Surface coating - STYROFOAM®

PS stands for expanded polystyrene and is usually referred to as Styropor®. The material has a very light weight and can be easily shaped into the desired form by milling, sawing or hot wire. The surface of EPS/Styropor® is open and not resistant to moisture, so objects made of this material are not suitable for outdoor use without a coating. Styrofoam surface can be easily painted, coated or laminated, which increases its durability and stability and extends the range of applications. As a rule, styrofoam and hard foam models are intended for further surface coating by GRP/CFRP in hand laminate process or special painting. In the following table we present some possibilities of surface coating with their advantages and disadvantages.

	Styrofoam object without coating The desired object is milled by machine according to 3D data and the Styrofoam surface is kept uncoated. This variant is inexpensive, yet not well suited for outdoor use and repeated use.
	Coating Polyurethane The object is coated with a 2-component and solvent-free polyurethane coating. The coating is very UV light stable, high gloss, fast drying and available in RAL & NCS. This unique coating is color fast and is used in interior and exterior applications.
	Coating Epoxy The object is poured over with an epoxy resin. The material can be poured or painted or trowelled over various surfaces. After a few hours, the material hardens to a very hard and resilient plastic that can be easily sanded and painted. It is classified as flame retardant according to DIN 4102 B1 and is suitable for indoor and outdoor use without hesitation.
	Coating casting-laminating system The object is coated with a liquid 2-component casting and laminating system. It consists of a combination of liquid water-based acrylic resin and mineral powder. By varying the base materials used, materials with a wide variety of properties are created. Molded parts made of this material can be demolded and machined after only 40-90 minutes. It is weatherproof, UV-resistant and suitable for indoor and outdoor use. The material cures without shrinkage under low heat generation. Light, thin and very strong laminates can be produced by layering or laminating with glass fiber scrim.
	Coating Adhesive primer/filling paint/brush with texture The object is coated with a primer/adhesive primer based on acrylic copolymer. Filler paint is then applied with a brush. Filler Paint is a water-thinnable acrylic paint with a very high solids content and extremely high filling power. Suitable tools are used to give the surface a texture and then a metallic paint is applied.
	Coating Adhesive primer/filling paint/brush without texture The object is coated with a primer/adhesive primer based on acrylic copolymer. Then Filling Paint is applied smoothly with a brush. Filler Paint is a water-thinnable acrylic paint with a very high solids content and extremely high filling power. Finally, an appropriate metallic paint is painted.
	Coating Adhesive primer with gun The object is coated with a primer/adhesive primer based on acrylic copolymer. The primer is applied with a gun and then painted with a metallic paint.
	Coating with GRP (fibreglass plastic) The object is first painted with a solvent-free two-component coating compound based on polyurethane. Then covered with several layers of fiberglass soaked in the resin by hand (hand laminate method) in layers. After curing, the surface, sanded, filled and painted with as desired. This surface is particularly smooth, strong and weather resistant.
	COATING WITH POLYUREA The material polyurea impresses with its properties of flexibility, wear resistance, water and weather resistance, as well as very good chemical resistance. The two-component polyurea system usually reacts very quickly, which is why this material is always processed mechanically with 2-component mixing systems. read more

The final design of the surface is done according to your wishes and color specifications. You can choose from the entire range of RAL colors up to metallic effect paints.

However, the quality and cost of a paint job vary considerably. In order to apply the optimal coating and painting, the location and purpose of your object should be considered in advance.
