Rated 5 out of 5 by Theblacksheepsister from Best knotting and primer I've used Farrow and Ball knotting and primer solution is the best I've ever used. When I bought my house there were a lot of bare wooden pine doors and skirting, so when I wanted to paint them white the research said I would need a knotting solution to stop them bleeding through the paint. I've tried a few other brands before Farrow and Ball and they've all fallen short and bled through. I tried F&b on my bathroom floor and door and a year later there are still no signs of bleed through. I've since painted a pine bed frame and door and again brilliant results. It goes on perfectly, dries pink and has no smell and a tin lasts for ages. Well worth the price. I've since bought another tin to do all my other doors.

Rated 5 out of 5 by SR2908 from Best wood knot and resin blocking primer! I bought this product, on recommendation from Farrow & Ball , after I had some staining come through paint on my newly restored ( 200yr old) front door! I did think at the time, it was a bit pricey at £20 for 750ml tin, but its certainly well worth the results! It worked! 2 years on my front door looks great! It did exactly what it was supposed to. Since then I have gone through tins of this stuff as we've replaced and painted floors and had loads of new timber. etc.. But a little does go a Long way. Very pleased- thank you Fartow and Ball!
