PROPAM® REPAR PRIM

(Before BETOPRIM)
PROPAM® REPAR PRIM is a coating based on cement, quartz sand, acrylic resins and corrosion inhibitors. It constitutes a highly alkaline and active electro-chemical environment, which acts against corrosion, passivating the steel and presenting a coarse surface. It can be used as a bonding primer before applying the repair mortars. It complies with the requirements of standard EN 1504-7. It has CE Marking 2+, for uses in building and civil engineering works of all kinds.

Fields of application	PROPAM® REPAR PRIM is used as a rebar steel passivating agent to protect it against corrosion in: Rehabilitating concrete affected by corroded rebars, due to carbonation, freeze-thaw cycles, environment contamination, etc. New projects subject to aggressive environments. Chemical industrial plants, cooling towers, etc. Projects for marinas, piers, emissaries, etc. Water purifying plants. As a preventive measure on reinforced concrete elements with little coating and the risk of the rebars corroding or being contaminated by chlorides. PROPAM® REPAR PRIM can be used as a bonding primer to improve the adhesion between old and new concrete, or with repair mortars.
propiedades	Its inhibitors prevent corrosion and prolong the life of the rebars. It can be applied to damp surfaces. Perfectly compatible with the steel in the reinforcement and the repair mortars It forms a passivation layer on the rebar that is impermeable to gases (CO2, SO2, etc.) and water. Excellent adherence to steel and to concrete. Easy to prepare and apply. It is only mixed with water.
consumo	With 1 kg of PROPAM® REPAR PRIM you can treat 0,8 – 1 m2 Depending on the coarseness of the substrate, each application creates a dry layer thickness of 0.5 to 1 mm. It is always advisable to apply two layers to protect rebars. However, the final amount used will depend largely on the condition and porosity of the substrate.
