Does Not Work

Used this 12 months ago on new timber. Followed the instruction and applied two coats. Now the knots are coming through . Skirting boards and architrave's look awful. Will have to redo them all. Don't waste your money on something that doesn't work .
No wonder they've reduced the price

I used on a pine window architrave about 18 months ago. 2 coats applied. The knots are now coming through. Another case of B&Q selling unproven products that do not do what they say on the tin.
excellent value for money

Does what it says on the tin! 2 coats required for effective coverage.

I'm glad I bought this product, it saved me much time and effort, all done in one go. Wood knots treated, primed and undercoated in one. Good finish
