J3809/J9809/J7809

Features & Uses

Awlwood MA is an exterior clear system made up of a Primer and Clear Gloss Finish. The synergistic effect of combining the Primer and Clear together results in an outstanding performing system that adheres and bonds directly to the wood cellular structure giving extended performance and retaining the same gloss, DOI and natural appearance as first application. Awlwood MA Primer incorporates Flex-Link™ technology, which works by adhering and embedding into the wood to provide a strong yet flexible link with the wood structure and the coating whilst allowing the natural coating and grain to shine through. This gives superior flexibility and unrivalled resistance to delamination at damage points.

For exterior, above waterline use only.

Specification Data

Type: Low VOC Acrylic Urethane

Color: Clear (J3809), Yellow (J9809), Red (J7809) Packaging: Available in Quarts.

Theoretical Coverage: 10m²/lt or 407.4 ft²/gl

Coverage calculations are based on theoretical transfer efficiency of 100%. Actual coverage rate obtained will vary according to equipment choice, application techniques, part size, and application environment. Recommended Wet Film Thickness: ~4.0 mils (100 microns) per coat by brush and by roller application.

Recommended Dry Film Thickness: 2.0 mils (50 microns) per coat by brush and by roller application.

NOTE: The quantity of primer required varies depending on timber density/absorbency and the application method. Hard timbers (e.g. Teak) absorb less primer than soft timbers (e.g. Oregon). Brushing the primer on before removing excess material with a rag will use more primer than applying as per a rubbing stain but can give a more desirable result. Anticipated Cure Time at 77°F/50% R.H: 8 hours touch dry; 12 hours hard dry

Recommended Coats: 1 coat (1 application). It is recommended to continue primer application until timber saturation is achieved. Once saturated, do not apply any more materials.

Recoatability: 12 hours minimum and 18 hours maximum using Awlwood MA Clear Gloss

Sanding at 77°F/25°C: All Awlwood MA Primers are sandable after 12 hours. Use P400 grit sandpaper for colored Primers and P280-320 grit for clear.

J3809/J7809/J9809 Primers: 500g/lt or 4.17lb/gl

Application Equipment

Brush and roller application. See pages 8–14.

NOTE: Preparation techniques and results will vary according to individual conditions, equipment age and other factors. Testing on a non-critical area should be carried out prior to full-scale preparation.

WARNING:

NEVER USE TEAK CLEANERS – oxalic acid residues impede proper curing of both primers and topcoats.

Surface Preparation

Any cracks in the timber should be epoxy filled or splined with timber prior to sanding. All previous coating systems must be removed. The surface of the timber should be mechanically removed until coloration is even and the original timber tone is exposed.

Sanding

• Timber must be sanded using no finer than P120 grit

• If timber is weathered, scrub with the grain using a stiff bristled wire brush and running water to remove all grey timber prior to sanding • Bare timber that has been saturated by salt water at any stage must

be scrubbed well with fresh water to remove salt deposits before commencing sanding.

• If timber gets wet after the final sand, water spots may appear. Re-sand these areas with P120 grit paper before priming. Applying to Resinous Timber

Any cracks in the timber should be epoxy filled or splined with timber prior to sanding. All previous coating systems must be removed. The surface of the timber should be mechanically removed until coloration is even and the original timber tone is exposed.

Filling Defects/Fixing Holes

Where possible, and especially for screw holes, wooden plugs of the same wood are the best solution for filling. Plugs should be fixed in place using an epoxy resin based glue, with care being taken to line the grain up. Any excess glue should be removed by sanding before priming. If this method is not feasible then use an epoxy resin mixed with dust/shavings (preferably from the same wood that is being coated). Once cured, these filled areas should be sanded and excess glue removed before application of the primer.

NOTE: This method may result in filled areas appearing slightly darker than surrounding wood due to the absorbencies of epoxy compared to wood. Use of a colored primer will help to minimize color differences. Always test on a small non-visible area first.

Mixing and Reduction

Awlwood MA Primers should NOT be reduced.

Application Instructions

General: Awlwood MA Primers should be applied in conditions between 4°C–30°C, with relative humidity of 30%–95%. Awlwood MA Primers cure by the mechanism of moisture in the air (humidity), therefore very low moisture content in the air will lead to longer cure times. Do not use this product in an air-conditioned environment. If Awlwood MA Primers is to be applied in an environment where it is suspected that low humidity will inhibit the cure of the primer, apply to a test area first.

General: Decant sufficient product for 30 minutes use into a roller tray or working pot. Seal the original container immediately to prevent moisture exposure.

Do not tip unused primer back into the can. Awlwood MA Primer Clear

Apply by brush or roller until timber is saturated. Do not attempt to build a film. On very deep grained timbers, do not flood-coat the grain. This will need to be filled using successive coats of Awlwood MA Clear Gloss.

Awlwood MA Red & Yellow

There are two application methods that can be used for applying Awlwood MA colored Primers:

1. Apply with a rag or staining cloth as if rubbing a stain, ensuring the primer is applied until timber is saturated. Do not attempt to build a film. This method helps create less mess if brush splatter (on decks etc.) is an issue.

2. Apply using a brush or roller. Working in sections of approximately 1m wide, apply the primer until timber is saturated and remove excess material as you go. This helps prevent excess primer becoming non-removable. Do not attempt to build a film.

Wiping off excess primer right down to the timber surface is key to achieving a natural appearance. If excess primer becomes tacky, apply fresh primer up to 15 minutes after application to re-dissolve. This will make the primer workable for ~5 minutes, depending upon application conditions. Wet edges must not dry for longer than 3 minutes before applying and overlapping the next section of primer.
