The optimal processing and drying temperature is between 15 and 30 degrees Celsius (applies to the substrate, the product and the ambient temperature). Drying temperature should be at least 5 degrees Celsius.
Important: Never paint in blazing sun. Always ensure good air circulation.
Drying can be significantly delayed in adverse weather conditions (high humidity, low temperatures, low air exchange) and also due to the type of wood.
When used outdoors, it is important to protect freshly painted wood from rain until completely dry.
We recommend a glazing coat. Koralan® natural oils are particularly suitable. The product family includes Koralan® Color-Lasur (Colour Scumble), Koralan® Designlasur (Design Scumble), Koralan® Holzöl (Wood Oil), Koralan® Holzöl Spezial (Wood Oil Special) and Koralan® Vergrauungslasur (Greying Scumble).
The lightest shade is “UV Natural”, which highlights the wood's own color and yet offers very good UV protection. A colourless coat of paint outdoors does not provide UV protection and is therefore not sufficient as a single coat of paint.
If you want to protect the paint from blue stain and mould infestations, we recommend Koralan® Imprägnier Grund (Impregnation Primer). This KORA® product is also used as a bonding agent for subsequent layer-forming coatings such as Koralan® Außenfarbe (Exterior Paint) or Koralan® Dekorlasur (Decorative Scumble). Primers such as Koranol® Grund Farblos (Primer Colourless) or Koranol® Holzbau Grund (Wood Construction Primer) also provide protection against rot and wood-destroying insects.
Many KORA® wood protection products meet the requirements of DIN EN 71-3 “Toy Safety” in accordance with Directive 2009/48/EC and can be easily used for children's play equipment.
Our recommendation is an opaque coat of paint. Pre-treatment: For new or untreated wood outdoors, we recommend using a water-based wood protection primer (e.g. Koralan® Imprägnier Grund - Impregnation Primer). New planed wood surfaces should be sanded to improve adhesion and material absorption (80/120 grit). Intermediate coat: In the case of light shades or even white, Koralan® insulating paint white should be used to prevent penetrating colorant wood ingredients.
Please note: By washing out wood ingredients, adjacent components may become dirty. Top coat: Two coats of Koralan® Außenfarbe (Exterior Paint). Use material undiluted. When using old wood, please note the following: First remove non-adhesive old paints completely. Remove dirt and dust from old intact and stuck paints, sand them if necessary. Then two coats of Koralan® Außenfarbe (Exterior Paint). Koralan® Außenfarbe (Exterior Paint) and Koralan® Isolierfarbe (Insulating Paint White) meet the requirements of DIN EN 71-3 “Safety of toys” in accordance with RL2009/48/EC. Please follow the instructions on the technical data sheets and on the containers.
It is best to store the products in original containers. The containers must be sealed tightly after use. The storage temperature should be between 5 and 30 degrees Celsius. Please follow the instructions on the containers.
Preparing the wood surface is very important for the durability of the subsequent coat of paint.
A rough sawn surface (fine bandsaw cut) is optimal. Micro-riffling is also very suitable. Planed surfaces offer the worst conditions for good durability and bonding of coating and substrate. Planed surfaces should therefore always be sanded to remove high wood fibers and to achieve a uniform wood surface. The same applies to weathered wood and wood with an uneven surface structure.
In the event of an infestation (e.g. in the roof truss), you should consult an expert. You can find experts in your area by searching directly on the DHBV (German Wood and Building Protection Association e.V.) website at www.dhbv.de. Or talk to our team in Advice & sales. Please contact us so that we can arrange a contact for you. You can treat localized infestations (e.g. on a piece of furniture) with products such as Koranol® Ib.
All products are ready to use and should not be diluted. In principle, it is possible to mix different shades of a product. However, we do not recommend this. Anyone who does this anyway should note down the mixing ratio for later traceability.
The safest way to Desired color runs via our Koralan Tint system. It produces almost any color for seven KORA® products.
Wooden windows and doors are among the dimensionally stable components that are exposed to the weather. We recommend, for coating, our middle layer scumble Koranol® Compact MSL. It is important to always repair paint damage as quickly as possible in order to maintain weather protection and the appearance of the paint in the long term.
Koralan® Holzöl (Wood Oil) and Koralan® Holzöl Spezial (Wood Oil Special) are natural oil and water-based care oils for outdoor wood. Both protect wood surfaces very well against greying and the effects of weather (sun, rain).
Koralan® Holzöl (Wood Oil) is perfect for initial coating and maintenance of wooden elements (e.g. garden furniture or decking boards) made of hardwoods such as Bangkirai or Garapa. The product meets the requirements of DIN EN 71-3 “Safety of Toys” in accordance with Directive 2009/48/EC.
Koralan® Holzöl Spezial (Wood Oil Special) is a wood-protective impregnation, primer and decorative weather protection in one product. It is an approved biocidal product in accordance with Regulation (EU) 528/2012 and is preventatively effective against blueness (in accordance with EN 152) and mold (in accordance with EN 15457).
Scope of application: initial coating and aftercare of softwood elements, e.g. terraces, wooden facades, garden furniture, privacy screens. Please note the notes on the Technical data sheets and on the containers.
It is not possible to make a general statement about shelf life and aftercare intervals due to the various influencing factors.
Basically, the lighter the shade, the shorter the gaps are. The durability of a coating depends on various factors: location/exposure, UV radiation, intensity of weathering, structural wood protection (e.g. roof overhangs), color, wood surface (rough sawn, planed, sanded), wood selection.
As a rough guideline, one to three years can be assumed for lighter shades and two to four years for darker shades.
Only regular maintenance protects your wood surface from sun, rain and greying and reduces the swelling and shrinkage of the wood.
