Description

Characteristics

Application

LITOLIV EXPRESS | Self-leveling composition, gray in color, based on hydraulic binders that promote quick drying, inert silica, limestone of the best granulometry and organic additives.

ADVANTAGES

Excellent ability to self-align;

Easy application;

High bending and compressive strength after only 4 hours;

Quick drying;

Absence of shrinkage during drying;

Very low release of volatile organic compounds.

FIELD OF APPLICATION

It is intended for leveling internal, horizontal bases, with a layer of 3 to 40 mm, in residential buildings and commercial premises (offices, stores), where intensive surface loads are not provided.

Recommended bases:

cement screeds made by Litocem or Litocem Pronto;

warm floors (electric and water);

anhydrite (gypsum) screeds;

existing coatings made of ceramics, natural stone or marble chips;

concrete slabs.

FOUNDATIONS

The bases must be clean, dry, strong, dense, sufficiently durable, without removable parts and protected from rising moisture;

Any cracks or chips must be repaired: moisten the surface with Decor Primer Fondo primer and immediately sprinkle with dry sand or quartz with a particle size of 0.4 to 1 mm.

Preparation is based

Porous, highly absorbent and dusty bases must be pre-treated with Primer C, which closes the pores of the base and promotes better spreading and self-leveling of the product;

Dense and smooth surfaces (concrete, old ceramic tiles, marble chips) should first be degreased with a 10% solution of caustic soda or alkaline detergents, and then treated with the Prepara Fondo primer;

Anhydrite, gypsum screeds must be pre-polished and primed with Primer C or Primer X94;
It is necessary to measure the maximum moisture content with a carbide hygrometer, the indicator should not exceed 0.5%.

COMPENSATION SEAMS

It is necessary to provide compensatory seams to divide the continuity of the lined surface;

As a rule, they should be performed in rooms with an area of 50 m2 or 25-30 m2, in the case of a warm floor;
In rooms with an area of less than 50 m2, it is possible to perform a seam only at the door joints.

PREPARATION OF THE SOLUTION

Dilution ratio: 4.4 - 4.8 liters (22-24%) of water per 20 kg (1 bag) Litoliv Express;

To obtain a solution, you should slowly pour the powder into water with constant stirring at low speeds, using an electric drill with a mixer nozzle to obtain a homogeneous, lump-free solution.

Attention! Keep the resulting solution for 3 minutes;
After re-mixing, the solution is ready for use.

The life time of the finished solution is about 30 minutes, so it is recommended to mix the amount of material that will be used in this period of time;

If the composition is applied with a plaster pump from a construction mixer, then the amount of water should be the same as with manual preparation.

APPLICATION

The solution is poured directly onto the base and distributed over the surface with a smooth spatula or squeegee, forming a layer of the required thickness;
It is recommended to roll the surface of the solution with a needle roller for better spreading and removal of air bubbles.

The solution can also be applied by machine.

LAYING TILE

The subsequent installation of tiles, stone, parquet, soft and woven floor coverings can be started after 24 hours;

When laying the parquet, the thickness of the Litoliv Express layer should be at least 3 mm.

Recommended glue

For laying ceramic tiles, porcelain stoneware, clinker and cotto: cement adhesive mixtures of class C2 – C2F;

For natural and artificial stone: Litostone K99, Litoflott K88, Litoelastic.

Compatible waterproofing materials:

Waterproofing can be performed with Elastocem, Coverflex or Hidroflex materials, which are applied 24 hours after pouring Litoliv Express and 24 hours before laying the ceramic material.

ATTENTION

Do not add lime or cement to the product;

Does not apply to bases exposed to the effect of rising moisture;

Apply at temperatures from +5 to +35 °C;

Observe the specified amount of water for preparing the solution;
An excess of water can lead to an increase in the setting time, the possible formation of cracks, chips or a loose surface;

In a hot climate, store the package in a cool place, protected from the sun;

Pretreatment of the Primer C surface improves the adhesion of the leveling layer and facilitates the application of the product due to the uniform absorption of the base;
