Corrosion-Proof Cement Slurry for Steel Reinforcement
BETOFER is a two component cement based mortar. Component (A) is a powder consisting of hydraulic binders and special additives. Component (B) is a liquid consisting of selected polymers and migrating inhibitors of corrosion. The two components must be mixed at the moment of use without addition of water or any other product.
BETOFER is packed in two components kit; 1.5kg Powder in plastic bag and 0.5 kg Liquid in plastic bottle.
0.65 m²/kg for 1 mm thickness
The product must be kept in dry well covered place at temperature not less than +5ºC and not more than +35 ºC. Shelf life is 12 months if stored as recommended.

BETOFER is composed of two components that must be mixed at the moment of use. Pour the liquid (Component B) into a clean container and then add the powder (Component A). Mix till a homogeneous lump free mix is achieved. The mixture must be applied within 45 minutes from its preparation.
Apply BETOFER using a brush in one coat. If necessary to apply second coat, it should be applied at a right angle to the previous coat after at least 2 hours and within 24 hours from the previous coat. Make sure that the whole steel surface is completely covered. The average total thickness of BETOFER should not be less than 1 mm.
Repairing mortars such as BETOCEM FIBRE, BETOCEM HCS or BETOCEM HR) can be applied after 4 to 5 hours from the time of applying BETOFER.
Tools and equipment used should be cleaned promptly with SOLVENTE 10.
Protect the applied product from the direct sunrays, freeze and rain up to the complete hardening
During Summer Season, working area should be covered to prevent the direct sun effects. Keep equipment and material cool
The reinforcing bars must be clean from weak concrete, grease substances and rust. Sandblasting would be advisable for cleaning deep rust. Continue cleaning until all rust is removed. Exposed reinforcement can also be cleaned mechanically or by using a stiff brush tool.
During application, wear appropriate protective clothing, goggles, gloves and respiratory equipment if necessary.
In case of contact with skin, rinse with water and again wash thoroughly with soap and water. In case of contact with eyes, rinse with plenty of water and seek medical advice accordingly.
If ingested, obtain medical attention immediately. Do not induce vomiting.
