Cemix Multibond is a high performance latex bonding agent for bonding of a variety of products such as concrete, toppings, screeds, pavers, mortars and plasters. It can also be used with stone, tiles, slate etc. It is used as a multi-purpose bonding primer and admixture where high performance & durability are required. It can be spray applied for larger volume applications.
Typical Applications & Uses:
Substrates should be sound & rough to ensure a good bond. They should be uncoated & clean, free from all contaminants, loose particles, dirt, oil, mould, curing compounds, sealers & paints etc. Acid washing, rough honing or scabbling & then water blasting is required to prepare concrete surfaces depending on substrate condition. Washing with soap & water blasting may also be required if oil is present. The better the substrate preparation & condition the better the end result.
Admixture: Replace 25% – 50% of the mixing water with Cemix® Multibond.
Slurry: Mix 1.5 – 2 parts of cement with 1 part of Cemix® Multibond.
Primer: Dampen each substrate avoiding ponding & then thoroughly prime the entire surface with Cemix MULTIBOND brushed or sprayed undiluted into the surface. Firmly apply the mortar or concrete into the surface to obtain a wet bond, while the MULTIBOND is still wet. Do not let the MULTIBOND dry.
It is important to agitate this product well before use.
Cemix® Multibond has a shelf life of 12 months minimum when unopened in original containers.
Clean all tools with water & brush immediately after use.
