DIY - Deck staining/protection
« on: May 13, 2019, 10:21:47 AM »
My deck needs treatment/protection.

2 years ago I used a Thompson clear sealer and now that I have read more and more the more confusing it gets.

I don't want to use something that needs sanding down the line or anything like that. I want the wood to absorb it, not a coating like paint that can peel off or that i would need to power wash it off or something.

With this in mind here are the 2 Thompsons type of deck sealers/oils :

One is stain+sealer (what I used last time but just clear) and is water based... The other one is oil based.

Which is better?



Also should I go to another brand or something?

In my country, Bona oil is usually the go to for any decking from what I have read.

Any help would be appreciated

Personally I like clear stain for a deck. Otherwise the high-traffic paths will show where the stain has worn down. YMMV.

My favourite for siding/eaves/etc. is Cetol, which is not clear at all though.

Personally, I would go with the oil based finish only because I have more experience and more faith in it, but again, there may be advantages to the water based that I am just not aware of. Watching intently since I have fences waiting for me too.

yeah i wouldnt go dark at all. just a semi transparent and closer to the pine hues as well. Like Honey Gold or something similar to those tones.

I think the All sealer from thompson even though is water based supposedly it still is absorbed by the wood. I remember paddehat, a user from the forum, recommended it to me at the time but after i read some more not sure of all the options.

Being the frugal that I am, I hate paying big $$ for something i can get cheaper.

All those deck cleaners and brighteners are just basic chemicals with a branded stamp.

From my reading they are all either SH (bleach) or something similar. I have read contradictory arguments for not using bleach on wood... in either case I bough Sodium Percarbonate (active ingredient of OxyAction - which from what I have read is what should be used instead of normal bleach (SH) ... and oxalic acid as a brightener and ph neutralizer.

Cost for 10 lbs of the stuff was $20 and it should be good for multiple uses

If anyone has any input regarding these cleaning solutions please let me know! All ears

20+ years ago I had a pressure washing business.  I stained & sealed a lot of decks.  I didn't like Thompson brand because it formed a waxy or sticky coating.  I preferred linseed oil based penetrants that soaked into the wood.  I used a lot of Olympic, but the best brand was CWF (clead wood finish) which was pricey.


I was recently shopping for a sealer for our boat dock & only found water based formulas available now.  I haven't researched sealers online, so I can't say what is the best product now.  But from past experience I'd avoid Thompson. 


Btw, the easiest application method I found was using a 2-3 gallon pump up garden sprayer.  A push broom works well for brushing it out if it puddles.  Choose a hot sunny day and it will soak into the warm wood better.
