Water-based white primer concentrate with film preserver
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
- Soft and hard woods
- Dimensionally stable wood building elements: e.g. windows and doors
- 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
- Economical: concentrate is made suitable for dipping or flow coating with water
- Less discolouration due to water-soluble substances in the wood
- Good flow characteristics on untreated and impregnated wood
- Good pore wetting performance
- Outstanding (wet) adhesion
- Film preserver protects against microbial damage
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%
If necessary, impregnate non-resistant woods with a wood preservative* (*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".
Temperature of material, environment and substrate: min. +15 °C to max +30 °C.
Stir well, including during application or after a break in work.
Qualified specialist companies: brushing, dipping, flow-coating and spraying in closed systems only.
For application by immersion & flooding, adjust viscosity with water to 35 - 40 s in ISO cup 3 mm.
Once dry, apply an intermediate coat of this or another suitable product.
Seal opened containers well and use contents as soon as possible.
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 coating to a trial surface and conduct a suitability test on the desired area of use.
Prior to full application, please apply a test coat to a sample area under practical conditions using the desired system, then test or examine the surface properties.
Ensure good ventilation.
The best flow results on Accoya, oak and chestnut are achieved at a pH value of 9.0–9.5, corresponding to an additive content of 0.3–0.5% VP 20829 Additive (0366).
If the viscosity increases due to evaporation, water must be added (target viscosity: runout time approx. 35 - 40 s in a 3 mm ISO cup).
If foaming occurs in the flow coating system, it is recommended to add 0.2-1.0% VP 9325 defoaming agent - strength 2.
The product's sealing effect may be impaired if it is diluted too thinly, if the wood is too wet or if the recommended coating sequence, application volumes and drying times are not observed.
With water based coating systems, there is always a residual risk that substances contained in the wood will cause discoloration.
The system finder on our website www.remmers.com contains coating recommendations for specific wood types to be used when treating windows and exterior doors.
Ready for overcoating: after approx. 4 hours
(at 23 °C and 50 % RH)
Ready for overcoating if forced drying is used: after approx. 90 minutes
(20 minutes draining / 50 minutes drying phase (35 - 40 °C)/20 minutes cooling phase)
Low temperatures, poor ventilation and high humidity delay drying.
Dilute with water if necessary
Working tools / cleaning
Acrylic brush, dipping tank, flow coating system, spraying tunnel
Clean tools with water or Aqua RK-898 Cleaning Concentrate immediately after use.
Storage / shelf life
If stored unopened in its original container in a cool, dry place and protected against frost, the product will keep for at least 12 months.
80 - 120 ml/m² per application
Observe the information sheets “Upkeep and Maintenance of Dipping Tanks and Flow Coating Facilities” and “Information on Workplace Hygiene”.
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.
Safety / regulations
For further information on the safety aspects of transporting, storing and handling the product and on disposal and environmental matters, please see the current Safety Data Sheet.
Do not use on wood intended to come into direct contact with food or feed.
