Brand: DMAR
Model: DMAR DPS
Description:
DMAR DPS is an environmentally friendly, non-toxic, non-flammable, odorless, clear, water-soluble liquid compound, which is safe and easy to use. DMAR DPS outlasts and outperforms every other sealant on the market today. It is inorganic and based on natural minerals, affecting neither your health nor the environment.
Uses:
DMAR DPS has the ability to extend the lifetime of concrete structures by protecting them against the elements to which they are subjected on a daily basis, such as rain, salts, oils and chemicals which all wear down the integrity of the concrete over years, leading to unsightly stained surfaces and gradual structural decay. DMAR DPS can be used on most old and new concrete and cementitious surfaces.
How does it work?
DMAR DPS penetrates below the surface and chemically reacts with the alkali and lime found in concrete. This reaction creates a silica gel membrane within the pores and capillaries of the concrete, permanently sealing it against the ingress of moisture yet allowing the concrete to breathe. Over a period of time the silica gel membrane hydrates and solidifies into a crystalline structure, increasing the hardness and strength of both new and old concrete whilst reducing moisture vapor emissions and permanently stopping the penetration and flow of water and water-borne contaminants such as chlorides and acids, both on the positive or negative side.
