CAPAROL CAPADUR TwinProof nano UV Protection

Description

Transparent, water-thinnable wood stain (wood glazing) with a high protective effect against UV light and moisture. For exterior use on dimensionally stable or limited stable wood and for dimensionally unstable wooden parts e.g. doors and windows, on limited dimensionally stable wood, e.g. wooden boards with tongue and groove, shutters, gates, etc., and suitable for coating dimensionally unstable wooden parts, e.g. panelling, balustrades, fences, etc. 


Capadur TwinProof is provided with a preservative against deterioration in the coating film due to fungal (fungi/mildew/mould) and algal attack. The film preservative has a delaying effect to infestation. On highly endangered wooden parts like soffits of flat roofs or plate-type boards (e.g. made of maritime pines) a premature infestation must be considered, depending on the biological loads on site, even before expiration of usual warranty time. 
The product cannot be used for wood with permanent contact to water and ground/soil.

Only to be used for exterior substrates, due to the content of film preservation. The interior surfaces of exterior windows and doors belong to the exterior surfaces and can be coated on all sides.

UV protection is achieved using micronised titanium dioxide.  This may lead to a whitish shade on dark wood or when applying higher quantities of product. Furthermore, discolouration may occur on wood with a high content of ingredients, e.g. oak. Hence a preliminary test application on such wood is advisable.

 

Application Method

 

Requirements for the substrate

​Stable wood, limited dimensionally stable wood and dimensionally unstable wooden parts. 

The substrate must be clean, sound/stable, dry, and free from all substances that may prevent good adhesion. 
Wood moisture content (WMC): Maximum permissible WMC of dimensionally stable wood: 13 %; limited dimensionally stable or unstable wood: 15 %.

Follow the principles of constructional wood preservation. They are the basis for longlasting wood preservation with coating materials. Follow BFS Data Sheet No. 18 section 2.2.3. for applying the product on panel-like derived timber products, e.g. solid wood, veneer layered plywood, particle boards or wood fibreboards.


Advice for the upkeep of coated wooden parts:
A long-term maintenance of value is only achievable by professional upkeep at regular intervals.​

 

Preparations

  • Existing Wood:

Sand (abrade/grind off) greyed, weathered surfaces to the stable, solid substrate and clean the surface. Impregnate with Capacryl Holzschutz-Grund.

  • New Wood:

Sand even, planed surfaces in fibre direction, clean thoroughly and remove seeping wood contents,e.g. wood resin/rosin. Impregnate with Capacryl Holzschutz-Grund.

 

Preparation of Material:

Capadur TwinProof is ready to use, but should be stirred before applying.
Brush application: Use special brushes for applying acrylic enamels (mixture of polyester and natural bristles, e.g. Orelmix).
Roller application: Use short pile polyamide roller.
Capadur TwinProof is provided with a preservative against deterioration in the coating film due to fungal and algal attack and can only be applied by spraying equipment within closed sites.

 

Surface Coaring System

1. Impregnation - Capacryl Holzchutz-Grund

2. Priming Coat - Capadur Twin Proof

3. Intermediate Coat - Capadur Twin Proof (if required) 

3. Top Coat - Capadur Twin Proof

 

Lower Temperature Limit for Application and Drying:
+ 8 °C for product, substrate and ambient air.

Drying time:

At 20 °C and 65 % relative humidity the subsequent coat can be applied  after 1 hour, at the earliest. Stacking of coated parts: after 8 hours, at the earliest. Completely dry after approx.
2 days.  The drying time is extended at lower temperatures and higher humidity or in case of insufficient air exchange, e.g. when boards are packed closely.

Tool Cleaning:

Immediately after use with water.

Application:

  • Stir well.
  • Apply by 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.
  • 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.
  • Seal opened containers well and use contents as soon as possible.

      Quality grade

      Grade A+  (the best possible grade)
       This is virtually a clear grade timber, providing a clean, consistent, almost knot-free look combined with excellent durability. 
          • Graded to BS1186-3 Part 4 Class 1; each board is practically centre pith free, one face will be sap free
          • Further hand-selection of clearest grade boards which meet stringent criteria; tight live knots with a maximum 12mm diameter and a maximum of two knots per metre on average over the total length of boards
          • As Siberian Larch is imported to the UK in board form, to avoid unsightly surface finishes such as circular-saw marks, paint / grease marks and compression marks from steel securing bands
          • Kiln-dried to moisture content of approximately 16-18% (+/- 2%)
          • End checks permitted not longer than 1.5 times width of board
          • Best available grades in Europe and guarantee that your order will not contain any commonly available, lower quality grades such B or BC
      Grade A/B
      This is one of the bests grades on the market, providing a clean, consistent, only few knot look combined with excellent durability. 
          • Graded to BS1186-3 Part 4 Class 2; each board is practically centre free, one face will be sap free, tight live knots have a maximum 35mm diameter and a maximum of two knots per metre on average over the total length of the boards
          • Kiln-dried to moisture content of approximately 16-18% (+/- 2%)
          • End checks permitted not longer than 1.5 times width of board
