abe® PU liquid rubber

Grey / White

All surfaces to be clean, dry, sound and free of all laitance, grease, oil or loose and flaking particles.

Concrete:

All new concrete slabs must be allowed to cure for at least 6 weeks. Old concrete must be cleaned with a strong commercial grade detergent or degreaser, then thoroughly wash off all residue with clean water. Allow the surface to dry for at least 24 hours.

Render:

Newly rendered surfaces must be allowed to cure for at least 7 days.

Lightweight Blocks: 

Prime the surfaces with abe^® proof acrylic primer prior to applying abe^® proof PU liquid rubber.

Metal Surfaces:

All metal surfaces must be totally free of rust. Prime metal surfaces with an etch primer.

Old waterproofing (liquid or membrane): 

Any surface to be coated should be Clean and Mechanically Sound.

Previously painted systems must be scrubbed using copious quantities of clean water.

Conditioned bitumen surfaces

Ageing of the bitumen yields considerable quantity of water soluble dust derived from the oxidisation process of the bitumen surface.

This water soluble dust must be washed off the immediate surface by scrubbing and using copious quantities of clean water.

Cracks: 

Hairline cracks up to 1mm wide which experience no movement, may be duly filled up with abe^® proof PU liquid rubber before applying another layer over the area to be waterproofed.

Static cracks that have no movement must be opened up and sealed with flexothane 1 and a polypropylene tape securely placed over the sealed crack. abe^® proof PU liquid rubber should then be applied over the area and on the tape and allowed to cure.

Drain Application: 

Treat the inside and around the drain with a separate layer of abe^® proof PU liquid rubber proceeding with the actual application of the whole surface area.

Do not allow the product to freeze.

Do not apply if the temperature is in excess of 45 °C or less than 5 °C.

Delay external applications when inclement weather is imminent.

Do not thin abe^® PU liquid rubber, as it is supplied ready for use.

Ponding should be avoided at least 48 hours after the final application of abe^® proof PU liquid rubber.

Use abe.^®proof acrylic primer for priming porous, substandard or bitumen impregnated substrates or membranes. Please consult relevant technical data sheet for details.

Stir well before use.

All surfaces to be treated must be as clean and dry as possible. It may be necessary to abrade areas where dirt or scale cannot be removed with a stiff broom.
Check the surface for cracks, splits, flashing, coverings, etc. abe^® PU liquid rubber should be applied in two coats directly from the pail.
Apply 1^st coat of abe^® PU liquid rubber to the whole area and allow to cure, approx. 2-4 hours. (temperature dependent)
Apply the 2^nd coat in a perpendicular direction to the 1^st coat.
abe^® PU liquid rubber can be applied by brush or roller.  Normally minimum of 2 coats is required.
NOTE: Reinforcement of corners with reinforcement netting where a 90º angle or greater is encountered is advised.

Recommended for per 5L pail:

7.5 – 11.5 m² per coat (about 0.35mm DFT ) or 3.75 – 5.75 m² per 2 coats.

TIP:  To ensure the recommended dry film thickness is achieved, pre-measure the area in sections to the recommended square meters.

Tools, brushes and mixing equipment should be cleaned immediately after use and before material has set with water.

Whilst abe^® PU liquid rubber is designed for an extended life, it is important to apply a maintenance coat every 5 years.

Note: Do not cover the final cured system with stones or stone chippings.

The waterproofing / flashing system will be abe.^®PU liquid rubber (5L), a single-pack, elastic water based PU compound applied in accordance with the recommendations of a.b.e.^® Construction Chemicals.

5L pail.

This product has a shelf life of 12 months if kept in a dry cool place in the original packaging. In more extreme conditions this period might be shortened.
