Mapei Adesilex P4 extended information

CONSUMPTION
Flooring installations

  • Medium size tiles on smooth surfaces (with No. 6 or No. 10 trowel): approx. 3-5 kg/m2.
  • Large tiles or uneven surfaces (No. 10 trowel or Adesilex P4 trowel): approx. 5-10 kg/ m2.

Mapei Adesilex P4 is a grey powder composed of cement and fine-graded mineral fillers, containing high quantities of synthetic resins and special additives according to a formula developed in the MAPEI Research Laboratories.

Mixed with water, Adesilex P4 becomes a mortar with the following properties:

  • semi-fluid and easily trowellable;
  • 100% back-buttering is guaranteed. With Adesilex P4 it is possible to obtain adhesive beds 3 mm to 20
    mm thick without undulations, ideal for external installations and heavy traffic areas;
  • able to absorb deflections of the substrate and tiles;
  • perfect bonding to all materials generally used in building;
  • cures rapidly without significant shrinkage until it builds a sufficient bond strength;
  • waterproof, weatherproof and resistant to frost.

RECOMMENDATIONS

Do not use Mapei Adesilex P4:

  • on walls or slanted surfaces;
  • wood and wood conglomerates;
  • metal surfaces, rubber, PVC or linoleum;
  • with natural or artificial stone material slabs subject to movement due to moisture.

 

APPLICATION PROCEDURE

FLOOR INSTALLATION

Preparing the substrate
The substrate must be cured, mechanically strong, free of loose materials, grease, oils, paint, wax and sufficiently dry.
Cementitious substrates should not be subject to shrinkage after the installation of ceramic tiles. During spring and summer, the cementitious screeds must be cured for at least 28 days, unless they are not made with MAPEI special binders for screeds, such as Mapecem, Mapei Topcem or with Mapecem Pronto, Topcem Pronto. Dampen with water to cool the surfaces that have been heated by the exposure to sunlight. Gypsum substrates and anhydrite screeds must be perfectly clean, sufficiently hard and free of dust. It is absolutely essential to treat them with Mapei Primer G or Mapeprim SP. Areas subject to high humidity must be treated with Primer S.

Preparing the mix

Mix Mapei Adesilex P4 in a clean receptacle with 5-5.5 litres of clean water for every 25 kg bag until a smooth lump-free paste is obtained. Let the mix sit for 3 minutes, then stir again, and the mix is ready for use. Mixed this way Mapei Adesilex P4 will have a pot life of approx. 60 minutes at +23°C and 50% R.H.
If both adhesive and tiles are very thick, or the tiles are particularly heavy, 20% of suitably graded clean sand may be added to prevent shrinkage or settling.

Applying the mix

Apply Mapei Adesilex P4 to the substrate with a suitable trowel.
The selection of the correct trowel depends on the evenness of the substrate, the size of the tile and the profile of the back.

For flat surfaces and medium size tiles use MAPEI trowel No. 6 or No. 10 (consumption approx. 3-5 kg/m2).
For uneven surfaces, large size tiles, tiles with highly profiled ribs or lugs, MAPEI trowel No. 10 or a round-notched trowel is recommended (consumption approx. 5-10 kg/m2).
Consumption is generally 1.4 kg/m2 for each mm of thickness.

Installing the tiles

It is not necessary to wet the tiles before setting. Only when the backs are very dusty is it advisable to dip the tiles in clean water. Set the tiles on the bed of Mapei Adesilex P4 without pressure but with a light hand movement to ensure 100% coverage.

The open time of Mapei Adesilex P4 in normal temperatures and humidity is approx. 15 minutes. Unfavourable weather conditions (strong sun, wind, high temperature) may shorten the open time, sometimes quite drastically, to just a few minutes.

For this reason, constant checks must be made to see if the adhesive has formed a surface skin or is still “fresh” to the touch. Wetting the substrate before applying the adhesive helps to lengthen the open time. However if a surface skin has formed, retrowel the adhesive with a notched trowel. It is not advisable to wet the adhesive once it has formed a skin because, instead of dissolving the skin, a non-adhesive film will be formed.

Any necessary adjustment of the tiles should be carried out within 30 minutes after setting, after which time adjustment becomes problematic.

Tiles set with Mapei Adesilex P4 must not be subject to washout or rain for 3 hours at a temperature of +23°C and must be protected from frost and hot sun for at least 24 hours after installing.

GROUTING AND SEALING

Joints between the tiles can be grouted after 4 hours with the specific MAPEI cementitious or epoxy grouts, available in different colours. Expansion joints must be sealed with the specific MAPEI sealants.

SET TO LIGHT FOOT TRAFFIC

Floors are set to light foot traffic after approximately 4 hours.

READY FOR USE

The surfaces are ready for use after approx. 24 hours.

SMOOTHING

Preparing the substrate
Substrates must be level, solid, consistent and free of loose materials, grease, oils, paint, wax, etc. and sufficiently dry. Anhydrite substrates must be thoroughly dry, sufficiently hard and free of dust (check for residual moisture) and must be previously treated with Mapei Primer G.
Substrates in very damp areas must first be treated with Primer S or Mapeprim SP.

Preparing the mix

Mix Mapei Adesilex P4 in a clean receptacle with 5-5.5 litres of clean water for every 25 kg bag until a smooth lump-free paste is obtained. Let the mix sit for 3 minutes, then stir again and the mix is ready for use. Mixed this way Mapei Adesilex P4 will have a pot life of approx. 60 minutes at +23°C and 50% R.H.

Applying the mix

Apply the mix with a long metal trowel. When needed, additional coats may be applied in rapid succession as soon as the previous coat has hardened.

Installing the tiles

The surface can be tiled over as soon as it has hardened (3 to 4 hours, depending on the temperature and the absorbency of the substrate).

BRICK AND CEMENT BLOCK WALLS

Preparing the mix
Mapei Adesilex P4 should be mixed in a clean receptacle with 5-5.5 litres of clean water for every 25 kg bag until a smooth lump-free mix is obtained. Let the mix sit for 3 minutes then stir again and the mix is ready for use. Mapei Adesilex P4 has a pot life of approx. 60 minutes at +23°C and 50% R.H.

Laying brick or concrete blocks

Pour the Mapei Adesilex P4 mix into a receptacle large enough for the size and shape of the brick or cement blocks.
Place the brick or concrete block on the surface of the mix so the adhesive is transferred.

Place the brick or block on the wall. This method cuts completion time by half.

Cleaning

Tools and hands may be cleaned with abundant water. Tiles may be cleaned with a damp sponge; only after a few hours may a little water be used.

Smoothing

Approx. 1.4 kg/m2 for each mm of thickness.

Brick and concrete block walls

As needed, depending on the size.

PACKAGING

Mapei Adesilex P4 is available in 25 kg paper bags.

STORAGE

12 months in a dry place in the original unopened packaging.
The product complies with the conditions of Annex XVII to Regulation (EC) N° 1907/2006 (REACH) – All. XVII, item 47.

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
