As a Bonding Agent: For bonding new concrete to old. Repairs almost any cracked or flaking concrete surface. You can trowel out your cement to a featheredge,
with no separation. May also be used with coloured cement or decorative concrete.
1st step. If required prime or seal the surface (see below)
2nd step. Apply a bonding coat of 3 parts Weldbond and 1 part water. While this coat is still tacky, pour your cement slurry mixture on top.
As a Sealer: Weldbond seals concrete, masonry, brick & motar joints (or any other porous surface). Great for sealing in concrete dust! Use prior to painting and save on a coat of paint! 1 gallon (3.7 litres) of Weldbond, once diluted covers 2200 square feet (54 square meters). Just mix 1 part Weldbond with 5 parts water, and brush or roll over surface. Results in a non-slip matte finish. Test to make sure surface is porous, and is free of oil, gas & film deposit.
Note: One sealing coat only. Do not repeat applications. Not recommended for Interlocking brick, or for areas with standing water.
For Strengthening / Hardening: Concrete blended with Weldbond can withstand heavy wear and vibration.
Just mix 1 part Weldbond with 10 parts water, and use as the water portion, to make up your premixed concrete. Then follow concrete manufacturer’s directions. The SHEER STRENGTH of concrete will increase up to 1200%, and the COMPRESSION
STRENGTH up to 38%.
