An improved process for creating a countertop having an imitation veined or marbleized surface including the steps of establishing a horizontally positioned mold which is constructed from an upwardly facing mold surface which is bounded by a plurality of sides to create a negative cavity enclosure. A first plurality of elongated and discrete strips of a densified polyester/acrylic resin are applied onto the upwardly directed mold face either by a polypropylene squeeze bottle or through a trigger actuated air gun as an atomized mixture of fluid resin and pressurized air. The first plurality of strips of resin material are distributed across the face of the mold according to a desired pattern and are allowed to set for a period of time, following which at least one second continuous coat of a resin material is applied over the first plurality of discrete strips according to a desired thickness of up to one-half an inch. A third continuous coat of a backer resin may be applied over the second continuous coat and the first plurality of strips and second continuous coat are each selected from a desired color to arrive at an appealing veined or marbleized contrast. A recipe of the resin material may further be augmented with a percentage additional of a silacious material to increase hardness.
Cette invention concerne un procédé amélioré de fabrication de dessus de comptoir marbrés qui comprend les étapes suivantes : mise en place d'un moule horizontal composé d'un fond délimité par une série de parois verticales formant une empreinte en creux; application sur le fond du moule d'une première série de cordons espacés de résine polyester/acrylique densifié, à partir d'un flacon pressable ou au moyen d'un pistolet pneumatique sous forme d'un mélange de résine liquide pulvérisé et d'air comprimé, lesdits cordons étant répartis selon le motif souhaité; durcissement des cordons pendant une durée déterminée; application sur les cordons susmentionnés d'au moins une deuxième couche continue de résine ayant un maximum d'un demi-pouce d'épaisseur et application, au choix, d'une troisième couche de résine sur les couches précédentes dont les couleurs sont choisies de manière à réaliser le motif marbré recherché. La matière première utilisée peut aussi être additionnée d'une certaine quantité de matière siliceuse pour en accroître la dureté.
