compressible foam that squeezes into the joint and holds in place while you apply sealant over it.
- WHAT YOU GET: 1 x 20mm x 10m Everbuild grey foam backer rod.

## Questions & Answers

**Q: Is it waterproof (ie. can it be used around baths & shower trays)?**
A: No it is not waterproof, it is meant to be used as a backing to fill the gap/void before applying the sealant (waterproof), all sealant manufacturers recommend you use a foam backing strip set back half the depth of the joint you wish to fill.

**Q: What gap width does this cover?**
A: With a the right tool you can get it into a gap of about 7mm minimum (but the joint needs to be 20mm deep as it squishes flat) and it will work(i.e. not dislodge) still up to about 16mm as long as it is being used with silicone to hold it in place in the permanent condition as it relies on compression to grip, probably 14 to 15mm if you use it dry.  If you are outside those limits then you need a different size rod.

**Q: Could this be used around an undertop sink gap before sealing?**
A: Can't see why not as it's function is to be squeezed in to a gap so it expands out to grip it's self within that gap and allows a backstop when you fill the gap (Designed for the gap between wall sections over a long distance). So you are not pumping in endless amounts of sealant in to the gap. Remember to position it slightly down from the actual surface level, so you have room for the sealant.

**Q: What colour is this product?**
A: dark gray
