Article No. 272303
Pigmented, transluctent, decorative wood preservative stain for exterior wood protection and finishing
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
- Wood without ground contact
- Wood building elements with no dimensional stability: e.g. fences, framework, carports, planking
- Wood building elements with limited dimensional stability, e.g. folding shutters, matchboarding, summerhouses
- Primer, intermediate and finishing coats
Properties
- Low-build stain in brilliant colours
- Only one coat needed
- 3 in 1: impregnation, priming and stain
- Impregnation effect: saturates wood to protect against moisture
- Diffusion-open protective film: moisture can escape
- Water-repellent: wet surfaces dry quickly
- Protection against weathering (constructive protection and the protection provided by the product) reduces the risk of blue stain and rot
- Film protects coating against blue stain, mould and algae
- Cream form: no need to stir, non-drip for overhead working
- Self-levelling
- Does not flake
- Subsequent treatment without sanding
-
Preparation
-
Substrate requirements
Wood building elements with limited or no dimensional stability: wood moisture content max. 18%
-
Preparations
Completely remove old coatings (e.g. paints or medium-build stains), bark, bast and dirt.
Remove loose and torn knots as well as resin that bleeds and clean with a suitable product (e.g. Remmers thinner & brush cleaner).
Smooth, planed wood surfaces should be sanded and dusted before the coating is applied to ensure better absorption.
Take appropriate measures to protect adjacent building elements and materials that should not come into contact with the product.
Observe BFS Code of Practice No. 18 "Coatings on Wood and Wooden Working Materials in Outdoor Areas".

Application
-
Apply using a brush or roller.
Apply in the direction of the grain.
After approx. 30 minutes, check the surface for excess material and smooth it off if necessary.
After drying, apply a second coat if required.
When coating continuous surfaces, only use materials with the same batch number as slight differences in colour, gloss and texture may occur.
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.
If the surface is overcoated with other products it is recommended to test the adhesion to the substrate.
Use the clear variant on sheltered exterior surfaces only, such as roof undersides, or as a primer.
Rainfall may cause water soluble substances to bleed from wood that is rich in such substances, e.g. oak, red cedar, afzelia, redwood, etc. This may lead to the discolouration of light-coloured masonry or render.
Pre-testing is recommended also on other woods.
Cut end-grain surfaces at the bottom to create a water-drip edge.
Apply two subsequent coats of end-grain wood preservative to end-grain wood and cut surfaces in order to protect them against moisture.
Each layer of stain results in a more intense colour and a glossier finish.
-
Drying
Approx. 12 hours at 20 °C and 65% relative humidity.
Low temperatures, poor ventilation and high humidity delay drying.
Drying time may be significantly delayed depending on the type of wood, e.g. larch.

Thinning
Ready to use
-
Working tools / cleaning
-
Brush with natural bristles, flat brush, velour roller
-
Clean tools immediately after use with thinner and brush cleaner.
Ensure that any residue from cleaning is disposed of correctly.
-
Storage / shelf life
-
At least 36 months in unopened, original containers stored cool, dry and protected from frost.
-
Usage
-
Approx. 200 ml/m² in 1-2 coats
-
Planed or very thick woods are less absorbent and require a second coat
-
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.
