December 2021, Version 01.01 021830101000000036 PRODUCT DATA SHEET Parex MAITE-D COLOURED OVERCOAT AND DASH RECEIVER
DESCRIPTION
MAITE-D is a pre-coloured decorative overcoating render and dash receiver. USES Maite D provides a breathable, weatherproof and dec- orative finish for masonry, concrete or rendered ma- sonry substrates. It can also be used with the PAREXTHERM and PAREXDIRECT render systems. The system also provides an effective additional weatherproof coat over an existing render and can avoid the addition of an extra levelling coat when dealing with surface imperfections not exceeding 3 – 4 mm. CHARACTERISTICS / ADVANTAGES Provides a breathable, weatherproof and decorative finish for masonry, concrete or rendered masonry sub- strates PRODUCT INFORMATION Composition COMPOSITION Hydraulic mortar containing: Cement.▪ Lime.▪ Siliceous and calcareous sand.▪ Mineral pigments.▪ Specific admixtures.▪ Packaging 25 kg bag Shelf life 12 Months from date of manufacture Storage conditions Dry frost free conditions Appearance and colour Colours available: Natural White G00 Pale Yellow J20

Actual measured data may vary due to circumstances beyond our control. IMPORTANT CONSIDERATIONS Product intended for professional use.▪ It is advisable when completing the different fin- ishes, to take into account the hardening time, which will vary according to climatic conditions. Avoid applications on substrates exposed to direct sun or in hot drying winds. Do not apply on over heated substrates. In hot con- dition dampen the substrate prior to application. Dampen the render after application. Do not apply to a frozen substrate or on thawing substrates. Do not use in freezing conditions. Take precautions during damp climatic conditions. Discol- ouration could occur). Do not apply on very wet substrates or where there are wet patches. (Discolouration could occur). Minimum application temperatures: +5 °C for light colours, +8 °C for dark colours. Over 30 °C, special precautions must be taken.▪ In order to reduce the risk of colour differences after drying, always use the same batch number for the same façade In order to avoid the risks of correcting and to facilit- ate application of the dash chippings, it is advisable to divide the surfaces to be covered into panels of 15 to 20 m² maximum. Avoid creating straight line joints in the finish by blending the chippings across the panels as you pro- gress. Avoid allowing the receiver coat to form an initial cure or surface crust, as the chippings will not stick. To avoid possible changes of shade, complete whole wall areas in one single application and continuously mix the MARBRI DASH bags in quantities of 3 to 4 bags, adding successive new bags before applying to create an even spread of dash colour. ECOLOGY, HEALTH AND SAFETY Wear suitable protective clothing, gloves and eye / face protection. This product contains materials which may cause an allergic reaction, is irritating to eyes and harmful if swallowed. In case of contact, seek medical advice. Keep out of the reach of children. Read and follow the guidelines in the Health and Safety data sheet for this product APPLICATION INSTRUCTIONS EQUIPMENT EQUIPMENT REQUIRED Application by machine Spray Render Machine Constant Mix and Pump Ma- chine Pump Pressure 10-12 bar (water) 2.5-6 bar (water) Pumping dis- tance/height Up to 120 m/60 m approx Up to 50 m/30 m approx Power Source Diesel Electric - Based on PFT G4/G5.

Clay blocks e.g. Porotherm*.▪ Standard low and normal density lightweight con- crete blocks. Breeze blocks (clinker).▪ Stone/rubble stone.▪ Shuttered concrete.▪ Expanded clay insulation blocks.▪ Clean, sound, well adhered existing render. Base coats conforming to BS EN 13914-1 PAREX grey weather resistant base coats,e.g. MONOGRIS E, PARMUREX.*Consult manufacturer’s data sheets. As an over dashing coat to existing dashed render substrates. Insulated concrete formwork systems (ICF)(1) External & internal applications.▪ Can be applied to exposed locations such as external walls, parapet walls, balconies etc. UNSUITABLE FOR PARILIEN, PARLUMIERE CLAIR and all hydraulic renders with a hardened density below 16 kg/kgm3. This generally applies to lime based renders which a cement based material such as MAITE-D should not be applied to. (1) ICF is generally made from moulded /extruded EPS which has a shiny surface finish not suitable for receiv- ing a render finish. Before applying the render, make sure the ICF receives a light sanding to create a Product Data Sheet Parex MAITE-D December 2021, Version 01.01 021830101000000036 2 /
roughened bonding surface. SUBSTRATE PREPARATION Substrates must be clean, sound, dust free and free of any material which may prevent adhesion. Re- move all traces of plaster, paint, etc. Construction of the masonry must comply with BS 8000-3. On low suction e.g. concrete or high suction e.g. Lightweight aircrete or clay blockwork, first apply a coat of ready-to use MICRO GOBETIS 3000. On wet or wet patchy substrates or where different materials have been used it is advisable to apply a key coat made up by adding 0.5 L of 751 LANKOLATEX to the mixing volume for a 25 kg bag of MAITE-D. Allow the key coat to fully dry a minimum of 48 hours before the application of the next coat. This suggestion will assist against the effect of ‘block ghosting’, lime blooming and shade variation. TV10 MESH or 355 AVU MESH may also be required, dependent upon substrate condition and project specification. APPLICATION Refer to and comply with the Substrate Preparation first. For high exposure or coastal zones please contact Parex® for additional guidance as the render thick- ness may need to be increased and additional sur- face treatment may be recommended. Ensure the product is mixed correctly with the correct water content and do not allow the render to cure too quickly as surface holes in the render could occur. FOR WEATHERPROOFING APPLICATIONS TO CON- CRETE BLOCKS, CLAY BLOCKS, LIGHTWEIGHT AIRCRETE BLOCKS, BRICKS, ETC. FLOAT FINISH: Spread and level MAITE-D on the flat substrate, 6 mm deep using a notched plastering trowel no.5. Smooth off level with a steel float. Ensure to check on mesh requirements. OVERCOATING TO RECEIVE A DASH: Spread and level MAITE-D using a stainless steel trowel to a nominal thickness of 8mm leaving a flat finish. Immediately cover the MAITE-D with MARBRI DASH chippings using an appropriate spray applicator in one application using a backwards and forwards movement or by hand using a traditional hand thrown technique. FOR DECORATING WATERPROOF CONCRETE AND MA- SONRY SUBSTRATES I.E. COVERED WITH AN EXISTING SOUND AND WEATHERPROOF RENDER. FLOAT FINISH: Spread and level MAITE-D on the flat substrate, 4mm ▪ deep using a notched plastering trowel no.5. Smooth off with a steel float. Ensure to check on mesh requirements. OVERCOATING TO RECEIVE A DASH: Spread and level MAITE-D using stainless steel trowel to a nominal thickness of 6mm leaving a flat finish. Ensure to check on mesh requirements.
