Bona Mix and Fill is a fast drying, waterborne gap filler which is mixed with sawdust to achieve a perfect colour match for filling gaps up to 2mm in wooden floors and fixing other minor defects. It can be used in conjunction with all Bona varnishes and primers and is suited to both light and dark woods. Once dry it can be sanded or re-finished. Please note that some rare wood species (typically tropical) or chemically treated wood have the potential to produce unforeseen reactions. In these circumstances it would be best to carry out a test first to establish compatibility.

We have a 30-day return policy, which means you have 30 days after receiving your item to request a return. To prepare the surface, firstly ensure it is clean, dry and free from wax, dirt or any other potential contaminates then sand the floor to bare wood with P60 - P80 grit abrasive and save the dust. Mix with the sanding dust to a smooth porridge-like consistency and apply to the area to be filled with a stainless steel trowel.
