An absolute must when preparing and painting indoor new wood.
This product was recommended to use as some newly fitted woodwork in the bathroom showed knots under the undercoat - despite undercoating again they still showed through. Used this paint on the knots and then painted again - this time no knots visible and the paintwork looks great.

Does the job
A little strong on the odour but covers well and after applying the top coats to a painted pine wood floor there has been no evidence of any resin stains so far. Seals the wood OK but does need the two coats recommended. A little thin tbh, but does the job.

Great knot primer
Used to repaint a door where the knots kept coming through. This worked well and was easy to use.

Time will tell if it works!
I bought this to cover knots that were seeping through the paint inside our summerhouse. Despite two coats of this and several coats of white paint they are still visible, though mainly textured shadows, not the yellowy sap colour as it was before. The paint smells very strongly so you want as much ventilation as possible. I found it to be quite thin and runny compared to other primers so you need to be careful to protect floors and other surfaces.
