Product description

POLYSEAL 600 is one component polyurethane sealing material.

 POLYSEAL 600 creates, after having hardened, a white, strong and flexible, abrasion resistant sealing membrane, with a smooth surface and nice aesthetic appearance.

 POLYSEAL 600 has an excellent resistance to external weathering (UV) conditions and is not sensitive to ponding water.

Application

POLYSEAL 600 is used as a top coat for Polyseal 400 polyurethane sealing system.

Instructions for use

Surface preparation

Check that gutters are in good working order, that walls and floor meeting corner sides are rounded, and verify minimum slopes of 1.5%.

Concrete substrate will be casted minimum 30 days before application.

Remove intensively all loose particles. Rinse intensively the roof/deck to remove mud and wait until completely dry.

Application temperatures: 7ºc - 35ºc (convenient temperatures: 15ºc - 27ºc).

Performing of the sealing system

  Waterproofing system for exposed roofs:

1. Apply POLYSEAL 400 in 2-3 layers, in total quantity of 1.50 - 3.00 kg/m², depend on slopes, type of substrate and roughness conditions, dimensions of the roof. Drying time between layers: 3-5 hours.

For long term and qualified roofing system :

On substrates such as concrete, old bitumen membranes with aggregates, old PU and acrylic coatings - apply Aquapoxy, 250 gm/m², wait 1-2 hours for initial drying.

On metal substrate, apply Polyseal Primer, 150 gm/m², wait 3-4 hours for initial drying.

1. Apply POLYSEAL 400 in 3 layers, in total quantity of 3.00 kg/m² (1.6 mm dry). Drying time between layers: 3-5 hours.
2.  Apply Polyseal 600 (aliphatic polyurethane) as a top coat, in quantity of 200 gm/m².
3. In case the roof area is bigger than 10 m², sink a polyester net type Polyfabric into fresh POLYSEAL 400 of the first layer. Less qualified alternative is using glass net for this purpose.
4.  In tiled roofs, apply 3.0 kg/m² of   POLYSEAL 400, in 3 layers, on top of Aquapoxy. In case the roof area is bigger than 10 m², apply polyester fabric as mentioned above.

On rough surfaces, you should expect bigger quantities.

Drying time

To touch: 12 hours (at 25°C and 50% humidity).

Final drying time: 5 days.

Storage

In the shade, protected from high temperatures (5°C – 35°C)

Packaging

20 kg (18 litter metal pail), 5 kg gallon
