Finishing

Once the filler is dry, wood can be over-coated with a suitable wood stain or wood paint.
Please Note: When over-coated the filled area may differ in colour to the surrounding area, therefore we recommend filling and finishing a test area first to ensure that the appearance is acceptable.

Super product
First class product that saves original profile. Quite expensive but with the cost to restore damaged wood material.

If I could do it, anybody can
Clear instructions, clean job, seems to work. How durable it is, only time will tell.

Good filler
I’ve used this before in conjunction with Cuprinol wood hardener and it seems to adhere well and flex. Add a bit too much hardener and it starts to set very fast but if you get the proportions right it is workable for long enough. A bigger colour difference between the hardener and filler would make it easier to see if it is properly mixed.

Easy to use
Saved a lot of money, and served its purpose.great product

Easy to use, wear a mask as fumes are strong
Easy to use, dries quickly, sands easily. Best to build up in two or three layers if a deep repair, allowing it to dry between layers. Should provide a lasting quality repair that is tougher than the wood itself..

Always been a good product
Used this product for years do make sure you use wood hardener first on poor timber
