Rated 5 out of 5 by from Just what we needed! Previous paint work spoilt by resin stains and build up. Door prepared and coated with this product, already seeing great results.

Rated 5 out of 5 by from Pure genius We paint stripped all the joinery on the front of our mid 18th century home back to bare wood. Had rotten oak (including a finial) repaired or replaced and new sills put on/in. And started again - I used three thin coats of this product on everything (4 on the new oak). Then three coats of undercoat/primer. Then three coats of Top coat (in Pointing exterior eggshell). This was 2010. South facing. Heat trap in summer and rural enough for hard frosts and icicles from the eaves in winter. This year is the first time Any of the joinery has needed a little bit of light sanding and repainting - just here and there. Am currently working my way through the north side windows that I did a rush job on a decade ago using a different brand surface primer (had used F&B paints for years - but I don't even know if this F&B wood knot/resin blocker was around then?). Going back to bare or or well sanded back surface this time and it's this product that is going on first. Same number of coats of everything. I probably don't need so many but given the outcome on the other side it can't hurt. I think this product is pure genius.

Rated 5 out of 5 by from Good base coat Having inherited a garage door, which oozed sticky resin, we were on the verge of burning off the paint etc. However, as I use Farrow and Ball paint inside the property, I decided to check out this problem and the fact sheet gave us all the information we needed to get the ideal finish to our door. A sanding down of the door was all we needed to do. The product is very good and instead of just covering the areas of knotting and resin eruption, we did the whole door. Wonderful conclusion to a unsightly problem.

Rated 5 out of 5 by from Simple and effective This product was easy to use and the pink colour, when dry, made it very easy to ensure coverage when applying the light tones undercoat.

Rated 5 out of 5 by 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!

Rated 5 out of 5 by from 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!

Rated 5 out of 5 by from 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.
