    I bought a tin of this, the paint has done exactly what I wanted, we painted new wood years ago and the knots have seeped and we have brown spots on our woodwork, this has completely covered the stains up. The tin however, is really flimsy, the lid has just completely bent rather than be prized open. Very poor quality for the £12 we paid.

    Doesn't do anything it's says on the tin. Waste of time using it.

    Regret buying - 3 years ago

    Used this product on a whole house refurb, All brand new woodwork throughout doorframe doors the lot. Knots are bleeding through and paintwork now looking yellow and streaky due to wood showing through. Awful product. Now have to repaint a whole house in less then 9 months.had to give a 1 star rating to give a review when in reality it deserves a minus 5

    Poor opacity so requires 3 or more coats to cover reasonably well i.e. not really an undercoat. Has then worked to block knots though. Most annoying is the poor quality tin lid. On subsequent use the lid lip just bends and the lid requires pliers to remove!
