3M’s comprehensive range of polyurethane seam sealers offer a variety of packaging and colour options for all your seam sealing needs. If you’re looking for a cost effective sealing method and are less concerned with wet on wet paintability and
faster processing times, this is the range for you. These products can be painted over once the skin is fully formed. This will vary depending on the
temperature you are working in but should be between 20 and 45 minutes.
