LITOKOL AQUAMASTER EVO – 20kg

 

GENERAL

Aquamaster EVO is a fibre-reinforced ready-to-use liquid membrane made from synthetic resins in aqueous dispersion, solvent-free, used for the waterproofing of indoor and outdoor wet areas.
Does not require reinforcing mesh or fabric and sealing bands to protect the corners and edges of the waterproofing system.
Can be overlaid on non-absorbent materials such as existing ceramic and porcelain tiles.

 

TECHNICAL

LITOKOL AQUAMASTER EVO IS FIBRE-REINFORCED READY-TO-USE LIQUID MEMBRANE IN AQUEOUS DISPERSION, ELASTIC, CHLORINE- RESISTANT, FOR WATERPROOFING OF INDOOR AND OUTDOOR WET AREAS IN CLASS DM 02P ACCORDING TO UNI EN 14891. PRODUCT WITH VERY LOW VOLATILE ORGANIC COMPOUND EMISSION RATE.

 

ADVANTAGES AND FEATURES

Litokol Aquamaster EVO:
Product with very low volatile organic compound (VOC) emission rate. Complies with class EC1PLUS according to the EMICODE protocol and class A+ (Émission dans l’air intérieur – French Regulations)
Single component ready-to-use product that does not require any preparation
Unlike other waterproofing membranes, it does not require reinforcing mesh or fabric and sealing bands for the protection of corners, making installation faster and more affordable
Applicable with smooth steel trowel, roller or brush
Reusable product. Any leftover material, if stored in the original packaging at temperatures between +5°C and +35°C, can be reused even after months, thus avoiding wastage
The fast drying time allows the application of multiple coats just a short time apart, making it possible to complete waterproofing in one day only
Coverings can be installed just 24 hours after the application of the last coat with cementitious adhesives in class C2 or reactive adhesives in class R2 according to EN 12004
Product exempt from restrictions for road, sea, air and rail transport
Fibre-reinforced for maximum elasticity and resistance, even at low temperatures

 

FIELDS OF APPLICATION

Intended uses:
Interiors – exteriors
Floors and walls
Underfloor heating
SPA and Hammam
Terraces and balconies
Indoor wet areas (bathrooms, shower enclosures) Residential, public, commercial building
Industrial floors
Tanks, swimming pools, fountains

Suitable substrates:
Cement screeds
Self-levellers
Cement levellers
Existing tiles
Gypsum
Concrete
Fibre cement slabs
Gypsum-based plasters
Aerated concrete
Cement plasters
Wood panels, type CTBH
Underfloor heating systems
Lightweight panels (such as WEDI-SCHLUETER).

 

PRE-INSTALLATION

The substrates must be clean, solid, compact, crack-free, properly cured and without rising damp.
If the substrate is not perfectly flat or the level is incorrect, it can be evened before installation using suitable levelling or self-levelling products, for example Litoliv S40 Eco, Litoliv Extra 15, Litoliv Express or Litoplan Smart.
In the case of surfaces exposed to frequent wetting such as balconies, terraces, shower floors, etc., check that the slopes and dimensioning of the drain systems are adequate to allow the proper outflow of water considering the width of the exposed surface and maximum expected wet conditions. Generally, a slope of 1-1.5% is sufficient to guarantee the correct outflow of water. Cementitious substrates can be evened or sloped using the Litoplan Smart rapid skim coat.

Use of primer:
• In the case of substrates that are not perfectly smooth such as screeds and cementitious levelling layers or those
created with Litoplan Smart, and lightweight panels finished with a reinforced cementitious levelling layer, apply the first coat of Aquamaster EVO with a roller or brush, diluted with 10% water, making sure it properly penetrates the substrate. This will close the surface pores of the substrate, thus preventing the emergence of bubbles when the subsequent coats are applied
• In the case of anhydrite screeds, check for the presence of a suitable vapour barrier in order to prevent rising damp. Use a carbide method hygrometer to check that the residual humidity is less than 0.5%. The surface must be sanded and treated with Primer C
• Any cracks must be repaired with Multifondo EVO, sprinkling the fresh surface with sand or dried quartz with granulometry 0.4-1 mm
In any case, the respective technical data sheets must be consulted for correct use of the indicated products.

 

MIX RATIO

Litokol Aquamaster EVO is a ready-to-use product without the need for any preparation.
In any case, once the container has been opened, we recommend mixing the product briefly, even manually, with a steel trowel or spatula.

 

APPLICATION

Apply Litokol Aquamaster EVO directly onto the substrate using a smooth steel trowel, roller or brush. Apply two/three consecutive coats so that the final thickness of the dried material is at least 0.8-1 mm.
In the case of substrates that are not perfectly smooth such as screeds and cementitious levelling layers or those created with Litoplan Smart, and lightweight panels finished with a reinforced cementitious levelling layer, apply the first coat of product with a roller or brush, diluted with 10% water, making sure it properly penetrates the substrate. This will close the surface pores of the substrate, thus preventing the emergence of bubbles when the subsequent coats are applied.
After the drying time (approx. 30 minutes at a temperature of +23°C), apply the subsequent coats of undiluted product.
The open time between the second and third coat is approximately 4 hours at a temperature of +23°C.
Use utmost caution when applying the product in edges and corners, making sure not to leave any excess material that may cause cracking during the drying phase.
In the presence of pipework, drains, spotlights, etc., lay the special Litoband SK Pipes Collar and Litoband SK Self- Adhesive Drains Collar pieces.
Alternatively:
For the sealing of pipework and through-elements in general with irregular sizes and/or shapes, create a connecting bead between the element and the waterproof membrane with the ready-to-use adhesive grout Litosil MS.
For correct use of the products to be used, always refer to the respective technical data sheets.

 

TILE INSTALLATION

Coverings can be installed after at least 24 hours have passed since the last coat.
Ceramics, natural stones or mosaics can be installed with cementitious adhesives in class C2 or reactive in class R2 according to UNI EN 12004.
The choice of adhesive depends on the size of the tiles and expected operating conditions.
In the case of large tiles (side > 60 cm), it is preferable to use deformable adhesives in class S1 or highly deformable adhesives in class S2.
The tiles must be installed with a solid bed using the back-buttering technique, with joint widths suited to their size. For the correct choice of adhesive, refer to the technical data sheets of the products.

 

WARNINGS

• Spread the product at temperatures between +5°C and +35°C inclusive
• Do not add lime, cement or other foreign materials to the product
• Do not use the product on plastic, resilient, metal materials or resin-treated substrates
• Do not spread the product with thickness > 1 mm per coat
