Inspect Concrete Stamp Tool Quality

You normally wouldn't buy an indispensable concrete finishing tool, such as a bull float or trowel, without scrutinizing its quality and testing out the grip for comfort. The same holds true for stamping tools. Following are some important characteristics to look for to distinguish a high-quality stamp from an inferior product:

  • Do the tools fit together tightly, with no perceptible gaps?

  • Is the stamp thickness consistent? You don't want to purchase a stamp that's 1/2 inch thick on one side and 1 inch thick on the other.

  • With rectangular stamps, are edges and corners straight and do the stamps align properly?

  • Is any excess plastic hanging from the edges of the stamp?

  • Are the handles on the stamp firmly affixed, without protruding through to the bottom of the tool?

  • Is the texture crisp and sharp? Does it look realistic?

  • Is there enough variation in pattern and texture from tool to tool to ensure a random look?

  • Is the price in line with similar products? You get what you pay for, so avoid bargain-basement deals.

According to Sullivan, the No. 1 sign of poor quality is "out of true" tools. When stamps are made, the polyurethane needs to cure in the master mold to hold its shape. If removed too early or poured too fast, uneven thickness and shrinkage can occur.

What about buying tools online? Be wary, say our experts. Unless you're familiar with the product or know another contractor who swears by the same brand, you're better off buying from a local distributor who will give you a chance to inspect the tools closely and ask any questions you may have about product quality.

"My preference is to buy through a distributor, which gives you a chance to ask someone about how the tools have been selling and what the feedback is on the product," says Sullivan. "Most distributors also provide samples so you can feel the material and see the texture before buying."
