Overall Good Product
I was looking for faux stone in 4x8 panels and found FauxStoneSheets to be the best priced and best looking. Nearly all other suppliers sell far smaller 2x4 panels, which create undesirable pattern repetition.
These panels are made from a vacuum-formed, thin, plastic shell of the rock/stone pattern mold, then filled with expanding polyurethane foam, resulting in a light, rigid panel for it's size. Easy for one person to pick up and carry with two hands.
The plastic shell is then painted to create the hues and tones depicted on the website for the different named variations. The variation in hues and tones of the actual product received were much more muted and less saturated compared to the images on the website, but not enough to return or not use as intended (to create an interior accent wall).
Re. the pattern for those that need to know, all four 4x8 panels are identical. However, when installed in a 2x2 array, the repetition is scantly seen. You would need at least a 4x4 array or larger to see repetition.
Gotta say, freight shipping was HORRENDOUS! Almost as much as the four panels I purchased themselves.
Re. Product Quality, the vacu-formed shell did have several areas on the edges/lips where the plastic had cracked on a sharp corner, became unadhered from the foam, or was chipped along the edge from being a little too brittle and thin, but for the most part, the shells were thick enough to be sturdy and blemish-free. As for the finish of the foam filling, it was much more non-uniform in texture and finish, with visible swirls and pour marks that made the surface somewhat uneven and "lumpy." A few foam blob drips from pouring or splattering from an adjacent mold went unnoticed UNTIL after the construction adhesive had cured, causing the panels to not fully seat against wood frames (think studio set flats). So, BE SURE TO INSPECT your panels and remove such blemishes and protrusions before adhering to your structure!
Lastly, the underlap ledges around the panel perimeters, where one "joins/overlaps" one panel with another, create a deeper "grout" line between the stones than the grout lines of the molded pattern. This causes the seam to be slightly darker, due to a deeper shadow, than the rest of the panel's grout. The darkness can be somewhat reduced by "squeezing" the panels closer together, but if too much, then the seam becomes just as visible, due to the "grout" line being narrower than the molded pattern grout lines.
