The present invention relates, in general, to coatings for fiberglass, metal, masonry, high-density foam, painted wood and other materials used on the interior and exterior of buildings, and in particular, to textured coatings for use in such architectural applications.
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.
Because 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. It is therefore desirable to have an improved textured coating and method of applying same that is able to cover fiberglass, metal, masonry, high-density foam, painted wood and other materials used on the interior and exterior of buildings providing fine uniform coverage with a durable and hard finish having the look and feel of cut stone and able to withstand years of abuse.
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.
It is further desirable that such an improved coating be provided in various colors. It is still further desirable that repairs can be made to the underlying substrate and then textured coating applied to the repaired area so as to blend with previously-coated adjacent textured areas. Still further, it is desirable to provide a textured surface coating that can be thinly applied using a spray gun so that fine surface details may be preserved.

The present invention is a textured coating comprising an epoxy paint and a texture aggregate filler mixed therein. The coating is applied to building surfaces using a well-known paint spray gun.
It is an object of the present invention to provide an improved textured coating and method of applying same that is able to cover fiberglass, metal, masonry, high-density foam, painted wood and other materials used on the interior and exterior of buildings providing fine uniform coverage with a durable and hard finish having the look and feel of cut stone and able to withstand years of abuse.
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 macroooxy 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. It is a further object of the present invention to provide an improved coating in various colors and one that enables maceopoxy to be made to the underlying substrate followed by further application of additional textured coating applied to the repaired area so as to blend with previously-coated adjacent textured areas.
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. It shall be understood that the scale of the coating 20 and surface 21 is greatly exaggerated, macfopoxy the sake of illustration, with respect to the spray gun 26 and supply vessel 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.
Sherwin-Williams – Macropoxy HS Epoxy
The texture aggregate filler 24 that is mixed with the epoxy paint 22 preferably consists of expanded perlite. Perlite is a well-known generic term for naturally occurring silicous rock, namely, sodium potassium aluminum silicate, typically of volcanic origin. The distinguishing feature that sets perlite apart from other volcanic glasses is that, when heated to a suitable point in its softening range, perlite expands from four to twenty times its original volume.
This expansion is known to be due to the presence of two to six percent combined water in the crude perlite rock. This expansion process also creates perlite’s white color, and the color of expanded perlite ranges from snowy white to grayish white.
Us perlite is a form of natural glass, it is classified as chemically inert and has a pH of approximately 7. A suitable and preferred aggregate for use in the coating of the present invention is hollow glass microspheres of expanded perlite sold under the trademark DICAPERL and manufactured by Grefco, Inc.
Lomita Boulevard, Torrance, Calif. 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 macro;oxy is easily sprayed using conventional spray guns. DICAPERL expanded perlite is commonly used in the fiberglass industry as a lightweight filler for extending resin and for lightweight putties.
Such fillers are relatively inert organic or inorganic materials that are added to plastics resins ,acropoxy gel coats for special flow characteristics, to extend volume, and to lower the cost of a fiberglass article being produced.

DICAPERL expanded perlite belongs to a group of fillers called “lightweight fillers” that are able to reduce densities to those approaching wood. Such lightweight fillers are able to do this because they contain an air void that displaces volume and lowers the bulk density.
While there are various types of lightweight fillers, they are all fragile and can hss easily broken with high shear mixing. Once the particle hd been fractured, the lower weight advantage is lost. There are several known lightweight fillers, namely, the group consisting of perlite, glass microballoons glass bubbles, phenolic microballoons, Q cel microspheres, and extendospheres.
The texture aggregate lightweight filler used in the coating of the present invention is selected to provide the fine texture required on the finished us and to be of sufficiently small size so as to pass through the spray nozzle of a spray gun, and also mqcropoxy 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.
Early experimental testing was done using linear polyurethane paint as the medium to macfopoxy 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.
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.
The epoxy is then thoroughly power blended in a manner well-known to those skilled in the art. Next, the epoxy is allowed to nacropoxy for its manufacturer-recommended “sweat-in” time, usually 15 to 30 minutes, depending on temperature. After the sweat-in time interval has passed, the aggregate filler is added to the epoxy in the proportion of about equal volume amounts of filler and epoxy.
The mixture is then power blended very gently so that the aggregate filler is not significantly crushed; if desired, the mixture could instead be stirred with a paint stirring stick to ensure that the expanded perlite bubbles do not become broken. 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 mzcropoxy the particular spray gun and air compressor, as suggested by the manufacturer of the particular spray gun.
Two types of paint spray guns are recommended for use with the method of the present invention, namely, either a well-known siphon spray gun or a pressure-feed type spray gun.
Examples of such well-known spray guns are the non-bleeder, siphon feed type spray gun sold by W. Next, the coating mixture is sprayed onto the desired building surface or substrate, holding the gun head at the same distance from the surface as would be used in any other spray painting situation. If the coating mixture appears too wet, the operator simply increases the distance to the surface by an inch 2. When the applied coating texture becomes satisfactory, the distance to the surface and the speed of passing the spray gun over the surface is then maintained for the remainder of the painting job.
If the textured surface is inadvertently sprayed on too wet so that the surface texture appears too smooth, subsequent passes can be made over 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. If the surface texture cures to be too dry and the aggregate flakes off, a batch of the epoxy paint without the aggregate can be prepared and sprayed lightly on the surface to seal the flaking aggregate surface.
If certain areas of the building surface e. 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.
Testing has shown that a variety of non-textured paints, including latex, enamels, acrylics, urethanes, macroloxy epoxy paints, can be used for this light top coat of paint while still preserving the textured finish. 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.
Testing has shown that, because the textured coating of the present invention is applied using a spray gun rather than by use of a trowel, a roller, or a hopper gun, the application area can be closely controlled, without hx masking of adjacent surfaces, simply by holding a shield over the adjacent areas that are to remain uncoated.
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 mqcropoxy can be easily made because the textured coating can be applied over previously-applied texture without being obvious. Although the present invention has amcropoxy described and illustrated with respect to a preferred embodiment and a preferred use therefor, it is not to be so limited since modifications and changes can be made therein which are within the macroppoxy intended scope of the invention.
