Abstract

This comprises a long V-section or bihedral-angle-shaped body and leg pieces and which may be made of flexible steel; the leg pieces are at the end of the body and may be bent so as to adjust the height of said form or guide when supported by the legs on a surface to be stuccoed, etc. In use, the guide or forms are positioned on the surface to be coated, eg. wall or ground, then, adjusted to the same level by using a reference line and fixed to the surface. A coating of cement, etc. is applied to the surface and a scraper or sleeker is run over the outer edge of the guide or form to scrape the cement into a flat and even surface. <IMAGE>

Description

SPECIFICATION Form for use in applying plaster and the like This invention relates to a device for facilitating the production of level coatings of cement, plaster, stucco and the like on surfaces such as floors and walls.

Generally, in the process of building, for example a house, the floor, walls and any columns etc. are finished with two coats of cement or plaster, the first coarse and the second fine. Afterwards follows decoration such as pointing, applying wallpaper, laying tiles, glazed brick or washed sand stone. The second layer of cement, plaster or stucco is most important and considerable workmanship is involved. If done by inferior workmanship, the final finish of the wall or floor is not evenly flat, leading to problems in decorating walls and possibly giving rise to puddles in floors. The present invention makes it possible for a good, even and smooth finish to cement, plaster or stucco work to be produced even by a relatively unskilled apprentice.

According to the present invention, a guide or form for facilitating the production of a flat surface in cement, plaster or stucco work comprises a straight elongate member of V-shaped section having at or near each end a pair of legs each leg of a pair extending from an edge of the V-section and being of flexible metal so that it may be bent to adjust the position of the elongate member above a surface with which the legs are in contact.

Using two or more such guides or forms set up on a surface such as a floor or on a wall, to be finished with a coating of cement, plaster of stucco, then the coating may be smoothed by a scraper or a sleeker laid across the upper edges of the guides or forms.

This can be done by an ordinary apprentice to obtain a fine result.

This invention is illustrated by the accompanying drawings in which: Figure 1 shows a perspective view of an embodiment of this invention.

Figure 2 shows an embodiment of this invention being used on a floor cement stucco.

Figure 3 shows (in section) this invention being used for column stucco work.

Figure 1 shows a device of this invention, which comprises a long V-section or bihedral-angle shaped body (1), and two leg pieces (2) extending outwardly at each end of the body (1). All the aforesaid components may be made of flexible steel. The said leg pieces (2) may be closed or opened or otherwise bent for adjusting the height of the body (1). When using this invention, the leg pieces (2) are fixedly attached to the floor or wall surface to be coated but before attaching said leg piece (2), a reference line is set up with a levelling instrument for locating all said bodies (1) in the same plane. In the case of a floor surface which initially is not evently flat, a common flat level may be obtained by adjusting the leg pieces (2) by closing or opening them so that when the devices are located on the floor all the bodies are on the same level.The leg pieces (2) are then fixed on the surface to be finished with cement or other suitable adhesives. Preferably, the end portions of the legs are bent so as to lie on the surface and so facilitate fixing thereto by adhesion.

Since the size of working area varies from place to place, the devices of this invention are manufactured in an appropriate range of length to facilitate the user fixing them at distances appropriate to the size of a working area. When determining the distances between the devices, consideration should be given to the feature of the scraper or sleeker to be used.

When the devices have been set up on the same level, the cement is poured in slight excess over the working area, and a scraper is used to scrape along the outer edge of the body (1), where upon an evenly flat cement surface is obtained, the slight excess being removed.

Figure 2 shows an embodiment of this invention being used on a floor cement stucco. In Figure 2 (3) indicates the basic floor and (4) indicates the cement stucco layer which isto be finished.

When using this invention to finish a wall, the working procedures are the same as that of finishing a floor surface. First, the body (1) of stucco forms are aligned in the same plane on the wall by means of a plumb line, the leg pieces (2) being appropriately adjusted; then, leg pieces (2) are fixed to the wall with adhesive and a sleeker or scraper is used to smooth the coating of cement or plaster applied.

Again, when finishing a wall using this invention, the distance between each device should be matched with the scraper or the sleeker to be used to level the coating.

Figure 3 shows this invention being used for column stucco work; since the working area on the column (5) is rather small, the devices are fixed over the corners of the column by attaching the leg pieces (2) to the two sides of each corner after being appropriately adjusted using a plumb line to set a reference line for aligning all the bodies (1) to the same level. A scraper is then used to scrape the coating of cement (4) from the upper portion of the applied coating downwards for a smooth surface.

1. A guide or form for facilitating the production of a flat surface in cement, plaster or stucco work comprises a straight elongate member of V-shaped section having at or near each end a pair of legs each leg of a pair extending from an edge of the V-section and being of flexible metal so that it may be bent to adjust the position of the elongate member above a surface with which the legs are in contact.

2. A guide or form as claimed in Claim 1 made of flexible steel.

3. A method of applying a coating of cement, plaster stucco or the like to surfaces in which a multiplicity of guides orforms as claimed in Claim 1 or 2 are aligned and fixed at spaced points on the surface, a coating of cement, plaster, stucco or the like being applied to the surface to a depth at least
