## Overview

SIKA Everbuild Everflex Fire Mate is a high-performance intumescent acrylic sealant that expands over 150% when exposed to heat, providing up to 5 hours of fire resistance. It offers permanent flexibility with 100%+ elongation, excellent acoustic noise reduction of 24dB, and fast curing to a tack-free finish in just 15 minutes. No priming is required on most substrates, and it can be overpainted for a flawless finish, making it the go-to sealant for professional fire and soundproofing applications.

## Description

Everbuild Everflex Fire Mate Intumescent Acrylic Sealant, the Everbuild range of fire sealants are five hour rated, one part, emulsion acrylic based, intumescent acoustic sealants that give a firm yet flexible seal to joints in a variety of fire-rated structures. Everflex Fire Mate, in suitably designed joints, will resist the passage of fire for up to 5-hours. The selected fillers used in this formulation also make it suitable for use as an acoustic sealant. When exposed to heat, Everflex Fire Mate swells greater than three times its original size, so creating a char that will resist the passage of fire for up to five hours. No priming is required prior to application on most construction substrates. This product is fire rated to EN1366-4 (2006). Acoustic rates to BS EN ISO 140/3 and is tested for air permeability to EN13141-1.

Review: Does what it says
Review: Firstly, the price listed here cannot be correct. I've seen the same stuff in various other places for between eight and eleven quid not the eye watering list price here. Fortunately this was a review item so I will do so based upon the price elsewhere found not the OTT one on this page. As a sealant it works well - just like any other to be honest. The good bit being that when used in transitions through fire walls it will expand to seal off any gaps if put under heat. I would imagine that if you were super careful you could even used this as a sealant on a door. It feeds out easily and smoothly - although to fess up I use a Ryobi battery caulking gun which allows much better control than the hand operated ones. Overall at a sensible price this is a good product. At the list price here you would need your head examining to buy it.

*by R***S on 5 August 2019*

Amazing product which could save your life. Not the cheapest product on the market but worth every penny in the case of fire. Its easy to apply using a regular sealant gun and is great for beading and sealing around door and windows as in the event of fire it swells to 1.5x its original size thus blocking out oxygen from entering and smoke and fire exiting. I've used this around pipes and cables which breach a firewall in my new extension and I hope I never have to test its effectiveness. Excellent product
