Features & Benefits

• Suitable substrates:
  • External and internal use
  • Smooth, low porosity substrates such as cast concrete, concrete panels or engineering bricks
  • High absorption substrates such as lightweight aircrete blockwork, common bricks and certain float-smoothed, well adhered, render surfaces
• Pink coloured liquid with a high granular consistency for ease of application recognition
• Excellent bonding characteristics
• Designed to control suction to high absorption or low porosity substrates
• 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

High/Low Porosity Masonry & 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 MICRO GOBETIS 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 Sustem 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 sometimes bunch the product
• Coverage 250 to 500 g/m2 depending on the substrate surface condition. Expect increased consumption on high absorption substrates e.g. lightweight aircrete blockwork and phenolic insulation

Limitations

• Do not dilute the product unless using as recommended on the above applications
• The substrate must be dry, sound, clean and free from de-bonding agents and powdery substances
• Do not apply on wet substrates
• Temperature range : +5°C to + 30ºC
