TamCrete Bond & Seal
Overview
TamCrete Bond & Seal is a formulated acrylic admixture used both as a primer for wet-to-dry cementitious systems and as an emulsion in mixtures.
Enhanced chemical resistance - the cementitious resin lattice within the rendering matrix greatly reduces the ingress of chloride ions and other deleterious materials.
Key specification
- Acrylic bonding agent
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.
- Enhanced chemical resistance - the cementitious resin lattice within the rendering matrix greatly reduces the ingress of chloride ions and other deleterious materials.
- Water resistance - combines low permeability with resin stability in continuously wet conditions when used in cement-based mixes.
- Versatile - easy to use with positive bond to a wide range of materials such as brick, stone, concrete, timber and most metals.
- Product stability - specially formulated for maximum performance under alkaline conditions of cement mixes. Unlike P.V.A systems, the bond film will not hydrolyse under wet conditions.
- 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.
Typical applications
- Repairs mortar in sewage and water treatment plants
- Repairs to spalled and damaged concrete
- New to old concrete
- Renders to brick or concrete walls
- Sealing walls, bathrooms and kitchen ceilings before painting
