Mapei Mapeproof Primer One Component Rapid Drying PVDC Primer

One-component, rapid drying PVDC based dispersion primer for suppressing residual moisture up to 4.5 CM-% (95% R.H.)

Mapeproof Primer is a one component, ready to use system which dries rapidly to provide a waterproof surface membrane; it impedes the passage of residual construction moisture from affecting subsequent floor covering installations, therefore allowing early installation of floor coverings.

Product properties:

  • ready for use;
  • no mixing is required;
  • easy to apply by roller;
  • colour pigmented to aid coverage uniformity;
  • fast drying;
  • low consumption/high coverage;
  • no primer or sprinkling sand is required with subsequent levelling compounds;
  • complies with ASTM D 1308-87 standard for the resistance to urine;
  • can be resealed and stored with no particular precautions for future use;
  • not inflammable;
  • EMICODE EC1 Plus (very low emission);
  • Blauer Engel – DE-UZ 113.

You can add this product to your order, however there must be a pallet/half/three-quarter-pallet in the cart to checkout.

Mapei Mapeproof Primer

Coverage: 

Approx. 60-70 g/m2 with dilution 1:7.

Approx. 120-130 g/m2 undiluted, according to the absorbency of the substrate (approx. 250 g/mas a two coats application).

Mapeproof Primer is a one component, ready to use polyvinylidene chloride based dispersion primer which dries rapidly to provide a waterproof surface membrane.

Some application examples:

  • For damp-proofing cement based, moisture-resistant, non-heated substrates where residual moisture content values are up to 4.5 CM-%, before the application of levelling compounds.
  • For insulating residual construction moisture where relative humidity values are up to 95% R.H.
  • Suitable for use with heated screeds up to 85% R.H.

Recommendations

  • Apply Mapeproof Primer only on internal flooring.
  • Do not use over anhydrite or other gypsum/sulphate based substrates.
  • Use epoxy or polyurethane primer (such as Eco Prim PU 1K Turbo or Primer MF) on magnesium screed.
  • Do not use on substrates subject to rising damp.

Application Procedure

Preparation of the substrate

Substrates must be uniformly sound, free of dust, loose particles, cracks, paint, wax, oil, rust or other products that can interfere with bonding.

Screeds and concrete bases over base-ground must be provided with a structural damp proof membrane.

The residual moisture content of non-heated cement screeds must not exceed 4.5 CM-%.

Cracks have to be filled with a suitable product (such as Eporip, Eporip Turbo or Eporip SCR) before applying Mapei Mapeproof Primer.

Joints designed to allow movement of the substrate must not be bridged with Mapeproof Primer, but sealed with a suitable impervious flexible jointing compound after the application of the membrane.

The absorbency of the screed must be ensured. Compact substrates must be prepared mechanically

Application of the primer

Shake the can to mix the contents immediately prior to use. Mapeproof Primer must be applied in a minimum of two coats.

The floor temperature must be above +10°C when the primer is applied.

Mapei Mapeproof Primer should be applied over the whole floor.

With particularly low absorbent or finished screeds with a tight surface, first apply a dilute coat of Mapeproof Primer (1:1 with water) and allow to dry (approx. 20 mins). This will ensure that the Mapei Mapeproof Primer penetrates into the surface of the screed prior to applying the two coats of undiluted Mapeproof Primer.

1st Coat: Using a pre-coated roller apply the first coat in one direction ensuring that the material is worked well into the substrate.

2nd Coat: When the lst coat is touch dry, approximately 15-30 minutes at +20°C, apply the 2nd coat at a right angle to the Ist coat.

It is essential that a pin-hole free coating is achieved and to maintain a consumption of approx. 250 g/m as a two coat application (coverage: 4 m2/kg).

When applied to very absorbent surfaces, the membrane can be absorbed into the substrate leaving a subdued shine. In such instances or where pinholes and weak spots are evident, a further application will be required.

After complete drying of the primer, smoothing compounds from the MAPEl range can be applied. The drying times vary depending on the absorbency of the substrate and the room climatic conditions (temperature and humidity) between 2 and 5 hours.

Apply the appropriate MAPEl smoothing compound within 12 hours of the curing of Mapei Mapeproof Primer to provide an absorbent surface suitable for the application of adhesives.

If Mapeproof Primer is not covered within 12 hours of curing, a further coat must be applied and allowed to dry before proceeding with the application of the skimcoat.

Mapei Mapeproof Packaging

Mapeproof Primer is available in 10 kg cans.

Cleaning

While still wet, Mapeproof Primer can be cleaned from floors or wall coverings, tools, hands and clothing with water.

When dry, use alcohol or Pulicol 2000.

BTP very helpful in supplying a pallet of floor leveller. I needed it on the Saturday, but didn’t want it sitting on the driveway for several days. I called and they recommended ordering for Thursday to give a day’s grace in case of any delivery issues. In the event the pallet arrived on Thursday as requested. Reliable and good value
