Renders & Base Coats

Dashing Renders

Alumasc Dashing Renders are used to receive the DashAgg stone dash finish for an External Wall Insulation (EWI) system (MR S7) or un-insulated render only applications (MR S5). The dashing renders are supplied as dry, pre-mixed polymer and fibre reinforced powder and are approved for use in a number of Alumasc’s BBA certified systems. When fully cured, Alumasc Dashing Renders will be non-flammable and will remain unaffected by the temperature extremes that occur in the UK climate.

Polymer Render Base Coats

Alumasc Polymer Renders (MR S4 & MR S5) are single coat renders that are typically finished with either poly-kote masonry paint or Silkolitt+ silicone render. The MR S4 version of the Alumasc Polymer Render is used in insulated External Wall Insulation (EWI) applications whereas the MR S5 formulation is used in render only applications.

Alumasc Polymer Renders are breathable, flexible polymer-reinforced renders that are non-flammable and weathertight when cured, but will freely allow the transmission of water vapour.

Alumasc Polymer Renders are available in a range of colours.

Reinforcement Renders

Alumasc reinforcement renders are used to provide the construction with the requisite flexibility, impact resistance and durability.

Alumasc Base Coat is a polymer-modified mineral reinforcement mortar that is an integral part of lightweight, thin coat render systems. The Alumasc Scrim Reinforcement mesh is bedded into Alumasc Base Coat.

Alumasc Scrim Adhesive is a polymer-modified reinforcement adhesive that is specifically designed to adhere the Alumasc Scrim Reinforcement mesh to the insulation board. Alumasc Scrim Adhesive is typically used with Alumasc Polymer Renders or Alumasc Dashing Renders.

Dubbing Renders

Alumasc Dubbing Render (MR S5) is used to ensure that the substrate is line and level prior to the installation of an Alumasc External Wall Insulation (EWI) system or render. The dubbing render is supplied as a dry, pre-mixed polymer and fibre reinforced powder and is approved for use in a number of Alumasc’s BBA certified systems. When fully cured, Alumasc Dubbing Render will form a weather-tight, breathable and flexible reinforced base coat render.

Insulation Adhesive

Alumasc Insulation Adhesive is a polymer-enhanced adhesive that is designed to adhere insulation boards to continuous masonry substrates or cement particle carrier boards. Alumasc Insulation Adhesive is supplied as a dry, pre-mixed polymer-modified powder and is approved for use in a number of Alumasc’s BBA certified systems. When fully cured, Alumasc Insulation Adhesive will be weather-tight, but will freely allow the transmission of water vapour.
