Wood Hardener for Rotted Wood 500ml - Repairs Rotted Timber | Fast-Acting Formula Reinforces Soft, Damaged Areas Before Filling or Painting

Wood Hardener for Rotted Wood 500ml - Repairs Rotted Timber | Fast-Acting Formula Reinforces Soft, Damaged Areas Before Filling or Painting

Q: Would you use this on the whole area

It's only required on the rotted area. Cover the entire rotted area, allow to dry then rub down.

Q: How long between applying coats?

About four hours. Longer if colder. If you are using wood filler allow about 12 hours after wood hardener is applied.

Q: Under the cap, there’s a little metal lid that seems to be welded on!! Any advice on how to take it off safely? I’ve tried a stanley knife but nope.

I used a screwdriver to prize it off. Not easy but don't worry about destroying the metal lid.

Q: Does this dry clear, or milky white?

It dries clear unless it gets wet before drying - then it is milky white - I found the same with the Ronseal product
