Drybase Bondaid Plus (SBR)
Drybase Bondaid Plus is a high-strength styrene-butadiene rubber latex bonding compound (SBR) with 46% solids. It is specifically designed for use with cement compositions and as a primer to improve bonding. When incorporated into cement mortar or render mixes it can drastically improve adhesion, improve tensile and flexural strength and provide greater resistance to water and water vapour.
Improves Workability and Strength
The SBR polymer in Drybase Bondaid Plus allows the mixes to become easier to work by facilitating the flow and movement of the angular sand and cement during mixing. It’s bonding capability will also impart render and slurry mixes with extra strength.
Mixing Drybase Bondaid Plus into slurry coats and render mixes helps to create greater adhesion due to its inherent bonding properties. This allows for easier application onto walls with low suction and surfaces where the key is less than ideal.
Improves Resistance to Shrinkage and Cracking
A common problem with newly-applied mortars and renders is the appearance of cracks due to shrinkage during curing. The increased flexibility and tensile strength introduced to mortars and renders by Drybase Bondaid Plus helps to resist this cracking.
Increases Resistance to Salt Efflorescence
Drybase Bondaid Plus increases a mortar or render’s resistance to salt efflorescence as a result of the SBR polymer reducing flow through the pore structure.
The Contractor’s Secret Weapon
Drybase Bondaid Plus is the super-versatile bonding compound that is the contractor’s best-kept secret. Whenever you’re working with renders or mortars this high-quality SBR with 46% solids can make the job easier.
