In this video I conduct an experiment looking at different ways to paint OSB to ensure a fine finish, but also to protect from discolouration of the resin bleeding through the paint. This part is the set up of the experiment, the different methods I have chosen to try out and the carrying out of these methods. I will return in a few months with Part 2 of this to show the results. I wll also post regular updates on my social media pages for those that are interested (links below).
As ever, thank you so much for your continued support in my disability woodworking adventures. Please consider giving the video a thumbs up and maybe even subscribing to the channel. Best Wishes, Leo

Here's one data point. I did a garage conversion with OSB walls. Painted with solvent/oil-based:
Leyland Undercoat 5 Ltr white (Screwfix code 63095)
Leyland high gloss white 5 Ltr (Screwfix 60193)
Both 5 Ltr cans are about £25-30/each at this point. I also painted with another oil-based overcoat, though I cannot remember which one.
Pros:
Absolutely rock-hard and durable finish. If you accidentally hit an object on the wall, I think you're more likely to scrape the object than you are the wall paint!
Cons:
Incredibly long drying times. Like, basically a full day to recoat, and perhaps even longer in certain conditions. Like all oil-based paints, they're a nightmare to clean up. So you want to be ready to wear gloves, and throw away any rollers you use, etc. Fumes are pretty bad.
I think for smaller jobs, you would be tempted to spend 2x the price and go with Zinsser, which is water-based. We'll see in this test, I suppose. If you have the space, and setup (gloves, disposable rollers, etc.) and time, then you may want to go oil-based.
It's hard because when I did it a year ago, there was so little info online about what to do with OSB. A lot of people (like myself) do it one way, and then don't have a basis of comparison.
Brilliant, thanks for this. I’m going to pin this comment to the top as it has loads of useful info in it. Cheers for posting, Leo 😀👍
I’ve just built a massive wrap-around workbench in my shed with osb and am looking to add a finish coat, this video series is perfect, thanks for your efforts man 👍🏻
Cheers, thanks for the kind feedback 👍😀
I've found myself here as I've a similar project planned over Christmas. Looking forward to the three month update as that's around now!
Thanks for experimenting for us, very methodical and nicely done
Cheers bp. I’ve not a lot to report back on tbh at this stage, if you email me at 75handicraft@gmail.com then I’ll send you a few pics through and some of my initial thoughts if you like? Cheers, Leo 👍
good to see you back on UA-cam Leo
Cheers pal 😀😀👍👍
Hi Leo, looking forward to the outcome of this one. I think it would be useful to see the OSB on a wall, with more even lighting. Great to see you on form. Hope your pain levels have improved and you’re pacing yourself. 👍🏽
Thanks Mandy. I’m going to try and get the sheet up on a wall. Bit easier said than done with the electrical ducting but I’m sure there is a way ! 😀
My 2 pennies for what they are worth, Zinser products are overpriced and won't hold back tannins but ok as a sealer for porous surfaces, oil/spirit based undercoat will outperform zinser for holding back stains and will also seal porous surfaces. don't use emulsion as it will get grubby very quickly when touched, always thin your first coat if you want it to penetrate and not flake off. masonry paints are more washable and durable and fine for indoors even though it's an external paint. all oil based products will eventually go off colour. All of these will look fine after a few months, we tested half a dozen external paints over 7 years in a damp environment and Sikkens was the only one that lasted the full 7 years. I do enjoy test videos, very informative
Brilliant pal, cheers for the feedback here, as ever much appreciated 😀👍
What I want to know is how the heck did you manage to open a paint tin or one of those awful plastic tubs with only the use of your non-dominant hand and not end up with it all over the gaff and yourself? I have two hands and struggle to keep everything clean. You never cease to amaze me Leo even with what you may consider to be small things like that. Interesting video too mate. Will look forward to the update as it arrives. Please keep well, love your channel. 👍
Thanks Kev, very kind of you pal. Funny you say it as I’ve never really thought about those paint lids, I have more of an issue with the ‘traditional’ ones😂😂
That sanded panel 2nd from the left. 2 coats of masonry paint? Bang for buck that looks good now. Interested to see what it looks like in a few months. Putting up reclaimed OSB to create a pocket for my sliding shed door so I can take my mitre saw off a mobile bench & onto a fixed one with a bunch of drawers underneath and use the dead wall space the slider takes. Thanks Leo.
Thanks Denis, yes two coats of masonry on that panel. Tbh they all look great now, but I’ve no doubt there will be changes in the coming months👍👍
@@Hand-i-Craft Sunlight could have a huge & interesting influence on the results too, Leo. Not that we’re going to have much more this year. Anyway, I’ve only recently come across your channel, probably through Peter & Keith. Loving it. KUTGW👍
I'm currently working on osb to put into a bathroom. I'm using osmo white oil and scraping it on. Because it's in a bathroom I've only lighty hand sanded it down as I didn't want to lose the factory coating to much.
I've used Osmo white oil scrapped into the boards pores so it fills up the gaps and takes the woody look a bit down. I didn't want to mask the wood bits too much. When it's dry I will put on two coats of Osmo Wood Protector, as it will be in a humid environment. The only concern I have (a little) is that I've used the board in reverse. The wife is the arbiter of taste and I at all times follow her design sense!
Is it a good Idea to seal the back of the boards as well, but they will be screwed on to the walls. These boards are not used in the shower wall in any way.
Thanks for the message. In regards to the back of the boards, will all the effort you’re going to on the front of them I’d say it’s worth putting a coat of primer / sealer on the back 👍👍
Thanks, good point...More work!!😂
Very helpful thanks, liked and subbed :) Noticed someone mentioned your pain levels, did you injure your right hand ? Hope it heals quickly pal. I'm making an outdoor storage box for garden stuff and didn't want to sand and will be using outdoor paint over the primer/undercoat so this is great, thanks :)
Thanks Gary. I was in a car crash 5 years ago and suffered nerve damage resulting in losing the use of my right arm and hand. Also have to live with chronic nerve pain as a result
@@Hand-i-Craft Sorry to hear that pal. You can go to your doctor and request medical cannabis in the UK now, there is also Sativex, licensed medical cannabis, and it can be very good for chronic nerve pain and doesn't get you high.
@@GaryMcKinnonUFO Thanks Gary, I’ve just had pretty major surgery where they placed an implant on my spinal cord to help with the nerve pain. I’ve got a video on the channel about it if you’re interested 👍👍
@@Hand-i-Craft Ok thanks, i'll watch it.
Hi Leo,
Watch your video and loved it.
But I do have one question mate, I was wondering why you didn't consider the use of say Leyland acrylic primer?
Cheers Ed, just catching up on some comments. I did make a reference to it somewhere in the middle of the vid, I forgot! Even though I’ve got a tin of acrylic primer undercoat. Going to find some more OSB and add it to the collection 👍👍
Very interested to see how this pans out. I have an idea but I've usually been wrong in the past. Particularly interested to see how water based sits on top of oil as I have some windows that need reviving and top coating and I'm trying to avoid oil paints but need the oil to go into the wood to nourish them first. Any suggestions, I'm all ears...
Me too Ben in terms of watching to see how it progresses over time. My method with the Zinnser bullseye worked great but interesting to see how the others cope 🤔🤷♂️
If you're doing windows, give them a good go with some linseed oil before priming/painting. It really helps
@@bpmills222 Thanks for the advice, that's what I hope to do this summer, but how well does the water based primer sit on top of the linseed oil? I use Leyland primer as a rule. How long did you leave the oil to cure before priming?
@@benjaqsonworkshop9974 we went for oil based primer on top and a oil "satin" gloss
I'm trying to move towards water based products where I can but as your comment suggests, oil paints still seem to be the most effective. It will be interesting to see how Leo's results turn out.
Current cost of plywopd is about 95usd. Which is why I'm here.
Thought it might be, thanks Henry 👍👍
Nice one, Leo. Does the writing on the OSB indicate a face or backside? Cheers Pal.
I’m tempted to say yes Wil, but I’m not sure as it could be purely random. Has got me thinking though
👍👍👍
😀😀👍👍
I'd be curious if they'd pass a packing tape test, stick some on, pull it off and see what comes off. Almost like waxing, not that I'd know what that is like 😏
Interesting question, how about I do this as part of the follow up in a few months?
@@Hand-i-Craft that would be great! Let's see if it screams like Steve Carell 🤣
Did the emulsion cover over the oil based primer
It did Rob. As it stands though they all look good but I don’t think it’ll be like that for long!
Paint then hang, or hang then paint?
Personally, hang then paint but that’s because I often bump and bang things so it would need a load of touch ups if I painted first then hanged them 😂😂😂
What grit sand paper did you use?
120, but 80 would also be fine 👍👍
would it be a better to apply using an electric sprayer?
I’ve tried spraying masonry paint and I have a video on my channel about it. Personally I wouldn’t recommend spraying masonry paint due to how much you’d have to thin it down to be able to spray. Emulsion you could spray, but again it requires a thinning down process. The purpose of these videos was to compare different products right next to each other and spraying would have just added another layer of complication 👍
Where’s part 2? It’s been 4 months???
There is a mini update in my recent vlog video Richard if you want to have a look at that 👍
update?
There is a brief update in my channel vlog video Andrew and I’m going to leave it a bit longer for a full video update 👍👍
Whats wrong w your arm?
I suffered nerve damage from a car crash nearly six years ago Tracey and as a result lost the use of my right arm and hand
why is hesh its hand hidein in its overalls
I suffered nerve damage and lost the use of my right arm nearly five years ago in a car crash Craig
Dude, get your hand out of your pants!!!!!
I don’t think you realise but I don’t have any use of that arm and hand, suffered nerve damage nearly six years ago and lost the use of my right arm
