What is the coverage for one gallon?

Asked by Earl May 1, 2021
1
Answer

With my board fence, about a panel and a half.

Can this be used on a brand new deck built with pressure treated lumber?

Asked by Crackers April 23, 2021
1
Answer

I used this on a brand new fence that was pressure-treated but I put Olympic deck cleaner on the fence first. The key to using this stain is - you have to open up the pores in the woods so the stain will be absorbed.

Can this be safely used to seal the wood floor (thick plywood) of a chicken coop?

Answers

it can be used on decks and it worked well on my fence. I don’t think waterproofing sealant needs to get into the entire board substance to be protective

Can this product be safely used on the inside of raised bed planter boxes?

Asked by Randy March 26, 2021

Answers

Why not? Do it early enough, 2 months or so to let the stain soak in so it won't bother the plants, in case it might. Stuff grows up against my fence which was stained and will be again.

Which pump sprayer do I use? What kind of viscosity?

Asked by cb March 23, 2021

Answer

I used a Chapin battery back pack sprayer($150) and it worked much better than my 2 gallon pump sprayer. Chapin and perhaps some other brands also make pump back pack sprayers but i have not used them for this solution.

The 2 5 gallon buckets i used on a new fence, had more of a light honey tint to it.

Sealeant is NOT "clear"
As with so many other reviews that I wish I had read before buying this product (who expects something labeled “clear” to actually be orange!?), this sealant is NOT CLEAR. I don’t get it. I now have a kid’s clubhouse that is painted gray with a semi-transparent orange film overtop and now I have to repaint the whole thing because it looks horrible. There are other reviews like this from 2015. How is this still a problem? It is absolutely waterproof. But it's ORANGE not “clear”. xa

Very happy with this stain. It is very important to use a premium deck cleaner first! Before putting on the stain.

Ugh
Reads review of a different Olympic product but wound up with this one. ‘Clear’ is not a subjective word, and this is not clear but yellow, like wood glue. Turned my freshly planed redwood fencing into a muddy orange/red I’m very unhappy about. It doesn’t enhance wood grain like an oil but hides it under a pasty film. Too late now, never again for this brand. If you do get stuck with this, be sure your application is perfect, there’s no going back to even out coverage and any runs will be orange. I went to Home Depot for more Thompson’s oil seal, but no longer stocked and since HD put all the locally owned hardware stores out of business there was no other choice.

Excellent Golden tone
It took a long preparation to rebuild clean, sand and apply sealant to my deck. It has a beautiful look of natural wood. My wife and Ilikes be it.

Great finish
I read the reviews claiming this turned their wood yellow. Well, for me, it turned my boring redwood fence into a red and honey colored masterpiece. I applied two coats with a Wagner sprayer (about six inches away) and I’m thrilled with the result. It has a light sheen and completely repels water. The spray from the sprinklers just rolls off the fence. Be aware that this is not clear. It does have a honey tone to it, but it looks great.

Read the Reviews - THIS IS NOT/NOT CLEAR
As so many people have already written, this product is not/not "clear" and has not been for years. I wish I had read the reviews before I purchased this. We (as others have) assumed we would apply this golden honey colored sealant and it would dry clear. NOPE! In the end it's not horrible, but it's definitely not what we were going for. Why why why after so many years and so many complaints would they continue to label something as "clear" when CLEARLY it is not??? Have to give one star for that, regardless of the quality/value.

Works great..looks ok
This Olympic Maximum clear sealant works very good but although it is marked as clear it is light orangish brown color when applied and dried. If you want a sealant that works good but are not too concerned about the coloring of the wood, then this is for you. If you want to keep the natural look of the wood then DO NOT use the sealant! This will turn the look of your wood into an orangish brown color that I believe some people will highly dislike.
