Product specifications
On delivery
The stated values represent typical product characteristics and are not to be construed as binding product specifications.
Field of application
- For use on exterior wood
- Dimensionally stable wood building elements: e.g. windows and doors (including their interior surfaces)
- Wood building elements with limited dimensional stability, e.g. folding shutters, matchboarding, summerhouses
- Wood building elements with no dimensional stability: e.g. fences, framework, carports, planking
- Clear UV+ can also be used as a sacrificial layer over pigmented variants to prevent the wood from darkening
- For use by professionals

-
Preparation
-
Substrate requirements
The substrate must be clean, dry, free of dust, grease and loose substances, and prepared in the correct manner.
Dimensionally stable wood building elements: wood moisture content 11-15%
Wood building elements with limited or no dimensional stability: wood moisture content max. 18%
-
Preparations
Thoroughly remove any dirt, grease and non-adhering old coatings.
Sand grey and weathered wood surfaces down to sound, bright wood.
Remove any loose and torn knots as well as resin that bleeds from the wood and clean with a suitable product (e.g. V 101 Thinner).
Thoroughly sand any old coatings that are still intact.
If necessary, the substrate can be made more uniform with Aqua RG-27.
Exterior wood that is to be protected against rot and blue stain and/or wood-destroying insects should be pre-treated with a suitable wood preservative* [see system products]. (*Use biocides safely. Always read the label and product information before use.)
Observe BFS Code of Practice No. 18 "Coatings on Wood and Wooden Working Materials in Outdoor Areas".

Application
-
Stir well and apply quickly using a brush.
Apply in the direction of the grain.
Carry out light intermediate sanding on particularly elegant surfaces prior to applying a finishing coat.
Apply a second coat once the first has dried.
If required, Clear UV+ can be used as a third coat to permanently fix the desired colour (sacrificial layer that is renewed when renovating).
The procedure can also be used on surfaces that have been pre-treated with HSL-30/m* or Wood Cream*.
This procedure is not advisable on substrates that have been treated with white products (darkening, yellow tint from Clear UV+).
End grain areas should be painted over with several coats of the material in the corresponding colour to protect against water absorption.
Windows and exterior doors require 3 coats.
All colours can be mixed with one another.
Seal opened containers well and use contents as soon as possible.

Application instructions
-
Check colour, adhesion and compatibility with the substrate by setting up a trial area.
Before coating technically modified woods and wood-based materials, apply the product to a trial surface and conduct a suitability test on the desired area of use.
Cut end-grain surfaces at the bottom to create a water-drip edge.
Due to the different covering properties of white and pastel varnish colours, the optical appearance may vary depending on the substrate. It must be checked in advance whether discolouration of the varnish may occur due to substances contained in the wood.
In order to take account of and clarify these issues, a trial surface must be prepared in order to ensure that the surface meets expectations.
Each layer of stain results in a more intense colour and a glossier finish.
Make sure that the area is well ventilated during processing and drying.
Areas that are being coated or dried should be protected against rain, wind, sunlight and condensation.
Compatible with plastics and bituminous materials once dry.
Mechanical damage, especially to clear coatings, must be immediately repaired with "clear UV+" to prevent discolouring, caused e.g. by blue stain.
Shorter maintenance intervals should be planned for the shades "white" and "clear UV+".
Risk of self-ignition (DGUV information brochure 209-046).
The product should not be applied at the same work stand as NC-based varnishes or stains. Collect any textiles soiled with the product (e.g. cleaning rags, work clothing) in fire-resistant waste containers and dispose of properly.
-
Drying
Low temperatures, poor ventilation and high humidity delay drying.
-
Working tools / cleaning
-
Paintbrush with natural bristles, flat brush
-
Clean tools immediately after use with V 101 Thinner.
Dispose of the remains from cleaning properly.
-
Storage / shelf life
-
At least 36 months in unopened, original containers stored cool, dry and protected from frost.
Use the contents of open containers as quickly as possible.
-
Usage
-
1st coat: 100 ml/m²
2nd coat: 60 ml/m²
Clear UV+: 3 coats
-
General information
-
On planed larch and softwoods with a high resin content, the coating may have reduced adhesion and resistance to weathering. This is especially the case on horizontal year rings, knots and areas of winter growth that are high in resin. Maintenance and renovation must be carried out more frequently on these surfaces.
The only remedy for this is pre-weathering or very coarse sanding (P80).
If these wood types are rough-sawn, considerably longer maintenance and renovation intervals are to be expected.Observe the regulations concerning design principles for wood protection.
Do not use on horizontal surfaces without drainage slopes and without edge radius, avoid accumulated moisture.

Disposal instructions
-
Larger quantities of leftover product should be disposed of in the original containers in accordance with the applicable regulations. Completely empty, clean containers should be recycled. Do not dispose of together with household waste. Do not allow to enter the sewage system. Do not empty into drains.
