Product Overview: Neoproof PU360 – Water-Based Polyurethane Waterproofing Coating

Neoproof PU360 is a water-based modified polyurethane elastomeric waterproofing coating designed for non-exposed applications on both horizontal and vertical construction surfaces. This versatile coating is suitable for use before plastering, tiling, laying of cementitious screeds, mortars, and the installation of insulation and soundproofing panels.

Packing:

Available in 13kg and 4kg packaging.

Colors:

White RAL 9003 (Also available in black and other shades upon request).

Fields of Application:

Under tiles in wet rooms (bathrooms, kitchens, etc.), terraces, and roofs.
On drywall panels before plastering, tiling, etc.
Roofs and walls, prior to the installation of insulation and soundproofing panels.

Properties/Advantages:

Highly resistant to ponding water and alkalis of the cement.
Increased resistance to bending and stretching.
Excellent compatibility with subsequent cementitious layers (tile adhesives, cement screeds, etc.).
High adhesion and crack-bridging properties.
Fast-drying.
Applicable on various construction surfaces (concrete, plaster, metal, wood, etc.).
Eco-friendly (does not contain solvents or bitumen) and user-friendly (water-based, one-component).

Appropriate Primers on Usual Substrates:

Concrete, Cement Screed: Revinex® (diluted with water 1:4)
Metal (Iron, Steel): Neotex® Metal Primer
Inox, Galvanized Steel, Aluminium: Neotex® Inox Primer

Instructions for Use:

Substrate Preparation:

Ensure the surface is stable, clean, dry, and free of dust, oil, grease, and loose materials.
Remove poorly adhering materials and older coatings.
Mechanical or chemical cleaning may be required.
Smooth irregularities and create optimal conditions for adhesion.

Priming:

Apply the appropriate NEOTEX® primer before the application of Neoproof® PU360.
For cementitious substrates, consider Revinex® diluted with water, Silatex® Primer, or Vinyfix® Primer.

Application:

After priming, apply Neoproof® PU360 in at least two layers by roller, brush, or airless spray.
The first layer is diluted 5% with clean water, while subsequent layers are applied undiluted.
Apply each layer in a vertical or different direction than the previous one.

Special Notes:

Do not apply under wet conditions or if rain is expected during application or curing.
Ensure substrate temperature during application and curing is at least 3°C above dew point.
In areas requiring tiles, plastering, etc., broadcast quartz sand during the application of the final layer for enhanced adhesion.
After Neoproof® PU360 hardens, remove any loose grains with a high suction vacuum cleaner.
Use an elastic tile adhesive for tiling (e.g., type C2TE S1).
Reinforce with Neotextile® in areas prone to stagnant water.
