Q: Can this be applied to extremely dry pressure treated wood?

2 months ago
1 Answer
  • A: Yes, Before you apply Seal-Once Marine Grade , you must clean and brighten your wood using Seal-Once Multi-Surface Cleaner. Apply the cleaner as directed. Let it sit on the surface for around 20 minutes. During this time, agitate it with a scrub brush. The scrub brush will help immensely. Do not allow the cleaner to dry on the surface. Keep it wet. Rinse off the cleaner with a power washer. Keep the wand about a foot away from the surface. You don't want to scar the wood. Your goal for cleaning is to make the deck floor look like it did when it was brand new. Complete raw wood. After it is clean and dry, (2 days), you can apply the required 2 coats of Seal-Once Marine Grade with a brush. Apply 2 thin coats. If you spray or roll, you must immediately brush the area using a brush. It is called back brushing. Do not spray or roll and leave it, you must back brush it immediately after spraying or rolling, using a brush. Brushing is very important. You begin at the end of two boards. You will brush to the other end of the same two boards. Now apply a second coat to the same 2 boards. Apply the second coat within 5-10 minutes of the first coat. The second coat must be applied while the first coat is still wet. (Wet on wet application). I live in Dallas. I have timed the first coat drying in 5 minutes. Push the product into the wood with the brush. Spread it out evenly and not too heavy. More is not always better. Do not allow it to puddle. Wipe off any excess with a rag. This way, you never walk over wet product. Three things to avoid during application: 1. Waiting too long between the first and second coat. 2. Do not apply too heavy. (Apply thin coats). 3. When applying the second coat, if you can't brush the product into the wood because there is too much, don't leave it on the surface thinking it will magically soak into the wood. The wood is already saturated. Wipe the excess off with a rag. If you don't wipe off the excess, it will leave un-even shiny sticky spots that will attract dirt and mildew.

Q: Does it perform well on outdoor furniture. Seats and arms on Adirondack chairs.

4 months ago
1 Answer
  • A: Seal-Once Marine Grade is made for softwoods like pine, redwood. For hardwoods like teak, oak, IPE, acacia, you need to use Seal-Once "Clear Waterproofer". Most furniture sets come already stained or sealed from the factory. You cannot use Seal-Once if it is already stained or sealed. Typically outdoor furniture, will look like it needs to be cleaned and coated annually, including Seal-Once. Seal-Once products are exterior penetrating, non-film forming water proofers. No film and little to no sheen. When applied and dry your wood will look like you did nothing to it. Your chairs will still look like raw un-finished wood. Seal-Once is made to repel occasional rain water. It will not repel, body oil, food grease, cooking oil, fruit juices, alcohol, or strong cleaning agents. Seal-Once products must be applied to raw bare wood. You must completely strip off any current product. If any remains hidden deep in the pores of the wood, Seal-Once will not penetrate, leaving un-even shiny sticky spots.

Very good product for wood

10 days ago
The wood finish applies smoothly and evenly, allowing for excellent coverage with minimal effort. It’s consistently is easy to work with helping the brush glide across the wood surface without leaving noticeable streaks or brush marks.

Revitalized an old picnic table

14 days ago
Really soaked into the wood, as i was hoping. No fear of a peeling coating. After a sanding and a couple brush coats of this product, the table looks nearly new again.

Yes, I recommend this product.

Disappointing

26 days ago
I bought this product for my pressure treated lumber outdoor furniture. I power-washed the furniture, let it dry, then sanded it and cleaned off the dust. I applied two coats of the sealer, and it let it sit under cover for three days so it could dry. It looked great...until it rained. Now some of the wood is grey and some has retained the finished color. Very disappointing for the time invested.

It’s nice!

We used this up north at our cabin on the lake. It worked so well! We just redid our stairs after the winter and this stain was very easy to go on and covered a very wide range of the steps! It went on easy and was not hard to prepare and did not take too many tools to do.
