Firstly, don’t give up on your deck, no matter how dull and grey its gotten, no matter how many layers are peeling away. You CAN fall in love with your outdoor space all over again.
Secondly, don’t add another layer of stain until you’ve read this. Proper prep is THE MOST important part of a great finish. About 95% of finish failures are due to improper preparation. Stains require a clean, sound surface to penetrate – free of dirt, dust, grease, mildew, loose wood fibres, mill glaze and barbecue sauce. So don’t skip the prep step. Work with a cleaner that’s made for your deck in particular.
Take the Droplet Test
Sprinkle some water onto your deckboards. Does it bead? If so, then the water isn’t penetrating the wood–and neither will your stain. You’ll need to clean, sand or pressure wash to get to the original wood fibres so there is something to absorb the stain.
Grey, Weathered Wood?
So you haven’t touched a deckboard since the deck was built, and there’s green mould behind the garbage bucket you’re fairly sure science hasn’t discovered yet? You need RESTORE. Use RESTORE to remove dead wood fibres, heavy mould or mildew. Pair with BRIGHTEN to finish the job, and you’ll be amazed by the transformation.
Already Stained Wood?
Brand New Wood?
“Mill Glaze” is found on all new wood, and it interferes with the adhesion and penetration of stain. Benjamin Moore’s specialized cleaner, BRIGHTEN, will remove this mill glaze. Sand with 80 grit sandpaper to give your boards the extra “teeth” required for the stain to penetrate.
Benjamin Moore Cleaners are a concentrated formula. One gallon of cleaner actually makes 30 litres of cleaner.
Tools for the Job
Use in conjunction with a Pressure Washer for best results.
While a deck broom will do the trick, try the 12″ Soft Grip Steel Wire Scrub Brush, which has a little more bite and a threaded handle for use with extension pole (or broom handle!)
Also, don’t forget:
- Latex Gloves
- 5 gallon bucket
