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.


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.

GISCODE ZP 1 = product with cement content, low in chromate.
