JPS6057914B2 - Roller application method for multi-colored paint - Google Patents

Description

DETAILED DESCRIPTION OF THE INVENTION The present invention is a method for applying a multi-colored paint by roller coating.

Multicolored pattern paints are widely used for painting the interior and exterior walls of buildings because the coating film not only has a multicolored pattern finish, but also a three-dimensional pattern finish to some extent.

To apply this multi-colored paint, the nozzle diameter of the normally used spray gun is small and the paint cannot be discharged, so it is necessary to use a ``Zoracoat gun'' specifically designed for multi-colored pattern paint, or use a mortar gun. It didn't happen. On the other hand, roller painting is becoming popular in architectural painting, but the advantages of roller painting are that it requires almost no curing, whereas spraying requires extensive curing, and it is easy to work with. It is said that the coating has good properties, does not require much skill on the part of the operator, and can be easily painted on small areas. Therefore, it would be very convenient if roller painting could be used to apply multi-colored paint, but conventionally, when painting with a roller, the roller presses down on the pattern itself, making it impossible to achieve a uniform multi-colored pattern. The reality is that roller painting has not been seriously considered. Therefore, the inventor of the present invention has discovered that the intended purpose can be achieved by applying multi-colored paint using a multi-colored paint roller ゜ ゛ ▼ -fref exploratory call ← 4J, 111. .

That is, the present invention provides a roller coating method for multi-colored pattern paint, which comprises preparing the surface to be painted, applying a sealer and undercoat if necessary, and then applying the multi-colored pattern paint using a porous roller. It is related to. In the present invention, after preparing the surface of the surface to be painted, such as removing dust and dirt from the surface of a building, etc., apply an alkaline sealer if the surface to be painted is concrete, or apply an alkaline sealer if the surface is wood, as in normal painting. It is preferable to apply a wood sealer to prevent the material from affecting the top coat and to create a uniform pattern. Next, if necessary, apply an undercoat for multi-colored paint using an ordinary up roller for 10 to 30 minutes.
Paint to a dry film thickness of 30μ. Examples of paint components include synthetic resin paints and emulsion paints used for architecture and wood. The porous roller used in the present invention is a roller that is commercially available as a roller for painting aggregates.It is a sponge-like roller that uses polyurethane on the foam side and is made porous by the bubbles of the urethane foam. be. There are various types depending on the diameter of the bubbles. The undercoat paint is applied with a roller, and after drying, the multicolored pattern paint is applied with a porous roller.

If a roller other than a porous roller is used, the pattern will be uneven and the intended purpose cannot be achieved, so a porous roller is always used. Porous rollers may be the commercially available ones mentioned above, but the diameter of the bubbles makes it difficult to form patterns, so it is better to avoid rollers with too small or too large diameters. It is suitable for the pattern finishing of the present invention that there are about 5 to 5 nods. The method of using this porous roller is no different in that it uses a multi-colored paint, and any ordinary painting method may be used. There are no particular limitations on the multi-colored paint, and a wide variety of paints can be used, including water-based multi-colored paints that have been developed recently. The first feature of the present invention is that roller coating can provide the same multicolored pattern as spray coating.

This is due to the use of a porous roller in the coating tool, which allows the roller to avoid slipping on the painted surface, allowing for a uniform finish with a multicolored pattern. Secondly, since multi-colored paint can be applied with a roller, it eliminates curing problems associated with spraying work, improves work efficiency, and greatly contributes to streamlining the use of paint. The present invention will be explained below using examples.

Example 1 After removing dust, oil, etc. from the concrete surface and thoroughly drying the base surface, a commercially available alkaline sealer is applied.

Next, SD Horus White (manufactured by Kansai Paint Co., Ltd., product name)
Apply a synthetic resin blended paint to a dry film thickness of approximately 20μ using a Nappu roller. After leaving the coating for a day and night, use a porous roller (manufactured by Yoshikawa Brush Co., Ltd., material polyurethane, number of holes 8/inch) to apply Zola Coat (trade name, Kansai Paint Co., Ltd., multicolored paint). Paint with a roller. The base surface was horizontal. The roller did not slip and formed a uniform multicolored pattern, which was comparable to that painted with a Zola coat gun. Example 2 After removing dust, oil, etc. from the concrete surface and thoroughly drying the base surface, a commercially available alkaline sealer is applied.
