Specialized machinery and quality materials go a long way in making flooring
projects smooth and hassle-free. Endless belt sanders leave an even finish because the
sanding belt is in continuous contact with the surface. With drum sanders, there is a small gap
where the sanding paper clamps to the drum, so it does not provide the same continuous
contact. Even using L-cleat nails instead of standard nails ensures a stronger grip, so floor
planks do not shift and creak.
