DescriptionMapei Quarzolite Base Coat 20kg is a coloured acrylic undercoat in water dispersion, with micro-granular quartz and selected charges. It is used to even out the absorption of the substrate and promote bonding of successive coats of paint and layered finishing materials from the Quarzolite range.For professional use onlyUsed to prepare the base layer on cementitious surfaces before applying the final colouring coat, to regulate absorption of the substrate and improve bondingIndispensable when “scratch-effect” finishes are applied, to avoid the substrate showing through the more transparent partMay be used to level the surface, by creating an even finish and by covering small imperfectionsUniformly rough finish, which makes it easier to apply layered finishing materials, particularly when applied by trowel. This results in a more even distribution of the finishing material over the entire surfaceFeatures & BenefitsWhen applied in white, or in a colour similar to the final coat, it helps to integrate the final coat particularly when bright, lively colours are applied, which do not usually have good covering propertiesBase filling layer, with quartz granules, for new, well-cured render before applying layered finishing materials from the Quarzolite rangeBase levelling and filling layer for old render, if not excessively deteriorated or crumbly, before applying layered finishing materials from the Quarzolite rangeBase layer on old paintwork, including paintwork which is slightly flaky, before applying layered finishing materials from the Quarzolite rangeBase layer with the same colour as the final layer, to help cover the final layer of paint or layered finishing material in bright, lively colours, which are clean and only offer partial coveringRecommendationsDo not use Quarzolite Base Coat on metal surfacesDo not apply Quarzolite Base Coat if the temperature is lower than 5°C or higher than 35°CDo not apply Quarzolite Base Coat if the humidity is higher than 85%Do not apply Quarzolite Base Coat on damp or partially-cured substratesDo not apply Quarzolite Base Coat if rain is forecast, in windy weather or under direct sunlightQuarzolite Base Coat is not a consolidator and should never be applied on detached surfaces that are not firmly anchored to the substratePreparation of the SubstrateNew surfaces or surfaces patched up with repair mortar must be cured, perfectly clean, sound and dry. Remove all traces of oil and grease and parts which are not well-attached from the surface. Seal any cracks which are present and repair any deteriorated areas. Seal off the porosity and smooth off any uneven parts in the substrate.Preparation of the ProductQuarzolite Base Coat may be used neat, or diluted with 5-10% water. Make sure that the product is well blended, and use a low speed drill if possible for blending. If only a part of the product is to be prepared, mix the Quarzolite Base Coat in its original container before pouring off the quantity required.ApplicationMix Quarzolite Base Coat well before use, and apply it using conventional techniques with a brush, a roller or by spray (air mix).A single coat of Quarzolite Base Coat is usually sufficient to prepare the substrate. However, if the substrate is particularly uneven, a second coat may be required.Protect from rain for at least 12 hours.Quarzolite Base Coat may be painted over after 12-24 hours.Cleaning: Clean Quarzolite Base Coat from brushes, rollers and spraying equipment (air mix) before it dries with water. Consumption is heavily influenced by the absorption and the roughness of the substrate and by imperfections on the surface, and according to the application technique used.Under normal conditions, consumption is generally 0.3-0.5 kg/m² per coat.Browse all Mapei Products.
