Frequently Asked Questions – Surface Marking

Application Conditions

Application Conditions

1. What is minimum temperature I can lay product at?a. Refer to TDS, as it varies across products. Typically 5°C for solvent-based & 10°C for water-based and solvent-free products

Do I need a primer?

Refer to TDS, as it varies across products. Typically any existing thermoplastic, concrete surface or cementitious substrate [e.g. blocks, pavers] will need priming.

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. There are ways of priming if coatings have to be applied immediately. You can see a list of our primers HERE

Can I apply UltraLine onto concrete without primer?

We always recommend priming concrete before application of MMA products, for specific technical reasons. However, the UltraLine is a ‘thick film’ MMA and is widely used on external concrete areas without primer with very high success rates. Please refer to Technical Data Sheet for more information.

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 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.

Spray Machines and Equipment

How long does the ES 1000 take to charge up?

It takes ~3 hours to charge a dead battery to 80%. It takes ~5 hours to charge a fully depleted battery (double these times for 2 battery unit).

Should I keep my ES 1000 machine on charge all the time or just after I have used it?

All the time!! Lead acid batteries can self-discharge in as little as 3 months depending on storage temperatures. The hotter the storage temperature, the faster the self-discharge occurs. To prevent damage to the battery, it is important to keep the battery in a charged state. Also, a battery that is discharged to 50% depth will get over twice as many cycles in its life compared to it being discharged to 100% depth each cycle.

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.

Why is the charging voltage varying on my ES 1000 machine? Sometimes it is 15v or more, sometimes only 12-13v.

Battery will charge to 14.6-14.8 volts and then it will come back down to ~13.6 volts when fully charged.

Why is my ES 1000 not charging?

If the battery charge drops below 10.5 volts the charger will not work and battery will need a ‘’force charge’’ from an external source, e.g. another battery via jump leads.

Why has my ES 1000 charge dropped below 10.5 volts?

The battery will not drop this low during normal use, as the machine cuts out at 11 volts or thereabouts. The usual reason therefore is that an external accessory has been left switched on, for instance laser guide, LED worklight, flashing beacon.

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 often should I be applying piston lubricant [also known as TSL or throat seal lubricant] to my paint machine?

We recommend to apply at end of every shift as it will extend the life of the pump seals if you do. How to Apply Piston Lubricant video and step by step process

Why is there paint and/or thinners leaking from the pump on my paint machine?

Pump seals are worn & need replacing. [This is sometimes called ‘’repacking’’ the pump]. Pump Seal Kits are available from Meon, or alternatively you can get a module one machine service which includes a new pump seal kit.

how long does the battery take to recharge on your electric paint machines?

A full recharge takes around 5 – 8 hours, depending on model. that said, it would be unusual for any of the models to have a fully discharged battery, so it would usually be less than this.

How long does the battery last on your electric paint machines??

They are all designed & tested to last for at least a complete shift. the actual capacity depends on model, & whether it is single or dual battery. Some last much longer than a shift, so please discuss for more detail.

I need training on a paint machine - do I have to come to your office in Portsmouth?

We are happy to train at your location, as long as it meets a few criteria. These would vary according to what we are training you to do, so please have the discussion with us. That said, we do have an excellent training academy resource here at Portsmouth which you are welcome to use!

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!

Disposal and Waste Management

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.
