The weather can be a Linemarker’s best friend or worst enemy, and inclement weather conditions can make line marking a real challenge!
The following seasonal conditions can all play havoc on line marking projects:-
If it’s raining or the forecast is predicting certain rain, leave line marking well alone!
Job completion can be accomplished by dancing in between showers, however standard coatings are going to require drying time and you could end up with a situation where rainfall on fresh coatings rejuvenate the paint causing it to retard its dry time.
Ideal drying time for standard coatings is at least four hours under normal working conditions, with coatings not fully cured for up to seven days.
So if you are line marking a busy car park this could result in a wet paint mess.
- Humidity and Damp Surfaces
Humidity can severely change the drying time of coatings. High humidity can cause surfaces to be damp and not ideal for superior bonding to the surface. It can also make coatings take longer to dry.
Areas to be line marked need to have dried out completely otherwise moisture still retained within can migrate to the surface pushing the coating off with it, causing delamination.
Too cold, you will have slower dry time.
Too hot, your coating will dry super-fast and possibly cause a ‘false set’ meaning it has skimmed over and dried on top, but may not be fully dry under the skim coat.
Extreme heat can also make line marking paints challenging to apply if rolling, and tape removal can become messy and even cause damage to painted surfaces when removing as they ‘over dry’ together with the line marking.
Windy conditions are not favourable for line marking either.
As most line marking is applied through an airless spray machine, wind can carry paint particles aimed at the surface with it onto nearby objects such as vehicles, walls and windows and these types of fix ups can be difficult and costly.
- Low Visibility
Particularly during the Winter months, visibility can make it quite difficult to complete any sized line marking project.
Fog and declining daylight are conditions to be considered when planning outdoor works. Task lighting can work in smaller projects, however, if the requirement is to ensure every line is straight and even, overall area lighting will be required.
To ensure you prepare, keep the following measures in mind:
- Don’t leave your line marking to the very last minute
Plan ahead. Check the weather forecast and be guided by your line marking contractor – they will know the weather risks they are willing to take to ensure they achieve the best results for your project.
- Have a backup date where possible
For outdoor projects, dates are always booked in with a ‘weather permitting’ clause. Be prepared to be flexible should the weather turn by having an alternate date available. This will ensure your contractor can set placeholder dates in their calendar for your project if required.
If your project is pushed out by weather, it could cause a backlog in jobs for your line marking contractor so this measure will ensure you have a backup date already locked in.
- Ensure the job can be completed as efficiently and quickly as possible
The last thing you want is to be disorganised when your line marking contractor arrives on site causing delays at the front end of the job if the weather is looking set to turn for the worse.
Streamlining the process by having the area clear of vehicles, equipment, excessive dirt, etc will ensure your line marking contractor can get in and on with the task at hand as quickly as possible.
A great line marking company will have worked out how much time they will need on site and what they can complete before the weather changes.
- Test your surface area for humidity
If moisture retained in your surface is a concern, a moisture meter can be used to detect levels and quickly determine whether it is safe to proceed with your line marking.
Ask your line marking contractor to take a moisture reading to provide certainty.
- Removing puddles and pooling water as soon as possible
Removing pooling water on the surface by way of brooming or blowing down will help the drying process immensely. If there have been periods of heavy rainfall and there’s a break in the weather, get the project started using this simple process.
- Ensure suitable lighting is available
If your project needs to be completed after hours, or during the darker months of the year, your line marking contractor will require some form of lighting over the surface area.
Ensure your car park lighting is operational, remains on for the duration of works and will not automatically switch off at closing time.
- Consider coatings suitable to conditions
Certain line marking paints work best in differing seasonal conditions. Check with your line marking contractor the best product for your project.
If the requirement is for high visibility, for example in loading docks, consider a long life option with high reflectivity and long lasting colours for high traffic areas.
