What is Awlwood Satin Matt and why choose it?
Awlwood Satin Matt is an exterior clear wood finishing system designed to be used as the final satin matt coat over a fully built Awlwood Gloss system. It is a single-pack, moisture-curing coating that bonds directly to the wood structure through the underlying Awlwood Gloss, providing extended exterior durability and maintaining a natural appearance. With high theoretical coverage, controlled matt finish and a robust, professional specification, it is suitable for both industrial and consumer use on interior and exterior wood surfaces.

Applications and use cases
- Final satin coat over Awlwood Gloss: Designed to be applied only over a fully built system of Awlwood Gloss as the final coat, once the gloss has cured sufficiently to sand without clogging the paper.
- Exterior woodwork: Suitable for exterior clear finishing systems where a satin, low-gloss appearance is preferred while maintaining the natural timber look.
- Interior wood surfaces: Can also be used on interior wood as part of the Awlwood system, providing a durable satin finish compatible with Awlwood Gloss.
- Brush/roller application on large flat areas: Rollers are recommended for efficient coverage of larger planes, with limited tipping only if required for defoaming.
- Sprayed finishes: Can be applied by air atomized spray gun in controlled, dust-free environments for an even, professional satin finish.
Surface preparation (over Awlwood Gloss)
- Apply Awlwood Satin Matt only over a fully built Awlwood Gloss system.
- Allow at least 12 hours after the last coat of Awlwood Gloss (longer in cold conditions) before applying Satin Matt.
- Confirm that Awlwood Gloss sands readily without clogging the abrasive before proceeding.
- Hand sand with P600 grit paper, working with the grain, to produce a uniform dull surface.
- Avoid sanding through multiple coats of gloss. If this occurs, apply another full coat of Awlwood Gloss and resand carefully.
- After sanding, remove dust by vacuuming and then washing with warm water using lint-free cloths until the surface is clean. Tack cloths are not recommended.
- If contamination is suspected, solvent wash using the two-rag technique with Awlwood Brush Reducer or Awlwood Spray Reducer before and after sanding.
Application guidelines
Brush and roller
- Use quality foam or mohair rollers well loaded with product to minimize foam entrainment.
- Brush edges and corners that cannot be reached by roller before rolling larger areas.
- Apply at 12 m²/L on horizontal surfaces and 16 m²/L on verticals.
- Use synthetic bristled brushes with tapered, non-flagged tips if tipping is required.
- Aim to minimise wet edge times and do not overwork the surface; the coating will de-foam and level by itself but tacks up relatively quickly.
- Clean brushes and rollers thoroughly before applying final coats to avoid debris transfer.
Spray application
- Suitable for application by air atomized spray gun.
- Recommended conventional spray setup: fluid tip 1.40 mm (55 thou).
- Ensure a dust- and contaminant-free environment when spraying.
- Apply a mist coat if required to assist vertical hold-up, followed by a cross-sprayed full coat or a single cross-sprayed coat giving two passes.
- Do not leave product in spray pots between coating applications.
Coating maintenance
- Do not cut and polish or wax Awlwood Satin Matt.
- For cleaning, use warm water with detergent and a soft bristled brush, then rinse thoroughly with fresh water.
- Avoid abrasive cleaners.
- For stubborn stains, use only soft cloths and Awlwood Brushing Reducer or Awlwood Spray Reducer.
FAQ
-
Can Awlwood Satin Matt be used on bare timber?
No. It should only be applied as the final coat over a fully built Awlwood Gloss system, not directly on bare wood.
-
Do I need to thin Awlwood Satin Matt before application?
No. The product is supplied at a suitable viscosity for brushing, rolling and spraying directly from the can and must not be thinned.
-
How long should I wait after the last Awlwood Gloss coat before applying Satin Matt?
Ideally wait at least 12 hours. In colder temperatures, more time may be required; the gloss should sand readily without clogging the paper before applying Satin Matt.
-
What sanding is required before applying Awlwood Satin Matt?
Hand sand the cured Awlwood Gloss with P600 grit paper, working with the grain, to obtain a uniform dull finish. Avoid sanding through the gloss layers.
-
Can I use Awlwood Satin Matt in very low humidity or air-conditioned areas?
Low humidity slows cure significantly. The product should not be used in air-conditioned environments; in low humidity, apply to a test area first.
-
Is Awlwood Satin Matt suitable for application in full sun or windy conditions?
No. It is not suitable for application in full sun or windy conditions, as this may lead to uneven matting. Conditions should be uniform and well ventilated without localized draughts.
-
When can I sand Awlwood Satin Matt after application?
It is sandable after approximately 12 hours at 15°C, 6 hours at 25°C, and 4 hours at 30°C.
-
How long until the coating reaches full abrasion resistance?
Full abrasion resistance is typically achieved after three to four days of curing.
-
How should I clean tools after using Awlwood Satin Matt?
Clean application equipment with Awlwood OT0200 Brush Cleaner. Ensure brushes are then well rinsed with Acetone, Awlwood Brushing Reducer or Awlwood Spray Reducer before re-use with Awlwood Satin Matt.
-
Does the appearance change after application?
Yes. Awlwood Satin Matt requires overnight curing to fully flat down, and the appearance often continues to improve over the next few days as solvent is released.
