Technical Information
Product Description

Uraprime W is a low viscosity solvent free primer based on Colmef Monneli’s heavy duty polyurethane resin binders. Monneli Uraprimer W is not designed for stand alone use and must be overlaid by the appropriate Uramassetto M1 coatings. The product comes in 3 components that need to be mixed completely using a suitable mixing paddle fited to a slow speed mixer (300-500 rpm) prior to application.

Advantages
  • Easily applied by brush and steel trowel.
  • Designed for highly porous surfaces
  • High wetting properties
  • Damp tolerant
  • Cost effective, suitable for use in MENA region conditions

Application Information
Instructions for use

It is essential  that  Uraprime W  is  applied  to a sound, clean and dry surface in order to achieve maximum bond strength between substrate and coating/repair products.

Priming

Mix Uraprime W as supplied. Mix thoroughly for about 2 minutes by electric drill with spiral mixing paddle. Once mixed, the Uraprime W shall be immediately applied in a thin continuous film using stiff brushes or rollers. Brush well into the sides and floor of the anchor grooves. Avoid over-application and puddles.

Uraprime W shall be allowed to become tack- free prior to the application of Polyurethane coating (unless otherwise specified) but well within the open time specified for the given temperature. The hotter the substrate, the more quickly the primer will become dry.

Curing

Uraprime W shall be allowed to become tack- free prior to the application of Polyurethane coating (unless otherwise specified) but well within the open time specified for the given temperature.

Defects in the primed surface, such as blow holes in the surface as a result out of bleed run pores in the substrate, should be remendied prior to overlaying. Failure to do so may lead to surface defects in the finished floor.

If the time between coats exceeds 48 hours, or if condensation or water impacts the surface, fully abrade the surface. This will normally mean that the floor must be reprimed.

Cleaning

All tools and equipment shall be cleaned immediately after use with water.

Surface Preparation

The surface should be at least 5 days old and visbly dry with no standing water. Laitence deposits on new concrete are best removed by light grit blasting, mechanical scabbling or grinding.

Where heavy contamination by oil and grease has occurred or existing coatings are present, it is essential that all contaminations are removed.

Additional Information
Health & Safety

Uraprime W is non-flammable. Refer to the Material Safety Data Sheet for further information.
