Definitions

  • the present invention relates to a squeegee for equalizing, uniformizing and / or smoothing on a support paint coatings for interior work.
  • a decorative coating for example paint or wallpaper
  • the present application proposes to facilitate and make less painful the coating work of walls and ceilings and significantly increase the yield by providing a tool whose use is simple and effective.
  • the tool is a squeegee allowing the equalization, the uniformization and / or the smoothing of paint coatings for interior work deposited on all supports.
  • the squeegee is used to equalize, standardize and / or smooth the interior paint coatings deposited using one of the rolls objects applications filed the same day.
  • the squeegee includes a handle, a rear handle attachment, a blade holder, and a flexible elastomeric blade.
  • the blade of the squeegee is made of flexible elastomer.
  • the flexible elastomer has a hardness of 30 to 90 shore A.
  • the flexible elastomer is a thermoplastic elastomer (TPE) selected from thermoplastic polyurethanes (TPE-U or PTU), elastomers styrenic thermoplastics (TPE-S or TPS), olefinic thermoplastic elastomers (TPE-O or TPO) and vulcanized thermoplastic elastomers (TPE-V or TPV).
  • the flexible elastomer is a styrene-ethylene-butylene block copolymer (SEBS), a styrene-butadiene block copolymer (SBS), a thermoplastic polyurethane, a polypropylene / ethylene-propylene-diene vulcanized rubber (vulcanized PP / EPDM) ), an ethylene-octene copolymer, a nitrile-butadiene rubber, natural or polychloroprene (Neoprene®).
  • SEBS styrene-ethylene-butylene block copolymer
  • SBS styrene-butadiene block copolymer
  • thermoplastic polyurethane a polypropylene / ethylene-propylene-diene vulcanized rubber (vulcanized PP / EPDM) ), an ethylene-octene copolymer, a nitrile-butadiene rubber, natural or
  • the blade of the squeegee is a notched blade.
  • This type of squeegee is intended to equalize and standardize a deposit of paint for interior work on any support.
  • the face of the blade in contact with the support is notched and the face of the blade which is not in contact with the support is smooth.
  • the two ends of the lower edge of the blade are slightly rounded.
  • the notches of the notched blade preferably have a height of 10 to 12 mm.
  • the notches are regular in width over the entire length of the blade, for example they have a width of 2 mm.
  • the notches have a depth of 0.1 to 1.5 mm. Preferably, they do not have the same depth over the entire length of the blade. More particularly, the notches have a depth of 0.3 mm at the two rounded ends of the blade and 0.7 mm on the rest of the blade.
  • the flexible elastomer of the notched blade preferably has a hardness of 50 to 90 shore A.
  • the blade of the squeegee is a smooth blade.
  • This type of squeegee is intended to smooth a deposit of paint coating for interior work on any support.
  • the smooth-blade squeegee is used for smoothing a paint coating for interior work previously equalized with a serrated blade squeegee according to the first embodiment of the invention.
  • the two faces of the blade are smooth.
  • the two ends of the lower edge of the blade are slightly rounded.
  • the flexible elastomer of the smooth blade preferably has a hardness of 30 to 70 shore A.
  • the blade of the squeegee according to the invention has a length of 100 to 650 mm, more particularly of 250 to 500 mm.
  • the notched blade has a length of 250 or 350 mm and the smooth blade has a length of 250, 350 or 500 mm.
  • the total height of the blade is preferably between 20 and 30 mm, the protruding portion of the blade support being preferably between 15 and 20 mm.
  • the handle and the rear attachment piece of the squeegee handle are made of thermoplastic material, for example polypropylene.
  • the handle of the squeegee allows ergonomic handling and can be adapted to a suitable telescopic pole.
  • the blade support is made of thermoplastic material, for example polyvinyl chloride. It supports the flexible blade and ensures the rigidity and straightness of the blade. It can receive different types of blade.
  • the blade support has at both ends a profile endpiece.
  • the end pieces of profiles are made of thermoplastic material, for example in polypropylene.
  • Profile end caps are finishing pieces that prevent the penetration of the coating into the blade support.
  • the parts of the squeegee of the invention are made of synthetic material.
  • the squeegee is not sensitive to water and does not deform unlike traditional tools mainly composed of metal and wood.
  • the squeegee of the invention is used to even, uniform and / or smooth paint coatings for interior work.
  • interior paint coatings may be plaster for tempering with water, ready-to-use paste coatings or multi-component coatings.
  • the powder coatings are for example based on plaster, cement or organic binder.
  • the paste coatings are preferably based on organic binder.
  • the scrapers according to the invention are used to equalize, standardize and / or smooth paint coatings for interior work having a density greater than or equal to 0.5, a particle size of less than or equal to 2000 ⁇ and a viscosity of between 80,000 and 500,000 mPa.s (the viscosity is measured using a Brookfield RVDV III viscometer - Helipath S96 / 50 mm - 10 rpm at a temperature of 20 ⁇ 1 ° C).
  • toothed blade scrapers are used with interior paint coatings having a particle size less than or equal to 2000 ⁇ m and smooth blade scrapers are used with interior paint coatings having a particle size less than or equal to 1000 ⁇ .
  • Squeegees according to the invention are recommended for small and medium surface work. They are light and very manageable, they thus allow an equalization, a standardization and / or a smoothing of the paint coats for interior works with a better yield than with traditional tools, requiring less efforts with a higher smoothing power and by avoiding the majority of the defects of coating, such as overthicknesses, ribs, sardines and pullouts. The time spent to eliminate any localized defects by sanding is therefore also significantly reduced.
  • the scrapers are ready for use, the blade can be easily replaced by a new blade or by a blade of another type, for example one can replace a serrated blade with a smooth blade or vice versa.
