A textured coating and method of applying same.
Macropoxy HS Epoxy
Such lightweight fillers are able to do this because they contain an air void that displaces volume and lowers the bulk density. Can be applied to marginally prepared surfaces.
Long-term durability Corrosion resistant Resistant to many solvents and chemicals Barrier coat or universal primer when applying high performance coating over alkyds, to prevent lifting Low VOC Recommended Usage For use over prepared substrates such as steel and concrete in industrial environments. It shall be understood that the scale of the coating 20 and surface 21 is greatly exaggerated, for the sake of illustration, with respect to the spray gun 26 and supply vessel Sprayable phosphate cementitious coatings and a method and apparatus for the production thereof.
Surface 21 may be, for example, fiberglass, metal, masonry, high-density foam, painted wood and other materials used on the interior and exterior of buildings.
May be used as a one or two coat, direct-to-metal protective coating. It is a further object of the present invention to provide an improved textured coating that can be applied using a conventional spray gun so that application of the coating can be accomplished after all building panels and trim are installed, thereby permitting on-site covering of all joints, screw heads, etc.
First, the well-known high-solids polyamide epoxy paint is mixed according to the manufacturer’s specified proportion, usually one part resin base to one part hardener.
Macropoxy HS Epoxy – Protective & Marine
Groover, Fundamentals of Modern Manufacturing Required, but not published. It is a still further object of the present invention to provide a textured coating that can be thinly applied to a surface using a spray gun so that fine surface details can be preserved.
Additionally, the air pressure for the spray gun can be adjusted, in a manner well-known to those skilled in the art, to compensate for variations in viscosity and to adjust for the particular spray gun and air compressor, as suggested by the manufacturer of the particular spray gun.
The preferred size for use with the coating of the present invention is DICAPERL HP, and experimental testing has shown that this size produces a pleasing textured finish that is easily sprayed using conventional spray guns.
The texture-coated surface is then left to cure for the recommended curing time for the epoxy. US USA en Because perlite is a form of natural glass, it is classified as chemically inert and has a pH of approximately 7.
Macropoxxy of the substantial coating thickness that results when prior art textured coatings are trowelled, rolled, or “hopper gunned” onto a surface, fine surface details become hidden. There are several known lightweight fillers, namely, the group consisting of perlite, glass microballoons ns bubbles, phenolic microballoons, Q cel microspheres, and extendospheres. Finally, if another color other than the color of the epoxy paint is required for the textured surface, a light coat of paint can be sprayed over the textured surface, taking care that the coat is light enough not to fill the texture, and that about 24 hours of curing time has passed to allow the base texture coating to partially cure.
Hydraulic cement composition and method for use as protective coating macropoxg substrates. It is a further object of the present invention to provide ha improved coating in various colors and one that enables repairs to be made to the underlying substrate followed by further application of additional textured coating applied macroooxy the repaired area so as to blend with previously-coated adjacent textured areas. Barrier coat or universal primer when applying high performance coating over alkyds, to prevent lifting.
Attachments There are no attachments for this article. Such an improved coating should be able to be applied using a conventional spray gun so that application of the coating can be accomplished after all building panels and trim are installed, thereby permitting on-site covering of all joints, screw heads, etc.
The epoxy and the filler are mixed in about equal volume.
This expansion process also creates perlite’s white color, and the color of expanded perlite ranges from snowy white to grayish white. The method has the steps of: Be the first to post a comment.
Testing has shown that seams, caulked joints, floated seams, filled countersunk screw holes and other surface features can be covered by using the method of the present invention, and that repairs can be easily made because the textured coating can be applied over previously-applied texture macropxoy being obvious. The coating as recited in claim 2, in which said epoxy paint has a first volume and said filler has a second volume about equal to said first volume.
The texture aggregate filler 24 that is mixed with the epoxy paint 22 preferably consists of expanded perlite. Dicaperl HP Dec. If the textured surface is inadvertently sprayed on too wet so that the surface texture appears too smooth, subsequent passes can be made macrpoxy the surface after the coating has become partially cured, which can be determined by making occasional small spray passes over the previously-sprayed surface to see if the desired texture is maintained.
The epoxy is then thoroughly power blended in a manner well-known to those skilled in the art. A sprayable textured coating, said coating being of sufficient texture size and viscosity so as to be sprayable through a paint spray gun nozzle having an inner diameter of 1.
Because of the weight and size of aggregate, the thickness of the medium holding the aggregate, and the manner of application hopper gun, trowel, or rollerknown prior art approaches for creating and applying textured coatings have not been able to uniformly distribute the prior art textured coatings onto fine-detail multi-profile building shapes, nor have the prior art coatings and application methods been able to achieve a fine uniform coverage having the look and feel of cut stone.
System Three Resins, Inc. The texture aggregate lightweight filler used in the coating of the present invention is selected to provide the fine texture required on the finished surface and to be of sufficiently small size so as to pass through the spray nozzle of a spray gun, and also is chosen because of the lightweight nature of the filler, thereby enabling the textured epoxy mixture to be siphoned up into the spray gun head of a siphon spray gun as well as through the hoses and gun head of pressure spray paint guns.
Insulating composition comprising a foamed adhesive admixed with particulate insulating material. Early experimental testing was done using linear polyurethane paint as the medium to which the aggregate filler was added rather than high-solids polyamide epoxy being used as the medium, but the linear polyurethane paint with aggregate filler was found to be markedly inferior to the epoxy with aggregate filler, and use of the linear polyurethane paint with aggregate filler was discovered to require that another coat of linear polyurethane paint without aggregate filler be applied on top of the linear polyurethane paint with aggregate filler in order to achieve even a minimally acceptable hard surface.
Testing has shown that there is minimal overspray with the coating of the present invention when applied in the manner described, and what minimal overspray that is present exhibits the characteristics similar to “dry fall” so as to permit easy cleanup. Fontana et al, Publ. Method for thermally insulating oil and gas pipes and paint compositions for coating the inner surface of oil and gas pipes.
The coating is applied to building surfaces using a well-known paint spray gun.
