Hi all, need some help. I've just laid a new floor of old softwood boarding which had been previously painted. Stripped it and sanded it to get all paint marks off. Then filled old holes and splits with PVA mixed with sawdust . Put on first coat of Granglaze (oil based) and all the filler marks show through. Any suggestions on how to get a more even finish. I don.t mind staining the floor a darker colour. I,ve tried Danish oil and also wax polish on different parts of the floof but filler still shows through.
