Description



Avipast

Specifications

Avipast is a water-based material. It does not stink of, it is not inflammable and it does not contain any scented dissolvers. It is used for protecting concrete, mortar, brick constructions, even if they are wet.

Usage

When AVIPAST has become mature, it makes an indissoluble coat that cannot be affected by acid and alkaline solutions. Its excellent adhesion and its easy application establish it as the most appropriate product for a wide variety of usages, especially for watertighting substructures, floors, inclined roofs and for repairing lofts, etc. You can also use it in combination with concrete and sand; in this case it creates a plastic mortar, with excellent mechanical resistance, which can be applied on industrial floors, gymnasium floors, etc.

Application

Avipast must be applied at least twice on each surface (bedding). Vertical Surfaces: For the first application you have to thin out Avipast with 1/2 water. Then it can be brushed. After the surface dries out (depending on the temperature, the substratum and the ventilation) thin out Avipast with 1/4 water and proceed on the second application. Horizontal Passable Surfaces: In cases like this Avipast can be combined with glass paper or/and burlap, so it creates an in situ bitumen fabric without joint gaps. You can also thin out Avipast with 1/2 water for the first application and with 1/4 water for the second application under the condition that it takes two applications per reinforcement. Avipast can also be applied with airless.

Consumption

The consumption depends on the amount of the absorption and the structure of the surface. Vertical surfaces 0.6-1 kg/m2 is required for two spreads. Horizontal Non-Passable surfaces: 2-3 kg/m2 is required for two spreads. Horizontal Passable surfaces: 3.5-4 kg/m2 is required (using reinforcement).

Comments

Before its application it is recommended that the surface is clear and free from rotten materials. If the asphaltic emulsion dries out it can be dissolved with benzene. Do not apply Avipast if the temperature is under 0o C or under the sun exposition, rain (not even if it is assumed that it is about to rain within 10 hours before its application). Avipast becomes watertight just after it dries out. In order to accelerate this procedure you can use 0,3% cement.

Safety

In contact with eyes, wash it out with water.

Hands can be purified with water and soap. IRRITANT

For additional info ask the (M.S.D.S.) of this material from the producer.

Ecology

In liquid form Avipast contaminates the water. Do not pour it on the ground. Always follow the related rules.

Toxicity

None.

Package

Avipast is disposable in dispensers of 18 kg and in drums of 200, 220 kg.
