Definitions
- This invention relates to a method for removing paint from a surface, for instance a layer of paint on a wallsurface on a building, the paint preferably containing an organic binding agent which is chemically solvable by means of a paint solving agent which is supplied on the layer of paint and which is allowed to act during a period needed for having it solved.
- the purpose of this invention is to achieve a method for removing paint which has not the drawbacks which the known methods have.
- the purpose has been achieved by means of a method in which a paint solving agent is supplied on a paint layer on a surface and is allowed to act a period until the layer has been solved.
- the method is characterized in that a rinsing agent in one or several turns is applied on the solved paint and immediately after application together with the paint is sucked away from the surface. It has proved to be advantageous to combine the chemical treatment with a mechanical treatment of the surface since that supports the fragmentation and loosening of the paint from the surface.
- the mechanical treatment can for instance be made by scraping means, brushes or the like which are applied on the nozzle which is used for sucking up the mixture.
- Supply of the rinsing agent should, when removing certain types of paint, preferably be directed to the place of the nozzle where the paint is collected before it is sucked away.
- the choise of rinsing agent depends on the type of paint. Plastic paint usually demands for chemical agents of different types and in some cases also warm air could be used whereas water can be used for alcalic paint such as oil paint. The temperature of the water should in that case be more than 40°C.
- An after treatment agent can be applied on the surface at the same time as the solved paint layer is sucked away. Such an after treatment agent is used to remove reminders of the paint solving agent and stabilize the surface after removing the paint so that a new paint layer can be applied on the surface without being damaged by any remaining paint solving agent.
- the rinsing water is as a rule applied with a comparatively low pressure which is choosen with respect to the character of the surface i.e. so that damages do not arise on the surface and so that not to large water quantities are pressed into any opening in the surface.
- the solved paint is transported to a separation unit in which the paint solving agent together with the paint is separated from the water. Then the paint solving agent is separated and reactivated in an activator unit so that it can again be used for solving paint layers.
- This invention has the advantage that the bed, that is the surface on which the paint is supplied, is spared. Also sensitive beds as for instance bad plaster can simply be cleaned without damages. Further the method is very rapid and gives a bed which is dry, stabilized and which can immediately be used for repainting. By the invention also maximum cleanness and stability is achieved. It should be pointed out that also the outer porous structure of the surface by this method can be effectively cleaned.
- the method is very suitable for removing paint indoors. Scrawling is easily removed and also fireclassified paint when repainting corridors, stair-wells and other evacuation rooms. (The fire classification presupposes a certain maximum paint layer).
- the method makes a completely controlled and environment friendly use possible. It is further possible to reuse a reactivated paintremoving agent which makes the method economically competitive.
- FIG 10 is a surface on which a paint layer 11 is applied.
- a paint solving agent is sprayed on the print layer 11 and is allowed to act for some time.
- a nozzle 12 is moved on the surface the nozzle being provided with a fixed or movable brush for mechanical treatment of the surface.
- the nozzle 12 is by means of a hose 13 connected to a container 14 which in turn is connected to a vacuum source 15.
- the nozzle is also by means of a hose 16 connected to a rinsing agent container 17 from which a rinsing agent is transported to the nozzle in the hose 16.
- the rinsing agent container can be provided with means, not shown, for heating the rinsing agent.
- the rinsing agent is water it should have a temperature which is more than 40°C and preferably is 70-90°C.
- the rinsing agent is mixed with the solved paint reminder and the paint removal agent and is sucked away in the hose 13 to the container 14 in which it is collected.
- the mixture of the paint solving agent and rinsing agent in the container 14 can then be transported to a cleaning plant 18 from which the rinsing agent is separated and leaves via an outlet 19 and as an alternative is brought back to the rinsing agent container 17.
- the paint solving agent and the solved paint might also be transported to a separation unit 20 in which the paint removing agent is separated from the paint remainders these remainders leaving through an outlet 21 and later being taken care of in a separate plant for destruction of waste which is dangerous for the environment.
- the paint removing agent is transported to an activator unit 22 in which the removal agent is reactivated and leaves through an outlet 23 so that it can again be used for removing paint.
- the rinsing container 17 is via a hose connected to a container 24 for an after treatment agent.
- This agent is supplied to the rinsing water during the last treatment of the wall in order to give the surface a pH-value which is about 7.
