Paint Barrier AQ is a silicone free complex of synthetic resins which gives a colourless protective film to the surfaces upon which it has been applied. that resists water and bad weather. Paint Barrier AQ can be applied on most types of surface including concrete, cement mixtures, stone, brick, block, resistant paints etc. Paint Barrier AQ prevents the pigments and solvents, contained in paint, forming a permanence as well as the adhesion of stickers and posters. It also has the advantage of protecting the treated surfaces against the solvents held within the paint or adhesive. What does all of the mean? If someone sprays graffiti or paint, sticks a poster or writes with a permanent marker onto a treated surface then you will be able to remove it with little effort. We recommend mixing the product prior to use which is easily done by either shaking the container or stirring the contents for a few moments to ensure there is no separation of the Paint Barrier AQ which can happen whilst the container is in storage. Once this is done, and you have prepared your surface, then you are ready to start application. The viscosity of Paint Barrier AQ makes it an easy product to apply and very user friendly so application is easy and not time consuming. Once dry, the Paint Barrier AQ is colourless so does not change the normal look or appearance of the surface. Paint Barrier AQ maintains its function for up to 5 years.
