Window sill made of MDF Moisture-resistant V313, by Jan

Description by Jan

Make a windowsill with MDF 15mm waterproof from TOSIZE.se. Measure with a tape measure and mark the desired dimensions with a pencil and square square. Cut the MDF accurately to size with a plunge saw and sand edges smooth (grit 120-150). Apply primer to all sides and let dry. Because the plate was too short, I made the windowsill from 2 parts and filled the seams. Sand lightly between coats. Finish with desired final paint for durability. Use brushes for an even finish.
