SILICONE HYDROPHOBIC AGENT FOR PROTECTION OF ABSORPTIVE SUBSTRATES
FOR INTERNAL AND EXTERNAL USE

USE

AVAL KT 98 is designed for hydrophobisation and protection of absorptive stone elements, substrates made of ceramic (e.g. brick walls) and lime-sand materials, concrete and mineral plasters from adverse effect of external environment. It is perfect for priming substrate under silicone paints. It can also be used for hydrophobisation of old façade paint coats tightly adhering to the substrate and thin-layer mineral and acrylic plasters. It is suitable for internal and external use.

PROPERTIES

AVAL KT 98 is a colourless solution of silicone dispersion in an organic solvent. After application, it reacts with components of air and with water in pores of the construction material. This reaction reduces absorptive degree of the primed material; therefore the protected surface is not contaminated easily and precipitation water runs down freely on the surface providing additional cleaning. AVAL KT 98 penetrates the material, at the same time providing great permeability of water vapour. It is resistant to alkalis, acid rain, UV radiation, aggressive urban environment and temperatures from –20°C to +80°C.

SUBSTRATE PREPARATION

The substrate should be dry, structurally sound and free from dust, dirt, oil, fat and wax.

PRODUCT PREPARATION

AVAL KT 98 is a ready-to–use emulsion. It may not be combined with other materials, diluted or thickened.

APPLICATION

Apply the undiluted emulsion over the substrate with a roller or paintbrush. Application of another layer (on very absorptive substrates) or painting, e.g. AVAL KT 48 silicone paint, can be started when the first layer has completely dried i.e. after 6 hours. Do not use the agent on substrates layers of which (at the depth of agent penetration) contain materials not resistant to organic dissolvent e.g. foamed polystyrene located under the reinforcing layer of the External Wall Insulation system. During work and afterwards, always ensure sufficient ventilation until the characteristic smell disappears. Do not leave open containers. The information comprises basic instructions of product application and do not relieve users of responsibility for work in accordance with good construction practice and OHS regulations.

CONSUMPTION

On average, 0.1÷0.3 l of preparation is used for 1 m2. In practice, consumption depends on the type of substrate and how absorptive it is.

TOOLS

Brush, paint roller. Wash the tools with clean water and detergent directly after use.

PACKAGING

Metal containers: 1 l, 5 l

STORAGE & TRANSPORT

Transport and keep the agent dry in tightly closed original packaging, in positive temperatures above from +5°C to +25°C. Avoid overheating. Observe OHS regulations regarding storage applicable for solvent paints, complying with requirements of flammable material storage. Shelf life is 12 months from the production date on the packaging.

CAUTION

Harmful and flammable. Protect skin and eyes. Keep away from the reach of children. In case of contact with eyes, immediately rinse with plenty of water and seek medical attention. In case of direct contact with skin, rinse affected places with plenty of water with soap. In case of ingestion, do not induce vomiting, immediately seek medical attention and show the packaging or label. Ensure no agent enters drains and dispose of waste from residues and packaging in a safe manner.
