Small pool medallion is 29" in diameter and features beautiful and attractive mosaic images. Pool emblems are removeable, unlike pool decals that require adhesive and permanent installation. Vinyl pool art can be used as a great pool accessory without the need to drain the pool. Simply drop removable pool art into the pool and let it sink to the bottom. Made of 1/8" thick vinyl (the same material used in vinyl pool liners). Small pool mosaic images offer affordable and unique style and design to the pool. Use pool decal mats for swimming pool decorations at pool parties, corporate events, year round, and in indoor or outdoor swimming pools. Cover unsightly pool stains and rust spots rather than repainting or paying for costly cosmetic pool repairs. Affordable accessory for all types of pools including concrete pools, vinyl pools, above ground pools, inground pools, gunite and fiberglass pools. Won't interfere with automatic pool cleaners and resists pool chemicals and UV rays. Poolmats recommends that you don't place pool mosaic emblems on an incline or rough surface as air bubbles underneath the material will cause pool art to shift.
