    Default How to fix wooden patio chairs

    Three of our patio chairs have broken after a few years of being exposed to the elements. The wood is very dry, despite using Woodoc 50 regularly over the years.

    I would like to try to fix them, but first want to see if I can "feed" the wood. We sandpapered some of the chairs.
    Attachment 526843
    I was thinking of use raw linseed oil and saw quite a lot on the internet about this. Any advice?

    What would be the best to try and fix the seats?

    All 3 chairs broke at the same spot

    Thanks for any help

    If you consider an oil, I like using the Mad Manny mix of 50/50 Woodoc 30 and Waxol which is diluted with another 10% diesel. I have wood cladding outside which I treat once a year.

    Thanks

    This sounds good. I suppose I will probably need to give a few coats of the mix and no other sealer as a final coat?

    How dark is the final product, as it looks as if the Waxol is quite dark?

    One last question-Do you have any idea what will be strong enough to keep the broken pieces of wood together? A metal bracket with screws?

    One coat at a time. It soaks in over time. It might be greasy for a while. Not sure if that is a problem on the chairs.
    Being weathered chairs, the wood might darken quite a bit.
    I cannot view your photos, so not sure about the damage.

    I also can't see your photos.

    Linseed oil in my experience doesn't really penetrate, but forms a hard crust on the outside. similar in concept to a varnish, but probably less effective at keeping moisture out. Not sure what would happen if you diluted it.

    Apologies..Don't know how this happened. The first photo shows 3 of the chairs already sandpapered.
    One can see the colour of the chairs quite well in photo 2, although it does need some oil.
    All the chairs broke basically at the same spot

    If the breaks can be pushed together I would try epoxy in them and beef them up with an auxiliary piece of wood neatly screwed in from below.

    As Plunger said-try to keep the splintered broken ends intact as possible so you can push them together again-best to do several dry runs to pick out any loose/misaligned splinters so you get a tight fit needing minimal filling afterwards.

    I would tend to use a foaming/expanding type wood glue for this-like Balcotan ( use the original brown standard-setting one-it will match colour of wood more closely than fast setting type)

    wrap in clingfilm before clamping as necessary for setting

    I think you may have to do some more sanding -you have to get all the wood to the same dry non-sheen surface -otherwise the oils you apply will soak differently, leaving a very patchy finish.

    Nice chairs8) -worth expending a bit of elbow grease on!

    Show us your finished chairs when done

    Yeah..I know some more elbow grease is needed.. I'm busy with the table as well. I took a picture just now, but because we had a few drops of rain, the table looks worse than what it actually is. A lot more sanding there needed as well.

    Regarding the colour, I plan to use Sawdust's Mad Manny Mix. I dont mind the wood getting darker, but is it not going to get too dark (like imbuia)?

    Thanks

    I would be very wary of using the Waksol on the furniture, and would use the Woodoc alone.

    -I have used it in the past ( but the original WAXOL brand -I suspect this one is similar in composition) -and it is primarily a product for fences, structures in constant weather exposure

    -the problem is that it remains tacky/waxy, and never really dries 'clean and dry' as you want for a dining/coffee table.

    Would be well worth doing an experiment sample -especially with the amount of elbow-greased prep involved

    Waxol is made for Wendy houses, not for furniture, I stays waxy for ages and your chairs will be unusable. The Woodoc on the other hand is made for finer applications and would be dry after a day or two and is a far superior product.

    After gluing the breaks as above you should inlay a reinforcing strip on the underside to prevent it breaking again either wood or an aluminium strip, just to reinforce

    I always wonder: Why do paint companies spend R000 to develop a coating for a certain application, just for some clever guy to bugger it up by using it in their own "special formulation"? Eish!! (We all know this scenario from people who want to improve the performance/efficiency of their vehicles - quite possible, but the long term results?)

    Use a product from a reputable manufacturer and stick to the product/application/method and you will have the best results. Your choice is between a varnish-based and an oil-based product. That's it!
    And yes, NO product will last forever, especially no outdoors! Outdoor furniture is HIGH maintenance!

    I have just used a product called Ultraseal from Timberlife in PTA on my garage door and outdoor furniture. Keeps soaking in and then sets with a beautiful finish.

    Thanks for the responses. It seems as if the consensus is to not use the Waxol.

    I've used Woodoc 50 in the past and I have still some left. I'm not sure what the difference is between Woodoc 50 and 30 (Which I've just bought).

    Will the Woodoc penetrate deep enough to feed the wood? When the one chair broke, it sounded like a very dry branch breaking.

    you may need to apply many thinned coats to get best penetration

    - warmed sealer on warmed wood will soak better

    -check their website for details8)

    That Marine varnish will look fantastic, but once it starts peeling and cracking, it will be one hell of a job to strip it. Rather used an oil based product for exterior use, like Woodoc 30. It disintegrates over time and you simply use steel wool to prep for a new coat. And it penetrates and "feeds" the wood. Or one of the Plascon Woodcare products, or Dulux Woodguard Timbavarnish. Although a varnish, it will be a loy easier than Marin varnish when it comes to prep for a new coat.

    If I understand you correctly, the Woodoc 50 is a varnish and the Woodoc 30 is oil based with better penetration. (I visited the Woodoc website, but it was hard to pin point the difference between the 30 and 50)

    Suddenly everything makes sense. I've been using Woodoc 50 all these years and I suppose it did not really penetrate and feed the wood as much as I wanted. The stripping is a major task! I suppose I can use Woodoc Furniture Wax for the initial few layers, before using Woodoc 30.

    That is obviously a weak point, it will break again.....

    I suggest that after it has been glued, add an unobtrusive length of mild steel flat bar UNDER that area, screwed in with decent wood screws.
