Weldbond as a glue:
Use Weldbond at full strength without diluting. Apply to one surface and press together. Allow to dry thoroughly.
Weldbond when bonding two porous surfaces:
When bonding two porous surfaces, surface sealing can be done prior to adhering for optimal results. Determine if the surfaces are porous by placing a drop of water on the surface. If the water lies on the surface, then sealing is unnecessary. If water soaks in, then you may want to prep the surface by sealing them with Weldbond. Porous surfaces can be primed by mixing one part Weldbond and five parts water, then apply liberally and allow to fully dry. Then spread a thin film of Weldbond on both surfaces. Clamp lightly and let dry.
Weldbond when bonding porous to non-porous materials:
Spread a thin film of Weldbond on both surfaces; place the surfaces together. The longer that it is let to cure, the stronger the bond will be. Weldbond cures by evaporation, and when it is fully cured the bond appears crystal clear.
Weldbond as a sealer:
Mix one part Weldbond with five parts water. This makes a porous surface sealer and primer. Concrete, plasterboard, or any surface that is porous can then be bonded or painted. This can save you a coat of primer.
Weldbond as a general adhesive mix:
For bonding any rough and uneven surface, mix one part Weldbond, with one part water and 4 to 5 parts filler (plaster, tile grout, mortar mix, sand-cement mix).
Please note:
Weldbond dries chemically in air. You can reduce curing time by allowing it to dry slightly before making the bond. This can reduce the curing time, but might also compromise a bit of Weldbond's strength. We suggest one to three days of curing time for maximum strength.
