Intergrain DWD

Exterior Transparent Door, Window and Decking Finish

Intergrain DWD was developed to provide a tough, transparent weather resistant, semi gloss finish for door, window and decking timbers under harsh Australian conditions. It is formulated on an advanced water-based UV curing acrylic polymer which resists ultra violet radiation, cracking, peeling and fungal attack, whilst retaining long term flexibility.
Released in 1985 and subject to an ongoing product development programme DWD has earned a reputation for performance and durability under Australian conditions.

APPLICATION DATA
Method of Application:
Timber Pre-Treatment: 		Quality brush, Lambswool applicator, airless or high volume, low pressure spray. All new or bare timber must be pre-treated with Dimension 4 prior to applying DWD IMPORTANT DO NOT APPLY BY ROLLER
Number of coats:2 generous coats. Important when first applied correctly DWD will have an opaque biscuit colour becoming transparent on drying. Do not brush out until clear on application.
Coverage:Roughsawn Timber: approx. 6 - 8 sq. mt. per Lt.
Sawn Timber 8 - 12sq. mt. per Lt.
Dressed Timber approx. 12sq. mt. per Lt. It is important this coverage is adhered to, in order to achieve adequate film build and design performance.
Cleanup: Water.
Thinning: Water, up to 10% for spray application only. Additional coats may be required to achieve adequate film build if thinned.
Drying:Touch dry 1 hour at 20deg.C. Lower temperatures and high humidity will retard drying. Full UV curing in 30 days.
Recoating: Same as for UVC.
Application Temperature: Do not apply above 30 degrees Celcius or below 10 degrees C, or in direct sunlight, or onto hot surfaces.

WHERE TO USE

On new or correctly prepared door, window, decking ,and garden furniture timbers, including Western Red Cedar, Meranti, Cypress Pine, Jarrah, Treated Radiata Pine, Brush Box, Tallowood, Merbau, etc.

NOTE:

Oily resinous timbers such as Cypress Pine, Merbau, Brush Box, Tallowood etc. should be allowed to weather for 4 - 6 weeks, followed by cleaning with Intergrain Reviva Timber Cleaner. Where weathering is not possible the timber should be pre-cleaned with Intergrain Reviva Timber Cleaner before painting.

NOTE:

DWD is not recommended for Reeded or Grooved Timber Decks. For exterior weatherboards, siding, pergolas, fascias, etc. we recommend Intergrain UVC

SURFACE PREPARATION:

All timber to be coated with DWD must be pre-treated with Intergrain Dimension 4 Timber Pre-Treatment and all non-resinous, non-oily timbers should be pre-treated or coated as soon as possible before, during or after installation to avoid sun and moisture damage and fungal attack. Timber to be coated must be clean, dry and free from dust, dirt, mildew, and linseed oil. Previous finishes must be removed and the timber sanded and cleaned prior to application. Timber that is weathered grey, stained, discoloured or effected by mould and mildew should be cleaned with Intergrain Reviva Timber Cleaner. After cleaning, mildew, mould and algae affected timber should be treated with Intergrain TSS Timber Sterilising Solution * used according to instructions to kill mould spores.

* This is a biocidal wash which can also be used for cleaning tiles in kitchens and bathrooms or used as a general household cleaner.

IMPORTANT NOTE:

The rounding of sharp timber edges with sandpaper before painting is highly recommended to improve film integrity. In coastal areas wash down timber with clean water to remove salt deposits and allow to dry before painting.

WARNING:

Steelwool must not be used to prepare surfaces to be coated with DWD.

APPLICATION:

Stir thoroughly before and during use. Do not thin. Apply 2 generous coats by brush, airless or high volume low pressure spray. Avoid over brushing and lay off in direction of grain. IMPORTANT: When first applied correctly DWD should appear as an opaque biscuit colour. DO NOT BRUSH OUT UNTIL CLEAR. Product will become transparent on drying. Allow minimum 4 hours, drying between coats. Do not apply in strong sunlight or to hot surfaces or surfaces that will be subjected to strong sunlight within 4 hours of application. Application under these circumstances will lead to temperature/vapour blisters and poor adhesion. Do not sand between coats. Do not apply below 10deg.C. or above 30 deg.C. Do not apply if rain or dew is expected within four hours of application. Lightly dampening timber before painting in temperatures above 25deg.C. will ease application. Do not apply if rain or dew is expected within four hours of application. Exposed end grain should be sealed with several heavy coats to prevent moisture absorption.

MAINTENANCE:

See Notes on UVC Page. Weathered DWD can be removed with Intergrain Liquid 8 Paint Remover and power washing where possible.

CAUTION:

Keep out of reach of children: Ensure adequate ventilation during use. Avoid contact with skin and eyes.

PACKAGING:

1, 4 and 10 Litre cans.
