REQUIREMENT:
Bonding to brick, concrete or masonry, without roughening or hacking. Bonding agent for interior renders and toppings, as well as for bonding concrete at concrete construction joints, etc.PRODUCT TO USE:
CALBONDHOW TO SPECIFY:
All surfaces (state areas) shall be prepared for plastering/rendering by application of a liberal coat of CALBOND which shall be allowed to dry to a “tacky” condition (10 – 20 minutes) before applying render or plaster. Consult manufacturer for details of surface cleaning, etc.
EFFECTS:
CALBOND forms a plastic “key” into the surface pores of the base masonry, which when not fully dry will partially re-dissolve in the damp render or plaster. When set and dried, the whole sets into a hard, tough unit strongly assisting firm adhesion of the surface render. Fully compatible with all CEMENTAID products.
WHERE RECOMMENDED:
All rendering onto non-roughened surfaces, including integrally waterproofed concrete.Repair of cracks and faults in masonry.
As admixture in mortar or concrete mix, where elasticity and toughness are required
NOTE: For service under wet areas or wetting drying conditions, Cementaid WELDCRETE is recommended to be used instead.
FOR NEW FLOOR TOPPINGS
A slurry of CALBOND and cement mixed in the proportions of 2 parts CALBOND, 2 parts cement and 1 part water, when applied liberally on a clean surface will assist adhesion of applied toppings.
All toppings must be well cured.
