Mixing

• The components should not be mixed until the application is ready to start and should be applied as soon as mixing is completed
• The two components are supplied in pre-measured ratios:
  • Part A: 3 parts by weight
  • Part B: 1 part by weight
• Mix the two components completely and accurately with a low speed mixer until a uniform mix is obtained

Application

Power Floated and New Substrates:

• The substrate should be abraded by mechanical means to remove any curing agents or contamination, to assist penetration and adhesion of the membrane
• The area should then be thoroughly vacuumed to remove all dust and debris
• Apply the first coat of Mapeproof ESM ensuring it is well worked into the substrate and that complete coverage of the area is achieved at a maximum rate of 20m² per 4kg unit (depends on the porosity of the sub-floor) and allow to cure (approx 5 hours)
• Apply the second coat of Mapeproof ESM at right angles to the first coat, again ensuring complete coverage
• When the second coat has cured, a coat of Eco Prim T Plus or Eco Prim Grip primer should then be applied within maximum 24 hours (primer drying times vary with ambient conditions i.e. temperature and humidity)
• The levelling compounds should be applied within 24 hours of the primer application

Sand/Cement and Existing Substrates:

• All existing materials, adhesives, laitance and contamination should be removed prior to preparation work commencing
• Any cracks in the substrate should be filled with Eporip
• Where the substrate has a textured or profiled finish, Latexplan Trade levelling compound should be applied to provide a level surface for the membrane to be applied onto
• Apply the first coat of Mapeproof ESM ensuring it is well worked into the substrate and that complete coverage of the area is achieved at a maximum rate of 20 m² per 4 kg unit (depends on the porosity of the sub-floor) and allow to cure (approx 5 hours)
• Apply the second coat of Mapeproof ESM at right angles to the first coat, again ensuring complete coverage
• When the second coat has cured, a coat of Eco Prim T Plus or Eco Prim Grip primer should then be applied within maximum 24 hours. (primer drying times vary with ambient conditions i.e. temperature and humidity)
• The levelling compound should be applied within 24 hours of the primer application
• If required, the second coat of Mapeproof ESM can be blinded with sharp sand (when still fresh), which removes the need for a primer
• It is essential that pinhole free coatings be achieved

Underfloor Heating:

• The screed must be allowed to cure for a minimum 28 day period
• The underfloor heating must be commissioned prior to the installation commencing; it should be turned on to +5°C and the temperature increased by +5°C per day up to a maximum +27°C, run at this temperature for several days then cooled down and switched off for at least 48 hours
• Up to a level of 97% RH, 2 coats of Mapeproof ESM should be applied
• The heating must then remain off for a further 48 hours (minimum) after completion of the installation, and when turned back on run at a maximum temperature of +27°C in accordance with BS 8203 and BS 5325

Cleaning:

• Mapeproof ESM can be cleaned from tools and clothing with ethyl alcohol while the product is still fresh

Safety Instructions

• Mapeproof ESM component A is irritant for the eyes and skin
• Both components A and B may cause sensitisation if they come into contact with the skin of those predisposed
• Mapeproof ESM component B is corrosive, may cause burns and damage to eyes
• The product contains low molecular weight epoxy resins that may cause sensitisation if crosscontamination occurs with other epoxy compounds
• During use, wear protective gloves and goggles and take the usual precautions for handling chemicals
• If the product comes in contact with the eyes or skin, wash immediately with plenty of water and seek medical attention
• Mapeproof ESM components A and B are also hazardous for aquatic life
• Do not dispose of these products in the environment
