|CUTTING & FABRICATING
Basic construction of building shells is usually of a rigid material such as Acrylic, Styrene, Foamboard or plywood. PLASTRUCT Plastic Patterned Sheets can then be applied to create realistic simulated finishes.
These plastic sheets are easily cut with a hobby knife or scissors. For sheet application to a substrate surface, a general purpose spray adhesive or our GES-2 Silicone Adhesive is recommended. In some cases, our PLASTRUCT Plastic Weld or Bondene Cements are preferable, however, caution must be taken to ensure proper application; too much solvent cement may melt the plastic sheet. To remove solvent stains from Styrene sheets, use a Pink Pearl eraser or fine steel wool.
When surfaces larger than a single sheet are to be covered, in most cases, the patterns are designed to allow easy and undetected joining of multiple sheets.
FINISHING & PAINTING
When working with plastics, it is sometimes necessary to fill holes, cracks or joints. For small holes or cracks, any spot putty will work nicely. For larger holes or to create stucco or mortar, we recommend using Spackle or a suitable replacement.
Plastic Patterned Sheet materials representing brick, block, stone, etc. are usually furnished in a color suitable to common applications or effects. To get realistic mortar effects for joints, use a medium to dark concrete gray color flat finish paint of alkyd oil, latex or acrylic base. We recommend Delta or Tamiya (do not use lacquers). Using tissue or a paper towel, wipe the paint into the grooves with a circular motion. With a clean tissue, wipe the excess from the surface while the paint is still wet. If multiple wipings are necessary, take care to not remove paint from the grooves. A slight paint film should be left to soften the shinny surface of the Plastic Patterned Sheet. However, if you want to remove this film it is easily accomplished using steel wool or 220 grit garnet paper.
For variegated brick, paving or stone, the above procedure followed by individual brick or rock application of varied tones of the original color provide realistic results. Further texturing may be achieved by lightly spraying a similar color over the length of the sheet approximately 20 inches above the surface. This spray procedure is also quite effective on roof shingles and on plain surfaces where an aggregate look is desired.
Plastic Patterned Sheets in clear square tile are designed for ceramic tile. It is recommended these be painted on the reverse side to keep the high gloss appearance. If speckling is desired, first spray a light mist approximately 20 inches above the sheet. Or, another way to accomplish this is to dip a toothbrush into the desired speckling paint and then, holding the toothbrush approximately 20 inches above the sheet, run your thumb over the surface of the brush. Note, you should leave most of the surface unpainted. Allow to dry, then apply the main color either with a brush or spray. Fill the tile grooves with "grout" by wiping a suitable colored paint over the top surface of the sheet as described above. Or, you may simply draw in the "grouting" with a permanent waterproof marker.
When applying a wash color over the sheet, a No. 10 or larger camel hair brush is recommended. When painting individual bricks, use a No. 0 square tip brush. Individual stones should be painted with a No. 4 brush.
We have found that many of our Plastic Patterned Sheets can be used for hard-to-find or unusual applications. For your assistance, we provide a few below:
The reverse side of our PS-13, 16 and 19 can be used for large wood planking.
PS-25, 26 and 27 make excellent road and highway guardrails when cut into strips and mounted on square posts.
PSC-40 through 46 make great glass blocks for glass block walls.
PS-47 through 59 make excellent industrial vents when modified by adding Styrene Strips to every other slat. They can also be used as window awnings.
PS-145 works nicely as frosted glass for bathroom windows or shower stall glass.
PS-23 is another excellent method for shower stall glass.
