15 Yr Old Thomson's Water Seal Still Usable?

Dec 16, 2006 Last reply: 1 year ago 18 Replies

Hi and Happy Holidays,



I have a 5 gal can of Thomson's Water Seal that is at least



15 years old. Is it still usable or should I get a new can?

I would just replace it but getting rid of the stuff nowadays is such a pain in the neck.



Thanks, Gary


If it is not thickened, it is still good. OTOH, it was not the best water sealer to start with.

It's just petroleum wax dissolved in mineral spirits. If it hasn't gotten gummy, should be fine. Not that it's worth the effort to grease your decks.

As they said the stuff is almost worthless when new. But it may be easier to dispose of by smearing on your deck than any other way.

Best way to get rid of it until he gets a better sealer, like Cabots.

as others have stated....... it was not the best water sealer to start with.

If thickened or lumpy....swirl the container & pour a small amount into a clear container...check consistency

if thickened it can be restored to "new" conditon by heating...use flameless heat source (heat gun)

better to use it up than create toxic waste

cheers Bob

Yes it can be used, although Thompson's water seal is a below-average product.

It wasn't usable when it was new. The poorest brand of waterseal on the market. Throw it away.

Me and friends have used much thompsons, I believe it works GREAT! stopped all concrete detorioation around here.

the trouble is some people spray a mist on like cleaning a window, then wnder why it didnt help.

like painting a wall with too littkle paint then wondering why it doesnt look good:(

Find someone, somewhere to take it off your hands. I put that crap on my deck 18 years ago failing to realize that the wood would still require frequent cleaning to maintain the 'real' wood look (yea, I know - not very real). I decided to stain it with Cabot's Barn Red semi-solid )or semi-transparent) stain after the fourth year. To this day, what little of that stain remains on the wood will rub off on your clothing with the slightest touch. Now that I have g.kids they are all over that deck too. Run away from that crud! I've been told that the wood will never take any stain again because of it. If anyone else knows of a cure for this

**please** let me know via the UN or my e-mail. This is one topic that really jacks me up, if you couldn't tell.

Just answer the question do not advertise another product!!!

Should be ok as long as you can make sure it is not separated chemically. I’d shake it up and do a test apply on a scrap piece of wood,let it dry and water test

What good brand of sealant can be used with paint sprayer?

VOC rules changed the formulation and I was years ago that I tried a garden sprayer and it would not work as it clogged. Should be OK with a roller or brush.

I'm not sure but will ask in the handyman group locally.
