ELASTIC TOP

Anti-UV Elastic Waterproofing Bond Coat / Top Coat

Description

ELASTIC TOP is a compound of elastic copolymers with a wide molecular weight distribution range, dissolved in hydrocarbon, aliphatic and aromatic solvents, additives, pigments and inorganic fillers. Once fully cured, the film exhibits an excellent resistance to UV radiation, excellent adhesion to various types of substrates and good cold flexibility properties that maintains for a long period of time.

ELASTIC TOP is available in four standard colours: white, grey, red and green.

Usage field

ELASTIC TOP is used for the production of anti UV, elastic finishes on:

  • armoured waterproofing membranes;
  • sprayed polyurethane foam;
  • flexible substrates, even the metallic ones.
Packaging

5 and 20 kg metal drum.

Application

Mix thoroughly the contents of the bucket with a professional mixer prior to the application.

Allow 3-4 minutes for the mixed product to deaerate.

The product is slightly thixotropic (gel effect).

For any possible dilution and to clean up tools, only SOLVENTE PER ELASTIC TOP shall be used.

To old and non-reinforced membranes:

  • perform a thorough cleaning to remove dust and dirt;
  • apply a first coat with a roller on a dry surface, place the NYCON F armour on wet product and soak it to excess;
  • the next day apply ELASTIC TOP finish coat with a roller and ensure all pores of the armour of the first coat are fully saturated.

To old membranes with undamaged armour:

  • perform a thorough cleaning to remove dust and dirt;
  • apply on a dry surface, a first ELASTIC TOP coat with roller, brush or spray;
  • the next day apply a second coat to finish.

To old bituminous membranes with armour (rolled membranes):

  • perform a thorough cleaning to remove all dust, dirt and loose gravel;
  • apply to a dry surface a coat of FONDO IGRO SL (coverage: 100 g/m2) with a roller and, slightly broadcast on the still wet coat with quartz sand 0.1 to 0.6. In case of slated membranes, restrict broadcasting only to areas free of grits. However, apply a priming coat of FONDO IGRO SL to the entire surface.
  • The next day, apply to dry surface, a first coat of ELASTIC TOP with a roller, brush or spray.
  • The next day, apply the finish coat, making sure to saturate all the porosity of the armor.

To old waterproofing with cold asphalt (without armour):

  • perform a thorough cleaning to remove dust and dirt;
  • apply to a dry surface, a coat of FONDO IGRO SL with a roller (coverage: 100 g/m2) and lightly broadcast with quartz sand of size 0.1 - 0.6 mm;
  • The next day, remove any excess or loose quartz from the NYCON F armour and soak it to excess.
  • apply, to the dry surface, a first coat with a roller, place the NYCON F armour on the wet product and soak it to excess;
  • the next day, apply the finish coat, making sure to saturate all the pores of armour of the first coat.

On other surfaces:

  • perform a thorough cleaning in order to remove dust, dirt, grease, oil, old adhesive or paint, efflorescence, mildew and other foreign materials, while new surfaces do not require any special preparation.
  • Apply to the dry surface, the first coat of ELASTIC TOP with roller, brush, brush or spray.
  • Apply the second coat 8-12 hours after the first coat.

For the first 12-24 hours after application, protect ELASTIC TOP from rain (depending on temperature).
