## Overview

Everbuild External Frame Sealant is a 290ml acrylic-based, permanently flexible sealant designed for both interior and exterior use. It offers mould resistance, a no-slump formula, and is overpaintable in four colors to ensure a seamless finish on timber, metal, PVCu, brick, stone, and concrete surfaces. Easy to apply with standard sealant guns, it provides a durable, long-lasting seal that protects and perfects your frames and cracks.

## Description

From the manufacturer HOW TO APPLY? All surfaces must be clean and dust free. All loose or flaking surface coatings, and old sealant and mastic joints, should be removed before application. Cut the tip of the cartridge taking care not to damage the thread. Apply nozzle and cut cleanly at an angle of 45° with an opening slightly larger than the gap to be sealed. Apply using a standard sealant gun. Best results will be obtained by keeping an even pressure on the gun trigger and keeping the gun at a constant angle to the surface being sealed. Smooth down within 20 minutes of application using a wetted spatula, piece of wood or smooth down tool. Care should be taken at this point not to saturate the surface as this will delay drying.

Review: Great sealant in a lovely neutral colour. - Great sealant in a lovely neutral colour.
Review: Used on external door frame, did not wash away. - I noticed some comments about this washing away in the rain. It did take a couple of days to set hard but this has set fine and not washed away (yet). It feels gritty, perhaps that's the colour of the silicon. For the price I couldn't argue, I've even used this in my shed to seal up two external facing vents. I believe this is a good silicon for general purpose but from a professional point of view I can not comment.

## Features

- OVERPAINTABLE – Apply this ready-to-use thixotropic paste to most surfaces and paint over it for a seamless finish, overpainting is recommended externally to prolong the working life of the product.
