The Armor AR350 is a solvent-based acrylic sealer designed to enhance, seal, and protect concrete and paver surfaces. It will darken the surface and enhance any dull and faded coloring and protect the surface with a durable low gloss surface film. The Armor AR350 is a fantastic sealer if you are looking to bring out dull and faded surfaces and enhance surfaces with a low gloss wet look finish. The Armor AR350 is made from high-quality, non-recycled, US-manufactured resins. It is non-yellowing, breathable, and has low VOC. The protective low gloss film will reduce damage and deterioration caused by surface abrasion and water absorption including cracking, spalling, pitting, dusting, and the growth of mold, mildew, and algae. The Armor AR350 is designed specifically to be used on unsealed concrete and concrete pavers. It can also be applied to concrete and concrete paver surfaces previously sealed with solvent-based acrylic. The Armor AR350 should not be used to seal clay brick, red Chicago pavers, flagstone, slate, or natural stone. If you are looking to seal clay brick, red Chicago pavers, flagstone, slate, or natural stone, consider instead of the Armor WL550 or the Armor SX5000 WB. The Armor AR350 can’t be applied over any other film-forming sealer, other than a solvent-based acrylic sealer. It can’t be applied over water-based acrylic, acrylic latex, paint, epoxy, or urethane. Appearance When applied in clear, the Armor AR350 will darken the surface to bring out the natural coloring of the concrete or pavers, and seal it with a transparent low gloss finish. When applied in a color, the Armor AR350 will cover the concrete or pavers like paint (opaque). The actual level of gloss and enhancement received will depend on the type and age of the surface, age, porosity, condition, applicator, application method, and amount of material applied. For an accurate representation of what your surface will look like once sealed, we suggest applying the product to a test area first. Product Life When properly applied, the Armor AR350 can provide up to 1-3 years of life on an exterior surface before the need to recoat, and up to 2-7 years of life on an interior surface. While the Armor AR350 is designed to out-last and out-perform similar products on the market, there are several factors that can impact actual product life including the severity of surface abrasion and level of foot traffic, the porosity of the concrete or pavers, and the amount of resin build-up on the surface. Some surfaces need to be sealed every year, while others can go a few years without sealing.
