Reviews
Colron Knotting Solution 125ml is rated 4.2 out of 5 by 17.
Rated 2 out of 5 by from Faulty lid won't open Bit of a mix up after no one let me know item was ready to collect, but then I got through on the phone and was told it was ready. Unfortunately the 'child safety' screw top cap wouldn't open and there wasn't another one for me to exchange it so I am waiting for covid lock down to end so I can get a refund.

Rated 4 out of 5 by from Self contained, self explanatory. Used this today for knotty pine wood. So can’t give a realistic reliability review.

Rated 4 out of 5 by from Seems to do the job - will wait a year Good stuff - only just gone on so don't know if going to work but will try to remember to repost. Going on easily enough, brush in included and attached to the lid, so no cleaning up etc - just put on and do the job.

Rated 5 out of 5 by from Does the job Used this on a new door frame three weeks ago. Easy to apply and I haven’t seen any problems since painting. Although it’s a small tin, a little goes a long way so I have plenty left for another time but just need to make sure I don’t loose it!

Rated 3 out of 5 by from Time will tell Easy to apply but time will tell if it works, hence 3 stars

Rated 2 out of 5 by from Good - BUT brush detached, tin bad to open The Knotting is very good - a lot more than can be said for the brush attached & the tin. Brush fell off into tin 2nd time we used this, two days later the tin would not open at all. We have now managed to cut off lid and have stored the knotting in a glass jar.
