The Spa/Bucket Board with Spikes is designed for use in pool and spa construction. This board keeps buckets elevated and stable while finishes such as concrete, tile, or plaster are being applied. The underside of this 12” x 12” aluminum plate includes four low-profile metal spikes that provide a stable grip on slick or uneven surfaces, preventing spills with minimal disruption to the finish below. Ideal for tiling, resurfacing, or detailed finish work, this board is a job site essential for precise, uninterrupted finishes.
