- the invention relates generally to methods and compositions for laying floor tiles.
- Laying floor tiles is a time consuming process involving numerous labor intensive steps. Firstly, a metal screen has to be laid over top of the sub floor and stapled in place. This requires cutting the screen into sections and laying the sections in end to end alignment on the sub-floor. The screens are then stapled to the sub-floor to hold them in place. After the screen is laid on the sub-floor, cement is mixed and then layered onto the metal screen. This requires the mixing of the cement mixture, the troweling of the cement into and onto the metal screen, the leveling of the cement and then the hardening and curing of the cement. In addition to being a dirty and time consuming process, the troweling of the cement requires the use of a cement mixing device.
- the hardening and curing process can take anything from one to several days depending on the relative humidity and the temperature.
- the floor cannot be walked on during the hardening/curing process, making it more difficult to apply the cement.

Abstract
The present invention is a scratch board for laying on a sub-floor to form a foundation for floor tiles. The scratch board consists of a rectangular flat board made of cement and has opposite first and second surfaces. The board has a metal screen extending throughout the board parallel between the first and second surfaces and a mesh screen extending throughout the board and imbedded in the first surface. The scratch board is used to construct a tile floor by first covering the sub-floor with a plurality of the boards and securing them to the sub-floor with a staples. A tile adhesive is then spread overtop of the boards and the tiles are then laid onto the adhesive. The boards themselves are manufactured by first placing the mesh screen and then the metal screen into a rectangular form. Wet cement is then poured into the rectangular form and then leveled to form one of the surfaces. The cement is left to cure before removing the finished board from the form.
Description
- The invention relates generally to methods and compositions for laying floor tiles.
- Laying floor tiles is a time consuming process involving numerous labor intensive steps. Firstly, a metal screen has to be laid over top of the sub floor and stapled in place. This requires cutting the screen into sections and laying the sections in end to end alignment on the sub-floor. The screens are then stapled to the sub-floor to hold them in place. After the screen is laid on the sub-floor, cement is mixed and then layered onto the metal screen. This requires the mixing of the cement mixture, the troweling of the cement into and onto the metal screen, the leveling of the cement and then the hardening and curing of the cement. In addition to being a dirty and time consuming process, the troweling of the cement requires the use of a cement mixing device. Furthermore, the hardening and curing process can take anything from one to several days depending on the relative humidity and the temperature. The floor cannot be walked on during the hardening/curing process, making it more difficult to apply the cement. Finally, after the cement if fully cured, a layer of tile adhesive can be applied to the top surface of the cement and the tiles applied.
- The laying of the cement layer is required since tiles cannot be applied directly to the sub-floor. The laying of the cement is often the rate limiting step requiring the most amount of labor and time. Therefore, a system which stream lines the laying of the cement over the sub-floor would increase the productivity of the process.
- In accordance with the present invention, there is provided a scratch board for laying on a sub-floor to form a foundation for floor tiles. The scratch board consists of a rectangular flat board made of cement and having opposite first and second surfaces. The board has a metal screen extending throughout the board parallel between the first and second surfaces and a mesh screen extending throughout the board and imbedded in the first surface.
- The invention also includes a method of manufacturing a tile floor using the scratch boards mentioned above consisting of the steps of covering the sub-floor with a plurality of boards and securing the boards to the sub-floor with a plurality of staples. A tile adhesive is then spread overtop of the boards after the boards have been secured to the sub-floor and then the tiles are laid onto the adhesive.
- The invention further includes a method of manufacturing the scratch board described above consisting of placing the mesh screen into a rectangular form and then placing the screen over top of the mesh screen in the rectangular form. Wet cement is then poured into the rectangular form containing the mesh screen and metal screen. The cement in the form is then leveled to form one of the surfaces and the cement is left to cure before removing the finished board from the form.
- With the foregoing in view, and other advantages as will become apparent to those skilled in the art to which this invention relates as this specification proceeds, the invention is herein described by reference to the accompanying drawings forming a part hereof, which includes a description of the preferred typical embodiment of the principles of the present invention.

- Referring firstly to
FIGS. 1 and 2 , a scratch board made in accordance with the present invention is shown generally asitem 10 and consists of arectangular board 12 havingopposite surfaces Board 12 is made of cement and hasfabric mesh screen 18 embedded insurface 16 andmetal screen 20 embedded incement 22.Metal screen 20 comprises a standard expanded galvanized steel screen as used to form concrete floors and the like.Metal screen 20 is located in the approximate center ofboard 12.Cement 22 consists of a cured mix of Portland cement, silica sand and a plasticizer. The plasticizer permits the board to retain a limited amount of flexibility. Many suitable plasticizers are available for use in the construction ofboard 12 including Plastifier Bu-40™ from Sika™. (or any plasticizer equivalent thereto). In the case of Plastifier Bu-40, a good finished product having suitable flexibility is created by adding sufficient plasticizer to equal approximately 2% of the weight of the cement. In addition, up to about 0.5% by weight of a water resistance additive such as Plastocrete DM™ from Sika™ (or any water resistance additive equivalent thereto) may be added to increase the water resistance of the finished product. -
Fabric mesh screen 18 is embedded intosurface 16 and acts to keep the surface contiguous and free from cracking and crumbling. In order to ensure that the fabric screen acts to keepsurface 16 contiguous,screen 18 is embedded into the cement and is integral thereto.Fabric screen 18 may comprise a polymer fabric screen having a mesh size sufficient to keepsurface 16 from crumbling. Alternatively, afabric screen 18 may consist of a loose fiber mat which is embedded in the surface. - Referring now to
FIGS. 3 and 4 , the method of manufacturing the scratch board will now be discussed. Firstly, arectangular form 26 is placed onplatform 24. Rectangular form hassides 25,bottom 27 andopen top 28.Mesh screen 29 is then placed inform 26.Mesh screen 29 is dimensioned and configured to fit flat inform 26 and completely coverbottom 27. After mesh screen is placed in the form,metal screen 30 is placed in the form.Metal screen 30 is dimensioned to fit flat inform 26 over top ofmesh screen 20 and completely coverbottom 27. - After
mesh screen 29 andmetal screen 30 are placed inform 26, the form is passed under cement hopper/dispenser 32. Hopper 32 is filled withwet cement 35 and has aspout 34 which is configured to permit a continuous ribbon ofwet cement 36 to pass through the spout. The composition ofcement 35 is selected to ensure that it is capable of flowing freely throughspout 34.Form 26 is passed under and throughcement ribbon stream 36 at a rate selected to ensure that the form is completely filled as it passes through the stream.Cement ribbon stream 36 is preferably dimensioned to be as wide asform 26 to ensure that the form can be completely filled with wet cement after passing only once through the stream.Vibrator device 40 is positioned onplatform 24 and oriented relative to hopper 32 such thatform 26 is vibrated while it is being filled with wet cement. Vibratingform 26 permits the wet cement to fill the form more completely without forming air bubbles or air pockets. - After
form 26 has been filled with wet cement,level member 38 is passed over the cement form to level the top surface of the wet cement. The cement filled form is then left to cure for at least 24 hours to 7 days. The cured cement board may then be removed from the form and allowed to cure further at room temperature. Depending on the temperature and the relative humidity, the boards will be fully cured within approximately 28 days. - Referring now to
FIGS. 5 and 6 , the method of using the scratch board of the present invention to construct a tiled floor will now be discussed. Firstly, surface 42 ofsub-floor 40 is prepared by sweeping away any large debris which may be present on the sub-floor.Surface 42 does not have to be thoroughly clean or dust free.Boards 12 are then laid on top ofsub-floor 40 in abutting end to end fashion.Boards 12 should be laid on the sub-floor withsurface 14 facing upwardly. The boards are then secured to the sub-floor by a plurality ofmetal staples 46.Metal staples 46 consist of a standard U shaped metal staple having a pair oftines 45 and across member 44.Board 12 is made sufficiently flexible by the addition of a plasticizer to permittines 45 to penetrate through the board without cracking the board.Metal screen 20 inboard 12 provides the structural support need to preventcross member 44 from penetrating completely through the board. Ifmetal screen 20 was not present in the board, or if a plastic or fabric screen was used in place ofmetal screen 20, then staple 46 would be able to pass directly throughboard 12 and the board could not be securely mounted tosub-floor 40.Staples 46 are applied using a standard staple gun. Afterboards 12 are stapled tosub-floor 40, anadhesive layer 48 is laid directly ontosurface 14 of the boards and then tiles 50 are positioned onto the adhesive layer. - It will be appreciated that covering the sub-floor with
boards 12 is a relatively simple and quick procedure. It is simple to install the boards since the workers can walk on top of the boards to install them and secure them to the sub-floor. Furthermore, as soon as the boards are installed on the sub-floor, the process of adhering the tiles to the boards can begin. Finally, sincesurface 14 ofboards 12 is quite flat, the installation of the tiles proceeds quicker since there are fewer bumps and ridges to contend with. The finished floor is also superior since the boards are not bonded to the sub-floor but are attached to it by a plurality of staples. Sinceboards 12 have a certain degree of flexibility, the boards tend to float oversub-floor 40, providing a smoother and more level finished tiled floor. - A specific embodiment of the present invention has been disclosed; however, several variations of the disclosed embodiment could be envisioned as within the scope of this invention. It is to be understood that the present invention is not limited to the embodiments described above, but encompasses any and all embodiments within the scope of the following claims.
