Baumit NanoporTop finish render is a self-cleaning and pollution-resistant, ready-to-use silicate, textured top coat render. The render contains photocatalystic technology for external use

Baumit NanoporTop is easy to use, breathable, decorative and pollution resisting. Use as a finish over Baumit base coat and bonding coat renders. Perfect as a finish in areas where high weather and stain resistance is required.

Use for protection and enhancement of façades and façade surfaces over old and new mineral renders and fillers and on concrete. For preserving historical monuments, renovations and as a topcoat with external wall insulation systems.

Baumit NanoporTop is low stress drying, highly weather resistant, water vapour and CO2 permeable, stain resistant, non-flammable and easy to use.

The microstructural surface, nano-crystalline and inorganic additives significantly reduce staining compared to other coatings.

Baumit NanoporTop can be used as a finish coat render on all main wall areas.

It can be applied on to old and new mineral renders (lime and cement renders), organic base coat renders in the Baumit range and on to EWI systems.

Substrate:

Substrates must be sound, clean, dry, free from frost, dust efflorescence and not water repellent. Existing mineral based coatings and paints must be sound and well bonded to the substrate (confirm with pull off tests and/or cross cut tests acc. To Baumit guidelines).

Suitable substrates:

  • Mineral basecoats on External Wall Insulation systems,
  • Lime and cement renders, concrete.
  • Well bonded mineral, silicate paints and coatings.
  • Gypsum plasterboards (pre-treated with 2 coats of Baumit SperrGrund).

Refer to Baumit for advice regarding other substrates and substrate preparation.

Surfaces must always be prepared with a full and even coat of Baumit UniPrimer before applying Baumit NanoporTop. Allow to dry for 24 hours. Refer to Product Data Sheet.

Mixing:

Baumit NanoporTop must be well and slowly mixed with an electric hand mixer before application. It may not be mixed with other paint materials. Where required a minimal amount of water (max. 1%) may be added to improve workability.

Application:

The Baumit NanoporTop is applied with a stainless steel trowel or a fine spray machine and trowelled through to the grain thickness to produce a full and even coat. The surface is then textured using a plastic float, moving in tight circular motions.

It should be applied systematically and continuously in complete sections.

The final thickness of the Baumit NanoporTop is dependent on the grain size but as a general rule it will be around 0.5mm thicker than the grain size. For example the 1.5mm will be around 2mm thick and so on. Please refer to the data sheet.

Typically the 1.5mm will use up to 2.75kg/m2, the 2mm will use up to 3.5kg/m2 and the 3mm will use up to 4.6kg/m2.

The air, material and background temperature must be above +8° C during application and curing. Protect the facade from direct sunlight, rain and strong winds (i.e. with scaffold nets). High air humidity and low temperatures can prolong drying times considerably.

Products from different batches must be mixed together prior to application. Colour tone development can be affected by the background conditions, temperature and air humidity level.

Baumit NanoporTop is equipped with a basic level of protection against algae and fungal growth. This achieves a preventative and inhibiting effect. For projects in critical environments (e.g. areas with above average humidity, rainfall, close proximity to water, plants, shrubbery, trees and woodland) we recommend an increased level of protection. A long term eradication of algae and fungal growth cannot be guaranteed.

The sands used in the Baumit facade renders are natural products. On occasion some of the sand grains may appear slightly darker. This does not in any way constitute a problem with quality of the product, but may represent a faint optical detraction, due to the natural properties of the raw materials.

A Light Reflectance Value lower than 25 must not be used for application on to External Wall Insulation systems.

Baumit NanoporTop should be left to dry for at least 14 days ( at +20 C° and 60 % rel. humidity) before receiving any further coatings.

Protective measures:

  • Protect eyes and skin, and surrounding areas, especially glass, ceramic, brick, natural stone, varnishes and metals. Wash away any splashes with plenty of water.
  • Do not allow to dry and harden.
  • Clean tools and equipment thoroughly with water immediately after use.

Baumit NanoporTop should only be used when temperatures are above 8 degrees Celsius and away from strong, drying winds and direct sunlight. Because the material has to dry out to harden and cure, if the atmospheric humidity is very high and temperature is low drying times will longer.
