Lime vs Pitch Marking Paint

The short answer

Purpose-made pitch marking paint is safer for players, kinder to the grass and gives brighter, longer-lasting lines than lime. Hydrated lime is caustic and can burn skin and eyes. Water-based line marking paint does the same job without that risk.

Lime vs paint at a glance

Lime Pitch marking paint
Player safety Hydrated lime is caustic and can burn skin and eyes Water-based, made for sports pitches
Grass Can scorch the grass along the line Formulated for natural grass
Line quality Powdery, uneven edges Crisp, bright, even lines
In the rain Washes out quickly Weather-resistant once dry
Handling Dusty to mix and pour, needs gloves and eye protection Mix with water, or ready to use with no mixing
Machines Wheel-to-wheel lime markers Transfer wheel, spray and robotic markers

Why lime is a risk

Hydrated lime (calcium hydroxide) is strongly alkaline. Wet lime on skin, or dust in the eyes, can cause chemical burns. Players sliding, diving or lying on fresh lines are the most exposed, and children are especially at risk.

Education and sports bodies in several countries now list hydrated lime as unsuitable for marking sports fields and recommend purpose-made, water-based products instead.

Why clubs switch to paint

Safer for playersNo caustic powder on the pitch, in the kit or in the changing room.
Brighter, longer linesSharp white lines that hold up through matches, training and rain.
Quicker markingLess mixing, less mess and fewer re-marks between games.
“In the past used lime but switched to pitch marking paint. It is easier to use and produces great white lines.”Donal M, verified customer, GAA club

Lime vs paint FAQs

Is lime safe for marking pitches?

Hydrated lime is caustic and can cause skin and eye burns, especially when wet. Purpose-made, water-based pitch marking paint is the safer choice for players.

Can I use my old lime marker with paint?

Lime wheel markers are not designed for liquid paint. A transfer wheel marker like the Pitchmark Classic works in a similar way and is built for paint.

Does pitch marking paint kill grass?

Pitchmark paints are made for natural grass. Household emulsion and lime can scorch or smother the grass, which is why purpose-made paint is recommended.

Is paint more expensive than lime?

A 10L concentrate marks around 4 to 6 full-size pitches depending on the paint. Lines last longer, so most clubs re-mark less often.

Which paint is best for a GAA pitch?

Most GAA clubs marking weekly use Clubline White. For brighter, longer-lasting lines choose Lumen or Extreme. See our GAA paint guide.
