Ronseal CKS125 125ml Colron Knotting Solution

Found this very easy to use. Put a double layer on just in case but seems to cover well. No idea what the moans about lids sticking etc are about. Use the brush carefully and there is little mess. Wipe off thread when finished as you would with any screw lid and there isn't a problem. This from an incompetent perfectionist ! As far as I am concerned likeall Ronseal stuff I have used it is worth every penny.

It seems to have solved the weeping knot problem on our pine garden office, - not too smelly quite easy to use, apart from the attached brush attached to the lid which was a bit silly. Repainted a few hours later and it now there is no evidence of the previous problem. Happy with the product, does the job and goes a long way, - treated a 2M x 5M garden office and still have a half tin left.

Does the job on the tin

A little goes a long way. It seals knots to stop knots showing in your woodwork and prevents sap leakage that can blister your paintwork. Great idea having a little brush incorporated into the lid. Easy product to use. I only used about a quarter of the tin coving 1 metre high by 20 feet long to knot seal tongue and groove prior to painting (one application per knot). Time will tell if this has worked. I'll update this review if there are any issues.

Ronseal always provide quality woodworking sealents etc. This knotting compound goes on well and is quick drying.

Arrived leaking - but did what it was intended to do i guess. We failed to do this on a not so hot day on our newly sanded windows. We had a knot seeping through, scrapped it off and sanded it down then painted this on. Waited for it to dry - only to notice that the sap had come through, a few more attempts later it was ok.Our fault i am sure for not sanding the knot down enough - but we almost made a groove where the knot was.Does the job i guess.

I have used this for a long time on resinous knots in woodwork prior to painting. It appears to work well and certainly you see the effects if you don't use it. The brush in the lid is really useful and removes the need to clean brushes.One negative is that if you get any around the neck of the can and don't remove before putting the top on it sticks terribly and mole grips are required to remove it!

I had knots in the wood that were causing the paint to blister when applied due to the resin from the knots leaking. Rubbed down the knot areas applied then repainted, no problem since.
