Not quite 5 stars Excellent quality product and great info available from the F&B website. I wouldn't use any other floor paint having used it twice now with excellent results. First time I didn't use the F&B knot and resin blocking primer and the wood knots show through (although it doesn't greatly detract from the floor). So using this is advised. Why not 5 stars? Why such a massive tin of paint F&B? You don't need much of it for patch priming but it only comes in relatively large tins. So I have way more than I need. 29 December 2014
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! 03 March 2014
Superb and did you know ...... Superb product and to the best of my knowledge the only water based stain blocker on the market by a heritage type brand ( ie zinsser 123 etc but they do little to match little greene and F & B for topcoats) Inshort - if you use this primer then F and B undercoat followed by 2-3 topcoats of F anB estate then you can't really get a better/ tougher finish! Superb. Use a decent brush though! 21 September 2013
Really does do what it says on the tin I used this as a primer on my garden shed before the undercoat. It goes on very smoothly and provided a good base for the undercoat. I found that an overall application (rather than just on any knots in the wood) gave the best result. 06 July 2013
Excellent A pleasure to use. Great results. Good coverage and fast drying. 15 June 2013
Amazing stuff I couldn't believe after just one coat, all the knots and resinous areas on my timber were completely covered and sealed. Since using this paint I have had no problems with the knots showing through. Very happy customer here. 31 May 2013
