Field of Application

Paint with essential benefit: Organically cross-linked nano-quartz particles form a compact, mineral-hard, three-dimensional quartz matrix structure against soiling and keep facades clean for a longer period.

The special silicone resin/binder combination effectuates water-repellent, highly water vapour permeable facade paint coatings, thus fast-drying after rainfall and when moist with dew. Applicable on mineral and synthetic (organic) renders, coated or uncoated. ThermoSan NQG is suitable for all types of current, stable ETICS/EWI system surface coatings, e.g. synthetic (organic) renders, silicone renders, lime renders and lime-cement renders.

Material Properties

  • Provided with an encapsulated preservative against deterioration in the coating film due to algal and fungal attack.
  • Alkali-resistant, hence unsaponifiable.
  • Highly CO2 permeable.
  • Non-film-forming, micro-porous.
  • ThermoSan NQG is able to wash fine shrinkage cracks in render surfaces.
  • Contains special pigments, showing a photocatalytic effect.
  • Reduces visible marks on dark colours, if surfaces are subjected to mechanical loads.

Material Base / Vehicle

Combined silicone resin emulsion and innovative type of hybrid binder, on an inorganic/organic basis.

Packaging/Package Size

  • Standard Product: 12.5 litres
  • ColorExpress: 1.25 litres, 7.5 litres and 12.5 litres

Colours

White.
ThermoSan NQG can be tinted with AmphiSilan colourants. If more than one bucket is manually tinted, all product must be thoroughly mixed before use in order to avoid colour differences.

Quantities of 100 litres or more in individual colours may be ordered ready-tinted ex factory. ThermoSan NQG is tintable via the ColorExpress tinting & mixing machine system in limited colour shades of all current colour collections. Check tinted product before applying to avoid colour differences. Always use tinted paint of same batch, when applying on seamless surfaces.

Brilliant, intensive colours may have a lower opacity (hiding/covering power). It is therefore advisable to apply a first coat in a similar hiding pastel tint, based on white. A second finishing coat may be necessary.

Suitable Substrates

The substrate must be sound/stable, dry, clean, and free from all substances that may prevent good adhesion. In Germany: Follow VOB, part C, DIN 18363, section 3.

Substrate Preparation

Clean surfaces with algal or fungal attack (fungi/mildew/mould growth) by water jet, in compliance with the regulations. Then use Capatox or FungiGrund and allow to dry.

New and Existing, Sound ETICS/EWI Systems with Surfaces of Synthetic Resin-Bound (Organic) Render, Silicone Render, Lime Plaster (PIc) and Lime-Cement Plaster (PII) / Minimum Compressive Strength according to DIN EN 998-1: 1 N/mm2:
Clean existing renders by suitable wet cleaning method. Maximum temperature for high-pressure water jet: 60 °C. Pressure: max. 60 bar. Allow to dry thoroughly. Coat with ThermoSan NQG according to the type of existing finish render and details as mentioned below.

Renders in Mortar Groups/Classes PIc (Lime Plaster), PII (Lime-Cement Mortars), PIII (Cement Mortars) / Minimum Compressive Strength according to DIN EN 998-1: 1 N/mm2:
New renders must be left untreated for a sufficiently long holding time, normally for 2 weeks at 20 °C and 65 % relative humidity. Adverse weather conditions, e.g. influenced by wind or rain, extend the curing process and correspondingly longer holding times must be respected.  Coat with ThermoSan, adding 10 % of AmphiSilan-Tiefgrund.
The risk of calcareous efflorescence on alkaline finish renders of mortar classes PIc, PII and PIII can be minimised by an additional priming coat of CapaGrund Universal and the finishing render may be coated after a holding time of 7 days.

Existing Renders/Plasters:
Repairs must have adequate time to cure and dry. Substrates with normal absorbency can be coated with ThermoSan NQG, adding up to max. 10 % of AmphiSilan-Tiefgrund. Prime highly porous, absorbent, slightly sanding renders with AmphiSilan-Tiefgrund.
Prime highly sanding, chalking renders with AmphiSilan-Putzfestiger.

New Coatings of Silicate Finish Render:
Prime with Sylitol® NQG-W (facade paint).

Existing Coatings of Silicate Paint and Render:
Clean adherent, stable coatings mechanically or with high-pressure water jet, in compliance with the regulations. Remove unstable, weathered coatings by abrading, sanding/grinding or by scraping off. Apply one priming coat of AmphiSilan-Putzfestiger.

Fibre Cement Boards (with or without Asbestos Fibres):
Germany: Follow BFS-Merkblatt (Data Sheet) No. 14 or TRGS 519 for coatings on asbestos cement boards.
Prime in accordance with Technical Information No. 650. Prime free-standing boards on both sides as well as on all edges. Prime new, highly alkaline fibre-cement boards with Disbon 481 EP-Uniprimer to avoid calcareous efflorescence and thin ThermoSan NQG with 10 % of AmphiSilan-Tiefgrund for intermediate coat.

Cement-Bound Wood Chipboards (Particle Boards):
Apply one priming coat of Disbon 481 EP-Uniprimer on highly alkaline boards to prevent calcareous efflorescence. Thin ThermoSan NQG with 10 % of AmphiSilan-Tiefgrund for intermediate coat.

Sound/Stable Coatings of Synthetic (Organic) or Silicone Render:
Clean existing coatings by suitable means. Allow wet cleaned surfaces to dry thoroughly before further treatment.

Sound/Stable Emulsion Paint Coatings:
Clean soiled, chalking coatings by high-pressure water jet, in compliance with the regulations. Apply one priming coat of ThermoSan NQG, mixed with 10 % of AmphiSilan-Tiefgrund. If other cleaning methods are used (washing, wire brushing, hosing with water), prime with AmphiSilan-Putzfestiger.

Unstable Coatings of Emulsion Paint or Synthetic (Organic) Render:
Remove completely by suitable means, e.g. mechanically or via paint stripper, followed by surface cleaning with a high-pressure water jet, in compliance with the regulations. Apply one priming coat of ThermoSan NQG, mixed with 10 % of AmphiSilan-Tiefgrund. Prime chalking, sanding, absorbent surfaces with AmphiSilan-Putzfestiger.

Unstable Mineral Paint Coatings:
Remove the coating completely to the stable substrate by sanding off, brushing off, scraping off or using high-pressure water jet, in compliance with the regulations, or by other suitable means. Allow wet cleaned surfaces to dry well before further treatment. Apply one priming coat of AmphiSilan-Putzfestiger.

Fair Faced Brickwork:
Only fair faced bricks or clinker bricks of frost resistant quality and free of foreign inclusions that leave marks are suitable for paint coatings. Masonry must be dry and free of salts/salty efflorescence, jointing must be free of cracks. Apply one priming coat of AmphiSilan-Putzfestiger. If brownish discolouration occurs in the intermediate coat, recoat with solvent-based facade paint Duparol.

Sand-Lime Brick Masonry:
Only frost resistant fair faced bricks, free of foreign inclusions that leave marks, e.g. sand or loam, are suitable for paint coatings. Jointing must be free of cracks. Clean chalking surfaces. Remove salty efflorescence by dry wire brushing. Germany: Follow BFS-Merkblatt (Data Sheet) No. 2. Apply one priming coat of AmphiSilan-Tiefgrund.

Surfaces with Salty Efflorescence:
Remove salty efflorescence thoroughly by dry wire brushing and prime with Dupa-grund. Coating of such surfaces must be considered a risk for which we cannot accept responsibility, since even after the most thorough treatment the efflorescence may recur.

Defects:
Repair small defects with fine filler Caparol Fassaden-Feinspachtel, deeper damages up to 20 mm preferably with Histolith-Renovierspachtel and prime repaired areas subsequently. Follow Technical Information.

Method of Application

Apply with paint brush or roller.
For airless application we recommend the use of ThermoSan NQG Nespri-TEC using the Nespri-TEC spraying method.

Surface Coating System

Priming or Intermediate Coat
ThermoSan NQG, diluted to a max. of 10 % with tap (potable) water.
For maintenance coat: In most cases an additional priming coat can be omitted, if max. 10 % of AmphiSilan-Tiefgrund is added.

Finishing Coat (Topcoat):

ThermoSan NQG, diluted to a max. of 5 % with tap water. Minimum drying time between coats:
12 hours.

Consumption

Approx. 150 - 200 ml/m2 per coat on smooth substrates. On roughly textured surfaces correspondingly more. Determine the exact amount of material required by coating a test area on site.

To get the best protection against algae and fungal attack, it is necessary to apply two coats with a minimum of 400ml / m2, for performing at least a layer thickness in the middle of 200 microns. Each additional application with a consumption of min. 200 ml / m2 per coat increases the layer thickness by approximately 100 microns. On rough surfaces and consumption are correspondingly higher.

Application Conditions

Low Temperature Limit for Application and Drying:
+5 °C for product, substrate and ambient air.

Drying/Drying Time

At +20 °C and 65 % relative humidity surface-dry after 2 - 3 hours and recoatable after 12 hours. Completely cured and ready for stress after approx. 3 days. Lower temperatures and higher humidity extend the drying time.

Tool Cleaning

Clean tools/equipment immediately after use with soapy water.

Note

Germany: Follow BFS Data Sheet No. 21 for use on ETICS/EWI systems. Do not apply on sun heated substrates, during strong wind, fog or rain, high relative humidity or imminent rain and frost. 
To avoid lapping, the paint should be applied wet-on-wet and without interruption. Do not apply on horizontal surfaces exposed to rain or moisture. Only intact ETICS/EWI systems can be renovated by paint coatings. For unsound surfaces we refer to the Capatect Renovation System for ETICS/EWI systems. Do not use solvent-based primers on ETICS with polystyrene insulation (EPS); exception: AmphiSilan-Putzfestiger. Luminosity/lightness index (LI) must be > 20 for tinted paint coatings.

ThermoSan NQG contains special algicidal and fungicidal agents to counteract the forming of organic growth (algae & fungi/mildew/mould) on the coating film. The depot of agents offers a prolonged protection, but the algicidal & fungicidal effect is limited by the special facade conditions, e.g. intensity of organic attack/infestation and moisture. Therefore a durable protection cannot be guaranteed. 
Mechanical loads on matt facade paints in dark colour shades may produce bright-toned stripes as a product specific property (no writing resistance), but the effect is minimised when using ThermoSan NQG.In case of moist weather conditions (rain, dew, fog) yellowish transparent traces of additives, showing a slightly glossy shine and stickiness, may occur on the surface of compact, cool substrates or by means of delayed drying caused by the weather. The traces of additives are water-soluble and will disappear under the influence of a sufficient water quantity, e.g. repeated intensive rainfalls. The quality of the dried coating will not be affected by these changes. In case of direct reworking, all traces of additives must be pre-wetted and completely removed after a short reaction time. An additional priming coat of CapaGrund Universal must be applied. The traces cannot occur when the material is applied under suitable climatic conditions.

Copper ions in draining rain water (run-off water) may react with ingredients of ThermoSan NQG and may cause a brownish discolouration. Thus all relevant copper surfaces must be protected against oxidation. Alternatively our product Muresko SilaCryl® can be used.

Touching up surfaces is depending on many parameters and may be visible after drying.
