Newton HydroCoat LiquaBond – Acrylic Bonding Agent & Admixture
Newton HydroCoat LiquaBond is a formulated acrylic admixture used both as a primer for significantly increasing the bond in wet-to-dry cementitious systems, and as a high performance admixture which waterproofs cement-based mixes as well as greatly increasing the adhesion of the product to the substrate.
KEY BENEFITS
- High bond strength – Provides excellent adhesion when used as a bonding agent or as an admixture in cement-based mixes
- Resilient – When used as an admixture, an acrylic lattice is formed throughout the mix, greatly reducing brittleness and enhancing resistance to impact damage
- Water resistance – Combines low permeability with resin stability in continuously wet conditions when used in cement-based mixes
- Versatile – Easy to use with a high bond to a wide range of materials such as brick, stone, concrete as well as a number of different metals and plastics
- Delayed bonding – When used as a bonding agent, subsequent toppings may be applied immediately or up to 7 days later
- Eliminates the need for water curing
- Product stability – Specially formulated for maximum performance under alkaline conditions of cement mixes. Unlike PVA systems, the bond film will not hydrolyse under wet conditions
SUITABLE SUBSTRATE
- Concrete
- Mortar
- Stone
- Cement-based waterproofing slurries
- Screed
- Render
- Metals
TYPICAL APPLICATIONS
- As a primer to increase the adhesion of HydroCoat Tanking Slurry as well as those from other manufacturers
- As a primer to increase the adhesion of render to cement/acrylic waterproofing membranes such as HydroCoat 103 2K and HydroCoat 107 Elastic 2K
- As an admixture and primer to increase the adhesion of render to nonporous surfaces
- For priming of construction elements prior to sealing and lapping with butyl tapes
- Increases the bond of internal angle fillets
- As an admixture to sand/cement screeds to provide a fully bonded screed
- As an admixture to sand/cement repair mortar providing greater workability and adhesion
- Bonding agent between new and old concrete
- Bonding agent between render and brick and concrete walls
- Sealing walls and ceilings prior to painting in high humidity areas such as bathrooms and kitchens
COVERAGE & YIELD
Coverage is determined by the density and porosity of the substrate. The figures below are for guidance. Yield is determined by the ratio of cement within the mix and by the required consistency. The figure below is a fairly rough guide based upon a dense, medium to dry, 4:1 sand/cement screed/render mix.
- As a tack coat – dense, smooth concrete – 0.15 litres/ m²
- As a tack coat – medium density concrete – 0.25 litres/m²
- As a tack coat – older or rough concrete – 0.4 litres/ m²
- As a tack coat – smooth and impervious materials – 0.10 litres/m²
- As an admix – 1:10 which is 100 litres/m³, 10 litres/100 litres and 1 litre/10 litres of screed/render
