Pre-primed white MDF (Medium-density fibreboard) skirting boards are resistant to splitting, warping, and twisting. MDF skirting adds an environmentally friendly characteristic to your home, as the boards are created from recycled offcuts, sawdust, wood chippings, and trees that aren't suitable for other uses. Fitting skirting boards in your home can help conceal the unpleasant joint where the wall meets the floor. They can also protect the area from feet and furniture knocking the targeted area on passing.
