Asfredol^® 2000

Asfredol 2000 is a special bituminous emulsion based on special emulsifying agents and synthetic resins which improve the flexibility and mechanical properties of the dried bitumen film. It is ideal for the waterproofing of foundations, basements, tanks, basins, etc. whose size and mobility require treatments with greater flexibility. Asfredol 2000 adheres perfectly to wood, cement, fiber cement, brick, asphalt and felt and can be applied both indoors and outdoors on horizontal and vertical surfaces without dripping. Asfredol 2000 is highly resistant to acid and alkaline solutions, vapours, smoke, gas, etc. Due to its polymer modification, one hardened layer of Asfredol 2000 is more flexible and has better adhesion compared to normal bituminous emulsions.

Instructions for use

Preparation for use
The surfaces to be treated must be clean and free of dust.

Product preparation
Mix the product before use.

Instructions for use
Asfredol 2000 is applied cold using a brush, roller, spatula or trowel. It can also be sprayed on. Asfredol 2000 can be used to waterproof foundations against moisture in the ground (DIN 18195-4) or as internal lining of concrete tanks.

Important: Asfredol 2000 must always be applied on the side exposed to the water (positive pressure waterproofing) and never on the opposite side (negative pressure waterproofing). The surface must be smooth, clean and cohesive, but can be slightly damp.
– Waterproofing of foundations: Asfredol 2000 can be used to waterproof foundations against moisture in the ground (DIN 18195-4). Due to its simplicity of use, Asfredol 2000 is widely used to waterproof foundations against ground moisture and non-accumulating seepage water (DIN 18195-4 “Waterproofing against ground moisture”). Asfredol 2000 is applied cold on clean and dust-free surfaces. The first coat of Asfredol 2000 is diluted with two parts water and is applied with a paint brush or a long-handled scrubbing brush. This preliminary coat will penetrate into the pores and prepare the substrate for the application of at least two coats of undiluted Asfredol 2000. Coverage: approximately 2 kg per m².
– Internal lining of concrete tanks: Asfredol 2000 is completely odourless, is highly stable and once dry it leaves a film of bitumen which will not re-emulsify, even in continuous contact with water. It is therefore ideal for the waterproofing of concrete tanks and basins. Application is easy. For the first coat Asfredol 2000 should be diluted with 2 parts of water, this ensures the perfect adhesion of the subsequent coats of undiluted Asfredol 2000. It can be applied using a paint brush, a long-handled scrubbing brush or a spatula. Apply at least two coats. As soon as the bitumen dispersion has dried, the treated tanks and basins can be filled. Not to be used for drinking water tanks. Coverage: Approximately 1 kg per m².

Asfredol 2000 should always be mixed before use. To improve penetration and to help the adherence of subsequent coats, the first coat should be diluted with water. The dilution ratio depends on the absorption of the substrate and can vary from 1:1 to 1:6. Subsequent coats are to be applied as is.
For the bonding of insulating panels, to obtain thicker coats or to accelerate the drying reaction, cement or a mixture of sand and cement can be added to the Asfredol 2000. To avoid making the mass excessively thick, do not exceed 5% by weight of cement compared to the Asfredol 2000 (20 kg of Asfredol 2000, plus 1 kg of cement). The amount of sand to be added depends on the particle size of the sand and on the thickness to be obtained. A 2:1 mixture of sand to cement is normally used.

Storage

When stored in a cool, dry place in its original sealed packaging Asfredol 2000 is stable for at least 12 months. PROTECT FROM FROST.

Warnings

• It is recommended to apply the product at an ambient temperature not lower than +5°C and when there are no fog, rain or frost conditions, avoiding extreme cold and heat.
• Apply the product on the side of the product exposed to water (positive pressure water stress).
• Do not use to coat surfaces in contact with drinking water.
• Do not apply on very hot substrates as this would adversely affect the cohesion and adhesion of the product to the substrate.
• On highly absorbent surfaces it is advisable to apply a first coat of Asfredol 2000 diluted with water (see application instructions).
