Product description:

White powder of special cements, easily redispersible resins, selected fillers and special additives.

The powder is mixed with water until a homogeneous, lump-free putty is obtained which is easy to fill and can be used for approx. 15 minutes.

The mortar dries in 30-45 minutes on absorbent substrates and in 60 minutes on non-absorbent substrates. Laying of any type of lightweight flooring is possible after 60 minutes.

The dry layers have low stresses and are permeable to water vapour.

Substrate preparation:

ARDEX R4 adheres on almost any type of substrate, these must be dry, firm, load-bearing and free of dust, dirt and other disintegrating agents.

Old, poorly adhering and poorly bonded paints, as well as loose plaster and wallpaper must be removed.

Valid substrates:

• - Concrete.
• - Cement and lime cement plaster.
• - Gypsum plaster and plasterboard.
• - Masonry.
• - Decorative mineral plaster.
• - Gypsum boards with fibres.
• - Ceramic tiles and coverings.
• - Wash-resistant dispersion paints:
• - Antique latex-based paints.
• - Alkyd paints.
• - Acrylic lacquer paints.
• - Fibre-reinforced wallpapers.
• - Existing substrates with adhesive residues and well-adhered self-levelling compounds.
• - Pressed wood panels.
• - Natural stone and terrazzo.
• - Wooden slabs and stairs.
• - Dry screeds.

Instructions for use:

Pour clear water into a clean mixing container, add the powder and beat vigorously until a homogeneous, creamy mixture is obtained.

Approx. 0.4 litres of water is required to mix with 1 kg of ARDEX R4 powder.

Only the material that can be used for 15 minutes should be prepared.

The mortar can be used for approx. 15 minutes (+20°C) and can be applied immediately in the desired layer thickness up to a maximum of 10 mm.

The mortar layer is scraped off by pressing hard with the trowel to achieve a sufficiently smooth surface for most applications. A subsequent smoothing with a slightly damp sponge can be carried out for approx. 30-45 minutes in order to achieve particularly smooth surfaces.

Higher temperatures reduce setting and post-treatment times, lower temperatures lengthen them.

On non-absorbent substrates a minimum thickness of 1 mm should be applied.

In case of doubt, test surfaces.

ARDEX R4 should be used at temperatures above +5°C and below +30°C.

Important note:

ARDEX R4 must not be used in permanently wet areas.

Warning:

Contains cement. Reacts alkaline. Therefore skin and eyes should be protected.

In case of contact, rinse thoroughly with water. In case of contact with eyes, additionally consult a doctor.

When set, it is physiologically and ecologically harmless.
