About This Product

Price Paint Rubber Hairline Crack Filler is an advanced, flexible crack-sealing compound designed to fill and permanently seal hairline cracks in plaster, concrete, masonry and painted surfaces. Unlike rigid fillers that crack again with substrate movement, this rubber-based formulation remains flexible, expanding and contracting with the building to maintain a sealed, crack-free finish.

This product is essential preparation before painting or waterproofing, ensuring that surface cracks do not telegraph through to the final coating. Its paintable formula allows for seamless integration with topcoats, delivering a smooth, professional result. It can be applied by brush or roller and does not require specialised tools or skills.

Key Features

  • Flexible rubber crack filler
