The key to a successful floor marking job is preparation

If we can work together to ensure the following advice is followed in advance of our arrival, we have the greatest probability of success.

Have a chat with the team at KIWI if you have old concrete surfaces and/or you have had trouble with markings staying on as we have options for removing and starting again.


Excessive Dirt

If there is excess dirt, dust, or mud across the surface, it will need to be cleaned before our arrival.

Surface Cleaning

Please do not clean concrete surfaces by hosing down prior to our arrival. In ideal conditions concrete should be dry for a few days prior to painting, otherwise as moisture evaporates from the concrete and the paint can lift. Concrete surfaces are best cleaned with a broom or scrubber. We can arrange for this should you require.

Coating + Sealants

Impact of Concrete Curing Agents and Sealants

There are a variety of concrete curing agents and sealants on the market today.

Each has a different effect on line marking paint. It is your responsibility to inform us of any chemicals that have been applied that may affect the floor marking process.

If you are not certain, don’t worry – we can organise a small test area to be marked in advance to ascertain any potential effects on coating.

New Concrete

Newly laid concrete will leach chemicals that will cause paint to lift. As such it is advisable to wait up to 6 weeks after new concrete is laid before marking.


New bitumen will leach chemicals that affect the paint, changing the colour and lifting it in some cases.

Please let us know in advance if the bitumen is to be marked shortly after being laid.


A clear site makes the process efficient and cost effective. 

Please ensure that all obstacles and hazards that may interfere with works to be carried out are removed.
If we can't finish the works and we need to come back, extra call out charges may apply.
