Ramuc® PSL is a highly versatile nitrile rubber caulking material specifically engineered for use in demanding pool environments. It is particularly well-suited for sealing expansion joints around the perimeter of pools, where it accommodates the natural movement of pool structures due to temperature changes and water pressure, providing a durable, watertight seal.

Additionally, Ramuc PSL is an excellent choice for repairing cracks that may develop over time in pool walls, steps, and other vertical or sloped surfaces. Its unique formulation allows it to be applied directly into cracks up to ½” wide, even under wet conditions, without sagging, ensuring the integrity of the repair. This material is also effective for sealing grout lines in tiled pools, particularly in areas prone to water intrusion or where traditional grouts may fail.
