Bonding Agents
Product Guide
For more information, see the Product Selection Guide.
Suggestions for form bonding agents include, but are not limited to, the following:
- Types of bonding agents:
Nonreemulsifiable - Generally an acrylic latex emulsion (Strong Bond)
Reemulsifiable - Generally a polyvinyl acetate (PVA) emulsion (Ready Bond) - Use a nonreemulsifiable bonding agent for exterior applications or anywhere it frequently comes in contact with moisture.
- Use a reemulsifiable bonding agent for interior applications not routinely exposed to moisture. These types of bonding agents can lose bond and fail if exposed to moisture for an extended period. However, these bonding agents can be allowed to dry to the touch and then they will re-wet when the concrete or mortar is applied. This provides more "open" or working time for the applicator.
- Some nonreemulsifiable bonding agents must not be allowed to totally dry to the touch before the concrete or mortar is applied. If this happens, the bonding agent can become a bondbreaker and the bond will fail. Always reapply these bonding agents if they dry out before the concrete or mortar can be placed.
- An acrylic latex emulsion or a PVA emulsion can be mixed with portland cement to create a bonding grout mix. These types of slurries are quite common and, when used, should be scrubbed into the concrete with brushes immediately before applying the topping or patching material.
- An acrylic latex emulsion or a PVA emulsion can be used as an admixture for cement-based products like grouts, repair mortars, etc. As an admixture, these products promote a strong bond and improve the curing, long-term durability, flexural and tensile strengths, and crack-resistance of the finished product.
