These large and detailed mats were created from carefully chosen reclaimed planking from Chicago’s Navy Pier. Very detailed planks with rustic grain, knots, and genuine artifacts. These will reproduce that century old look into concrete or overlay. The planks are each 14″ wide and vary in length ranging from 8 ft to 4 ft. Walttools Centennial Plank will produce the most attractive wood finish in concrete that can be found. Perfect stamp for indoor and outdoor spaces – patios, stairs, kitchens, outdoor kitchens, sidewalks, walkways, driveways, pool decks and surrounds, etc. Great pattern for anywhere you want a picturesque lumber look. Unlike other manufacturers, each plank mat is from a different board ensuring your job will have a great variety in character and detail. The varying plank lengths are also an advantage to others, more limited range. Like all stamps from Walttools, you can expect a professional grade tool with excellent fit and the heaviest straps used in the industry. Set includes: 8 rigid stamps, 1 floppy stamp (4 ft), and 1 touch-up grain skin. Also available in singles – Just check our Amazon brand store! All concrete stamps will require the use of a release agent, either liquid or powder, to prevent them from sticking to the concrete.
