Parex® MICROGOBETIS 3000

SUCTION CONTROL & BONDING COAT FOR / HIGH ABSORPTION / SMOOTH SURFACES E.G. CONCRETE AND LIGHTWEIGHT BLOCKWORK

A pink coloured liquid with a high granular consistency for ease of application recognition, and to provide excellent bonding characteristics. MICRO GOBETIS 3000 is designed to control suction to high absorption or low porosity substrates and improves the adhesion for one coat render systems e.g. MONOREX GM* & MONOREX GF*, MONOBLANCO*, BLANC DU LITTORAL* etc, and the PAREXTHERM and PAREXDIRECT Render Systems. * Refer to the specific product data sheets.

Application

Consumption

Consumption

This information is provided as guidance only, excludes wastage and will vary subject to the application and substrate.

  • 250 to 500 g/m2 (40 - 80 m2 per 20 kg bucket) depending on the substrate surface condition. 

Expect increased consumption on high absorption substrates e.g. lightweight aircrete blockwork and phenolic insulation.
Application steps

SUBSTRATE QUALITY

SUITABLE SUBSTRATES

For external and internal use on smooth, low porosity substrates such as cast concrete, concrete  panels or engineering bricks or high absorption substrates such as lightweight aircrete blockwork, common bricks and certain float-smoothed, well adhered, render surfaces.

APPLICATION

HIGH AND LOW POROSITY MASONRY AND CONCRETE SUBSTRATES

  • For low porosity substrates. Apply in a single coat using a roller or brush.
  • On high absorption substrates e.g. lightweight aircrete blockwork, apply a first coat of MICROGOBETIS 3000 and if required, this can be diluted with up to 25 % clean water to aid application of the first coat for a two coat application. Test the substrate for suction i.e. using a plasterers paddle brush, cast some water at the treated surface and if it sucks in, apply a further coat, if it sits on the  surface, the substrate is ready for the render application. To avoid excessive applications, it is recommended this procedure is completed after the first coat, as subsequent coats may not be required. Once suction control is satisfactory continue with the application

EXTERNAL WALL INSULATION SYSTEM USING PHENOLIC INSULATION

  • When applying MICRO GOBETIS 3000 onto phenolic insulation follow the same procedure as detailed above for high absorption substrates. This application will require a minimum of two coats.

GENERAL APPLICATION NOTES

  • The render coat can be applied as soon as the MICRO GOBETIS 3000 is dry, i.e. after 1 to 24 hours depending on weather conditions. On Phenolic insulation this can generally occur  immediately after the 2nd coat.
  • Fully mix the product before use to maintain an even consistency.
  • MICRO GOBETIS 3000 is best applied by brush or medium lambs wool roller as other roller types
