Concrete & Mortar - Limestone/ Travertine

Removing Cement Stains from Outdoor Limestone and Travertine Surfaces

Limestone is a popular choice for patios, paths, and driveways because of its natural look and strength. During construction or renovation, cement stains can appear, leaving a hard, ugly residue. Removing these stains needs care because harsh acids can permanently damage the stone.

How Cement Stains Happen

Cement stains usually occur from:

• Messy work—spills of mortar, grout, or cement during building or paving.
• Foot traffic—workers’ shoes carrying wet mortar or cement dust onto limestone.
• Accidental spills—drips from grouting, jointing, or repointing nearby.

Once cement hardens, it becomes tough to remove without the right cleaner made for limestone.

Why Harsh Acids Hurt Limestone

Many think strong acid cleaners work best on cement stains, but acids harm limestone. This calcium-based stone reacts badly to acids, causing:

❌ Etching—acid corrodes and dulls the surface.
❌ Discolouration—acids change the stone’s natural colour.
❌ Surface damage—repeated acid use weakens limestone and lowers its durability.

Safe and Effective Cement Stain Removal

Use a specialist cleaner made for natural, acid-sensitive stone to remove cement stains safely. This cleaner:

✔ Breaks down cement residues without harming limestone.
✔ Contains no harsh acids that damage surfaces.
✔ Protects the stone’s natural look and strength.

Test Before Full Cleaning

Limestone varies in porosity, so always test a small area first. This helps you:

✅ Check if the cleaner works without damage.
✅ Estimate how much product you will need.
✅ Decide how long to leave the cleaner on the stain.
