Line & Surface Marking FAQ's

We've put together some commonly asked questions to give you more information about Meon's products and services.

If you have a question that you can't find the answer to, please use the contact page to get in touch.

What is the minimum temperature I can lay product at?

Refer to TDS, as it varies across products. Typically 5°C for solvent-based & 10°C for water-based and solvent-free products.


Check products TDS. Normal value is a maximum of 7% moisture content in the surface. This can be measured with a Meon General Purpose Moisture Meter.

Do I need a primer?

Refer to TDS as it varies across products. Typically 5°C for solvent based and MMA's, which rises to 10°C for water based and solvent free products.

Why is my paint not drying?

Main reasons are low air temperatures, high humidity levels in the atmosphere [damp weather] and/or lack of airflow/air changes. If it is possible to increase temperature and/or airflow, it may help.

I am laying onto concrete, is it imperative to let it cure first?

Yes, for 3 reasons; firstly the curing process tends to cause laitance [a dusty coating which is a natural part of the curing process] and this will prevent adhesion; secondly the moisture content is very high when first laid and it will prevent adhesion; and finally the coating applied to concrete may well prevent further evaporation of water trapping this within the concrete causing problems later.

Can I use water-based in a chill chamber, around 1-3°C?

Typically the answer is yes, as the chilling process tends to extract moisture from the air and creates a relatively dry atmosphere. The curing time will be extended, we recommend a test patch first to check.

Can I apply your products onto new asphalt or tamac?

We always recommend allowing sufficient time for the surface to stabilise and for oxidisation to take place. It is difficult to put a timescale on this, as it is weather dependent and varies between a few days in summer to several weeks or more in winter. Water based products can be applied a lot sooner than products high in solvents. There are ways of priming if coatings have to be applied immediately. You can see a list of our primers HERE

Do I need to carry out any mechanical prep to a power-floated concrete floor before applying a coating or lines?

We certainly advise it as it will provide a better finish with excellent adhesion & longer life. If it is not possible, there are primers which we recommend as the next best option.

Why are my painted lines flaking off from the surface?

If paint is flaking, it has not adhered properly to the surface. There are several possible reasons for this: 1] dirt or soiling present on the surface; paint may stick to the dirt, but the dirt will come off the surface and take paint with it. Check the underside of the paint flake – is it dirty? if so, that is likely the cause; 2] moisture or dampness on the surface – this needs addressing in 2 parts as follows, with either of them, if the underside of the paint flakes are clean and the product flakes off easily if you drag a coin across then it is very likely a damp issue; 2a] dampness in the substrate – especially in concrete there is often damp just below the surface and this prevents adhesion as the paint does not cure properly; or 2b] condensation collecting on the surface during painting – if the air is moist [high relative humidity] and/or the surface is cold, it is common to have a fine film of condensation on the surface, not immediately visible but sufficient to prevent the paint sticking; 3] air and/or surface temperatures too high, typically 35°C or more; this causes paint to dry too quickly and interferes with the cure process, so it doesn’t stick. Whilst air temperature this high are uncommon in the UK, surface temperatures can easily be in excess of this in warmer weather.

Your Tech Data Sheet gives drying times at 15°C - if the temperature is lower than this, how will it affect the drying time?

These times will approximately double for every 5°C drop in slab temperature.

Why is my paint taking longer to dry than it says in your Tech Data Sheet [TDS]?

The drying & curing times we quote for our products are mostly based on an air & slab temperature of 15°C, with reasonable airflow. If temperatures of either are lower, or airflow is limited, drying times will be affected. These times will approximately double for every 5°C drop in air or slab temperature.

Why is the air temperature in my warehouse or workshop important?

The drying & curing times we quote for our products are mostly based on an air temperature of 15°C. These times will approximately double for every 5°C drop in air temperature, cooler air can absorb less solvent, therefore lower temperatures will affect drying times.

Why are my lines varying in width as I spray?

a. The most common reason is that the spray machine has 2 guns and the short gun hose is being used, rather than the long one. Only use the short gun hose as a 2nd gun!
b. Often running the engine slightly faster can remove some variation in line width.

Do I need to prime the surface before laying UltraLine?

We always recommend priming concrete before application of MMA products, for specific technical reasons. Refer to our Primers section on our website for more detailed information.

Can I leave my tips in thinners for the winter?

Ordinary thinners tend to have a water content which can led to rusting; better to clean them thoroughly and store dry, or store in a high grade thinner [such as X290 SF Thinners] in a sealed container such as a screw top jar

Why is my paint machine leaking a lot of paint around the tip/tip guard?

a. Check the tipseal – it may be missing or incorrectly positioned.
b. Dry paint on end of gun may prevent seal being madec. Check tip guard is hand tight.

How do I dispose of arisings when I am using waterbased paint?

Ultimately it is down to your specific Waste Management policy or practices. Our recommendation is to store the arisings in a bunded area, protected from rainfall, in lidded containers; punch/drill airholes in the lids, this will allow the water content to evaporate. Once the water has all evaporated the solids content will dry and we consider this to be inert & non-hazardous waste; dispose of in the same way as you would dispose of anything else in this category.

What does transport medium font look like?

Visit the Roads website here & scroll down to ‘’Pavement’’ – this shows you what it looks like – bear in mind the taller characters are ‘’stretched’’ [typically 900mm upwards].

Can I rent a paint machine, or do I have to buy one?

We have rental paint machines available, however we do insist that we provide training if you have not had any previous experience, to protect both of us and make sure you get the best out of the machine!

Why do I need to know the temperature of the floor slab in my warehouse or workshop?

The drying & curing times we quote for our products are mostly based on a slab temperature of 15°C. These times will approximately double for every 5°C drop in slab temperature, therefore it has an important influence in deciding which products can be used.


Yes, we do have products and additives which offer good slip resistance when applied correctly to suitable substrates. Typically SRV45 or more is considered suitable for medium risk areas such as walkways, rising to SRV65 or more for high risk areas such as High Friction Surfacing.


This will depends on the surface where it has been applied. Remove with a stiff brush and high jet pressure washer.


As a temporary spray it is designed to last between 2-8 weeks.

How do I put markings on resin bound?

Preformed thermoplastic marking are fine to use, although ensure you don't burn the surface of the resin when applying.  Spray applied water based paints or low solvent based paints such as ViaLine F210 can also be applied.  Paints with a higher solvent level could cause damage to the surface as the solvent may soften the resin.

What are the advantages of using a sealer?

Benefits of using a sealer on a painted line (or area) is threefold.  Firstly it improves the gloss level such that the line is brighter.  Secondly the line is easier to keep clean.  Thirdly it will extend the life of the line.

What paint do we suggest using on rubber crumb surfacing or synthetic turf?

Both of these surfaces require special vulcanised paints which Meon do not currently supply.  The closet we can get is our RouteLine which is only available in a limited range of colours.

Do you have a paint I can use in a food prep area?

We recommend the use of water based paints, rather than solvent based, in food prep and storage areas, as this removes the risk of solvent taint to the foods.  Be careful, as some water based paints have an ammonia content.  Whilst this is a widely used ingredient in water based paints, it can set off ammonia detector alarms if they are fitted to your cooling system.  Use an ammonia-free water based paint.

How can I paint a floor which has oil on it?

Oil stains are one of the most problematic challenges you will come across, as once it has seeped into an unsealed concrete surface it is virtually impossible to remove.  We never recommend overcoating an oil-stained surface as the adhesion will be compromised.  Some form of mechanical preparation is normally necessary to remove the oil residue prior to coating, however there are specialist primers that can help, if the floor has to be coated.

Do I need to wear any PPE when using the ViaLine system?

We always recommend using ''best practice PPE'' with any paint product, by this we mean suitable hand and eye protection.  ViaLine is a low-solvent product, however there is a smell with it, as with virtually any paint product.  If your Risk Assessment recommends the use of a face mask, or if the user suffers from any respiratory ailment such as asthma then it should be mandatory equipment.

Is it right that water based paint will not last as long as solvent based?

This is not correct.  The key thing is the quality of resin, as this is what is left as a paint film after the paint has dried.  Water based paint is widely used and delivers good results.  In the UK we have a damper climate - this is a challenge for water based as it often means that the water based paint does not dry properly when applied in slightly cooler or damper environments such as night time, leading to poor adhesion.  This has given a poor reputation to water based road paints in the UK, but is not a true reflection on the product.  Applied correctly, it can often outlast equivalent solvent based paints.
