Scofield
introduces
By Robert Harris and Bruce Hackett
While
much has been written about the use of self-leveling overlayments for
interior commercial applications such as casinos, malls, hotels, and office
building lobbies, these self-leveling materials will not accept imprinting,
stenciling or texturing, nor are they appropriate for exterior installations.
Both types of Scofield Texturetop have numerous benefits compared to other topping materials, including high strength, excellent resistance to moisture and freezing/thawing, and an appealing range of standard and custom decorative colors. Scofield Texturetop is easy to mix and economical to install. Contractors simply add the bagged mix to pre-measured water, mix and place, according to manufacturer specifications. Either type of Scofield Texturetop provides fast setting and rapid strength gain, which permits fasttrack installations, an important concern for many customers. Scofield Texturetop Stencil Grade is designed for applications where various Texturetop Stencil Grade is applied with a broom, squeegee, trowel, sprayer or air-driven hopper gun over the top of a paper stencil and allowed t o stiffen for several hours. Upon removal of the stencil, the result is an attractive, decorative pattern made from the durable, cementitious topping. Scofield Texturetop Stamp Grade can be imprinted by the use of LithotexÔ PavecraftersÒ a system of mat-type imprinting tools and thin, flexible embossing skins. Scofield Texturetop Stamp Grade is installed at a thickness two times as deep as the deepest profile of the embossing skin or imprinting tool being used, which ensures a layer of paste between the texturing tool and the concrete substrate. Because timing is crucial to successful imprinting, the Texturetop mortar should be allowed to stiffen until it is sufficiently rigid to support stamping operations, yet remain plastic enough to imprint properly. Absolutely
essential to the successful installation of Scofield Just as with any cementitious product installed outdoors, weather plays an important role when installing either type of Scofield Texturetop in exterior applications. Ambient and substrate temperatures must be in acceptable ranges, and wind and rain must be minimal or absent. For any kind of Scofield Texturetop installation, Scofield recommends the use of tools and equipment marketed by Wagman Tools. The mixing buckets, gauge rakes, smoothers and hand trowels offered by Wagman have proven track records in numerous successful installations of Scofield Texturetop. Following
installation, Texturetop surfaces can be chemically stained with Lithochrome®
Chemstain® if desired, which reacts with the surface of cured Texturetop
toppings to produce permanent, translucent, variegated color effects.
All Texturetop surfaces should be sealed or coated in order to protect
the surface and make periodic maintenance easier. Scofield offers a range
of products that provide the necessary surface protection and improve
appearance: Scofield™ Cureseal™, Cementone™ Clear Sealer,
The Scofield™ Clearcoat™ system, or, in instances where additional
color is desired, Colorcure™ Concrete Sealer. |
