Published:  15 May, 2015

The Seal-a-Leak liquid repair kit from Sealoflex Liquid Waterproofing is designed to deliver a complete or emergency waterproofing repair to damaged or punctured flat roof membranes. Each kit comprises of an amount of liquid coating, primer and reinforcing fabric and is intended for use in all types of roofing application. Watch this demonstration video to see how it works!



Emergency Repair

Where a flat roof membrane is visibly punctured and water is entering the building, Seal-a-Leak solves the problem with one simple application that provides an immediate patch repair. Capable of being applied above damp substrates, the single component liquid immediately plugs the puncture, stopping water from entering the building and causing further damage.


Complete Repair

Where a more permanent repair is required, application of the liquid coating incorporating the reinforcing fabric above the prepared surface can provide a long lasting repair that is rainproof in less than 30 minutes.

Nick Smart-Jones at Sealoflex Liquid Waterproofing said: "We are proud to present Seal-a-Leak to the industry, providing a fast, yet effective solution to installers of all capabilities for patching a damaged flat roof membrane."

Once opened, the Seal-a-Leak kit is completely reusable, making it the ideal product to keep for an emergency.
