Abstract: The agent of a biological paint, such as of the paint sold under the trademark Bioboya, is a mixture comprised of water, saccharose, animal oil and/or a root plant oil, vegetable oil, wet wax, clay and silicon, into which a biological paint is combined according to the method. With an ecological indoor paint with the agent added, environmentally benign and safe properties are achieved: non-combustibility and biodegradability. Also, the paint with added agent does not produce gases and is suited, in addition to concrete surfaces, also to wood surfaces, metal surfaces, Styrox surfaces, gypsum board surfaces and plastic surfaces.

Abstract: The invention is concerned with a board product that consists of wood material, a binding agent that keeps it together and additives. The binding agent is water glass and the product furthermore contains graphite that works as a fire resistant material and as a substance, which increases the water resistance. The invention is furthermore concerned with a method of preparing a board, wherein the wood material and graphite are mixed well together. Wall paper glue is added to this mixture if such glue is used, after which the mixture is again mixed and dry water glass is added after which the mixture is again mixed. Water is added to get the desired rigidity of the mixture, with which it can be regulated and then the mixture is poured into a form and compressed to desired density.
