The invention provides methods for producing flexible, stretchable, and/or elastic products comprised principally of material such as natural elastomers and other synthetic polymers. The method for producing stretchable products by spraying product material over a workpiece former, and method for creating perforated products by spraying product material over fibres in an upright position. The invention provides methods for making double sided fibre coating of the product and, or to at least coating the product surface on the side facing the wall without the need for removing the product from the wall.
