Spraying Thomson Water Seal

[Wayne - Oakville]

I have a couple of small decks made out of outdoor wood and some old Thomson Water Seal that might as well be used on the wood. Is there any reason that I cannot use my weed sprayer to apply the sealer, and then brush it in? I see that the stores sell special sprayers for this type of thing, but since the sealer is very watery, shouldn't it work? Will it leave residue that would later by harmful to my trees or grass (depending on which sprayer I use)?

Thanks.

I can't see any reason this wouldn't work, as long as the bottle of the sprayer is well rinsed out. But I think it would be quicker to put the thompsons in a paint roller tray and evenly spread it out with a roller on a broom handle which you'd likely have to do anyway afterward to ensure overall coverage.

What a timely topic!

Today I cleaned my fence and deck, then purchased Thompsons with a cedar tint and proceeded to load it into my weed sprayer which is brand new. The spray was not nearly fine enough to get a nice consistant finish so I busted out a brush and worked on the fence. I will use a roller for the deck.
The company that makes my sprayer (RG flowmaster or something?) makes a sprayer specifically for applying stain. I figured it had upgraded o-rings (viton) and not much else for double the price, but maybe I was wrong and the nozzle is designed to provide a finer spray?

Thanks guys. I was wondering whether there might be some problem with the thickness of the sealer. I hadn't thought about the roller idea, but I've got some used but cleaned rollers that will work fine for this job.

My Thompsons says "DO not use a roller"....

That's only because the roller is toast after using thompson's on it. Ideal for $ store rollers or second use rollers after a paint job, then throw it away.
