Reverse Water Barrier
RWB (Reverse Water Barrier), formerly known as HW, is an eco-friendly waterborne product that effectively blocks water infiltration from the rear side of concrete substrates. When applied to the concrete surface, it penetrates 7-15 cm deep, filling pores and bonding with concrete components to form a hydrophobic seal.
Description
RWB, Reverse Water Barrier, previously HW, is an eco-friendly waterborne product that effectively seals off water infiltration from behind concrete substrates. When applied to the concrete surface, it penetrates 7-15 cm deep, filling pores and bonding with concrete components to create a hydrophobic seal.
Super Hydrophobic Sealant: RWB incorporates a catalytic agent that interacts with the alkali content within concrete, converting it into a natural compound. This compound effectively fills concrete pores and forms a tight bond with the pore surface, creating a hydrophobic seal.
Increases Concrete Surface Density: Due to its bonding and pore filling characteristics RWB adds density to the upper layer of the concrete increasing hardness and durability. It can be used on old and new concrete including bridges, walls, ceilings, floors, parking garages, decks, loading docks, and driveways.
Exceptional Tensile Strength: RWB serves as the perfect protective sealant for surfaces subjected to heavy tensile loads, including loading docks, parking lots, dams, and bridges. Its remarkable bonding strength at the upper layer of concrete enables it to withstand high tensile forces effectively.

Application Spray Protocol
RWB spray application for small/restricted areas can be achieved with the use of HPLV spray equipment. Pressure and atomization are the key elements.
2000 PSI-138 bar is essential for proper application. This allows for proper separation of the active ingredients and the carriers which allows for integration and penetration of RWB. This spec can be found in a HPLV system. Regulated spray pot pressure will apply best at 20-100 PSI / 1-7 Bar, this will be equal or slightly less at the fluid nozzle or tip at the gun/the length of spray lines.
Air pressure at the air cap on the gun should be at 40-80 PSI / 3-6 Bar to give the spray a finer mist. A smaller tip size found in the HPLV equipment allows for less over spray, better containment of waste, faster application times, and reducing cost. Larger airless equipment is better served for higher square meter / square foot projects where hoses and over-spray are less likely to affect the outcome.
