Review: Good quality filler! - This filler is especially good if you have larger areas to fill, but works equally well for small repairs. It dries very quickly as it's a two pack process with a hardener, so you also have to work pretty quickly or you will waste quite a bit. Don't mix up too much in one go. It's very easy to sand afterwards to a great smooth finish and has excellent adhesion. Works well with MDF as well as wood. It's a horrible smell but that soon goes once the hardener goes off. If you are painting the wood white afterwards the I recommend using the white version of the filler. Finally if you run out of the hardener and still have loads of filler left, if you hunt around you can find tubes of hardener for sale on their own.
Review: Good product - Does what it says on the tin. I have used this product for over 25 years and just works very well. I also use this for filling holes in plasterboard as it sands very fine and smooth. Mixes easily and provides a smooth filler that dries quickly. I would give 5 stars if the tin was reflective of its contents. Less than half full when new is such a waste of packaging and also very deceiving to the consumer.
