MDF can be finished with paint or varnish - it should always be sealed in some way, not left bare. Consider 18mm thick MDF as a minimum and have supports no more than 500mm apart for all but the lightest load. When using 25mm thick MDF, the spacing of the supports can be reduced to 700mm apart.Likewise, people ask, how thick should Wood be for shelves?
Thickness and Sizes Use 3/4-inch thick materials for shelves and bookcase structure. If you're using hardwood solids, it's OK to boost the thickness to 1 1/4 inch for almost unlimited support. This type of shelf looks more like a mantel and is expensive, but adds the opulent look of craftsmanship.

MDF stands for medium-density fiberboard, which is an engineered wood composite made up of wood fibers. Both softwood and hardwood are used to manufacture MDF. Generally denser than plywood, this composition creates a stronger material for building. We use a veneer sealant to prevent water damage.What weight can MDF hold?

Fiberglass adds a lot of stiffness to the plywood, especially when it coats both sides.Are Floating Shelves strong?
