Soft and blackened needs hardening and restoring

Post by XQSME » Mon Feb 22, 2016 1:56 pm

Good afternoon

I have a few patches of slightly soft wood....should I use a DIY shop wood hardener and wood filler or is there anything particular to suggest (on a budget) or any other ingenious methods.

Also , and I ams sure there is plenty of discussion about this , any tips to remove the black patches where damp has penetrated my Albacore?

thanks

Hi Tim

Can't comment on the wood hardener, but I treated the black patches on my Albacore with oxalic acid that a got from a fellow restorer in crystal form. You just put them a few at a time in a small amount of water and keep stirring and adding until they no longer dissolve. I then applied the solution to the dark patches over a couple of days with 3-4 applications and it took the marks out. I applied it using an old toothbrush, but make sure you use gloves and goggles as you need to protect your skin and eyes.

After treatment, make sure you thoroughly rinse the treated areas with fresh water and allow the wood to dry completely before applying varnish, otherwise the acid will stain your new finish over a period of time. It worked well for me.

If you have any solution left, make sure it is well sealed and labeled, because it looks like water and has no odour.

Hope this helps.

Graham

Thankyou both , a little worried by the frequent references to oxalic acid leaving a grey patch , any way of avoiding this?

I use ronseal wood hardener, as it is quicker to go off than the cuprinol one. Kind of fossilises the wood, though.

Oxalic acid can be bought on bee keeping sites as well.

The wood ends up very stiff and loose fibres go black. Hardens it, I guess, just like it says on the tin. Works wonders for solidifying bits before filling. Our Puffin was basically dead 7 years ago but I didn't want to make my daughter sad, so the inside is a large part wood hardener. I keep on expecting to hear a shattering noise one day, but so far, so good!

Just coming back on the question about grey patches from the oxalic acid.

In my case the answer is I didn't have any because I thoroughly washed the area after treatment. It is now 5 years since I varnished the boat and there are no marks where I treated the wood.

Hope this helps.
