LIMESTONE is a favourite in UK homes, often found in kitchens, hallways, and open-plan spaces. It brings a natural warmth and quiet elegance that never goes out of style. But because it’s a calcium-based stone, it does need a bit of extra care. Being soft and porous, it can mark, etch, or wear down if it’s left unprotected.

Whether you’re laying a brand-new floor or looking after one that’s been in place for years, the goal is the same: treat it like a living surface, and it will reward you as it ages. For installers, knowing how to care for it properly isn’t just about preserving the stone; it’s also about keeping clients happy and building the kind of trust that brings repeat work.

Seal it from the start
Says Fila: ‘Most damage happens when limestone is left unsealed. A breathable, water- and oil-repellent treatment such as FILA’s MP90 ECO XTREME helps guard against everyday spills, from muddy boots to kitchen splashes.

‘This water-based sealer has an extremely low VOC content, a low environmental impact, and carries Indoor Air Comfort Gold certification. Because it leaves no surface film, the stone’s natural look stays intact while the protection works in the background.’

Stay on top of cleaning
Continues the company: ‘Once it’s sealed, limestone is easy to live with. The main thing to avoid is using strong, chemical-heavy cleaners, as these can wear down the surface. A pH-neutral option like CLEANER PRO is a much safer choice, gentle enough for polished stone, but still more than capable of lifting everyday dirt.

‘Most of the time, a light dilution will keep things looking fresh. In high-traffic spots like hallways, you can go a little stronger to tackle heavier soil without causing any harm. Whether you’re mopping by hand or using a floor machine, it’s a simple, streak-free clean that keeps the stone looking its best.’

Know when to deep clean
Adds the company: ‘Even with good care, limestone can lose its brightness. Grime builds up, or the wrong cleaner leaves residue. That’s when a deep clean can make all the difference.

‘PS87 PRO is a professional-grade degreaser and post construction cleaner for stone that lifts grease and surface buildup without being too aggressive on acid-sensitive materials. Often used after renovation work, it’s just as useful for giving older floors a reset. The process is straightforward: apply the diluted solution, brush the surface, collect the residues, and rinse thoroughly.’

For the long haul
Limestone’s charm comes from the fact that it’s a natural, living material. With breathable protection, the right cleaner, and the occasional deep clean, it can stay beautiful for decades.

For installers, leaving clients with a simple aftercare plan builds trust and protects the investment. It’s a small step that delivers long-lasting results while supporting a sustainable approach to natural stone care.
