Levelling and subsequent laying of ceramic flooring

System description

For the correct installation of a thin-bed ceramic floor tile, it is necessary to have a substrate in good condition and with an adequate planimetry. The solution consists of using NIVELANTE 10, NIVELANTE 80 or BETOLEVEL® 15, self-levelling mortars that set quickly, have excellent adhesion and are very hard, allowing the substrate to be easily, quickly and safely screeded and prepared prior to laying the ceramic tiles.

Solution

PREPARATION OF THE SUBSTRATE

Check the state of the substrate, it must be resistant and completely set and free of dust, paint, oils, etc…

Check existing differences in flatness, choosing the material best suited to these differences.

Repair all small holes and degraded areas with the same levelling mortar NIVELANTE 10, NIVELANTE 80 or BETOLEVEL® 15, or with PROPAM® REPAR 5, PROPAM® REPAR 40 or PROPAM® REPAR TECHNO if the substrate is concrete. To prepare the substrate with a primer prior to the application of NIVELANTE 10, NIVELANTE 80 or BETOLEVEL® 15:

• Porous substrates: PROPAM® PRIMER SOL.
• Non-porous substrates: PROPAM® GRIP +.

Respect expansion and contraction joints.

APPLICATION

Knead NIVELANTE 10, NIVELANTE 80 or BETOLEVEL® 15 with a slow electric mixer (500 rpm), leave to stand for 2 minutes and mix again to have the paste ready for use.

Pour NIVELANTE 10, NIVELANTE 80 or BETOLEVEL® 15 on the substrate and spread with a trowel to facilitate levelling.Use a spiked roller to deaerate the mixture and to facilitate levelling.

If a second coat is to be applied, it must be applied as soon as the first coat can be walked on (approx. 4 hours).

As a general rule, wait 24 hours before covering with ceramic.

Recommendations

• Do not apply on soils with permanent moisture or susceptible to capillary rising.
• Apply between + 5ºC and + 35ºC temperature.
• In order to apply a second coat, the first coat must not be completely dry, if this is the case, it is necessary to prime with PROPAM® GRIP +.
• It is recommended to use PROPAM® DUR as a consolidating agent for old mortars and concretes, before applying the product, waiting 12 hours for it to dry.
• Respect the mixing water and mix the product correctly, avoiding the introduction of too much air.
• The maximum thickness per coat indicated for NIVELANTE 10 is 10 mm and for BETOLEVEL® 15 15 mm.
• Use NIVELANTE 80 for thick levelling (up to 100 mm).
• In specific cases of rapid tile installation or for the installation of large format ceramics, use VAT® FLEX RAPID (C2FTES1) or VAT® SUPERFLEX RAPID (C2FTES2), cementitious adhesives with rapid setting, high adhesion capacity and deformable or very deformable respectively, to minimise the stresses that may be transmitted to the ceramic tile due to the immaturity of the substrate.
• On substrates with radial heating, turn off the heating 24 hours before application.
