Nanostructured water-based primer for emulsion paints
SurfaMix P is a versatile primer for surface preparation, before the application of emulsion paints.
SurfaMix P is a water based polymer primer with a particle size 60 nm that penetrate deep in the substrate yielding a coherent and solid result for the application of emulsion paints. It is used for painting many kinds of porous materials, such as concrete and especially substrates that are not water resistant and will be exposed to the natural elements. SurfaMix P can be also applied on already painted areas, when a paint refreshing is required. It reduces the water absorption coefficient of porous substrates and does not aﬀect the breathability of the substrate. It is slightly bluish in colour for identifying the application pattern. SurfaMix P is cost eﬀective, as it can be diluted in water up to 4 (porous cementitious renders or masonry) or times (painted substrates) its original volume.
Concrete, masonry, painted surfaces, plaster, cementitious renders, screeds and mortars.
Applicability: SurfaMix P can be applied directly on exterior or interior wall surfaces (masonry, concrete, plaster, drywalls), and wherever emulsion paints are to be applied. New substrates from cement or masonry should have cured for more than 3-4 weeks before primer application. Adverse conditions during or immediately after application may aﬀect the coating's properties.
Surface Preparation: Ensure all surfaces are clean and dry prior to application.
Application note: Shake well before application. For one volume part of SurfaMix P, dilute by adding 3 volume parts of water (porous masonry substrates) or 4 volume parts of water (paint covered surfaces). Application temperature should be between 8 - 35⁰C. Apply one even coat using a good quality brush, roller or by spraying with a tip of a diameter 1,4mm or more. Do not over-brush. Ensure corners and edges are adequately covered.
Spreading Rate: 8-12 m²/L depending on the porosity of the substrate.
Consumption Rate: 30-40 m²/L after dilution.
Drying Time: Typically 1 hour depending upon coat thickness. Low temperatures and high humidity will lengthen drying times. As a good practice, apply emulsion paints 24h after primer application.
