Why Preparation Is Key Before Line Marking

Why Preparation Is Key Before Line Marking

Line marking a concrete surface is an important step in the construction process. In fact, it’s one of the first steps that line marking contractors take when they begin working on a new building. While there are many different types of line markings available for use on concrete surfaces, most require some sort of preparation before using them. This is because any dirt or grime left on your concrete could interfere with the bond between paint and concrete. Here are some tips for making sure your surface is clean and ready for line marking:

Concrete must be clean and dry.

Concrete must be clean and dry. When preparing to line mark on concrete, you need to make sure that the surface is free of dirt, dust, oil, grease and any other contaminants that may prevent the paint from adhering properly.

  • Clean off all dirt with a vacuum cleaner or pressure washer.
  • Use an alkaline concrete cleaner if necessary (see step #4).
  • Remove all debris from cracks in the concrete with a wire brush or grout removal tool before applying your line marking paint (see step #4).

Ensure that no oil, grease or dirt is present on the surface.

Before you begin marking your line, it’s important to ensure that no oil, grease or dirt is present on the surface. If it is, then wash it off with water and detergent to remove any contaminants that may cause damage to the paint.

If this doesn’t work, you’ll need to use a pressure washer and/or degreaser as part of your preparation process. A wire brush can help remove stubborn oil stains from concrete surfaces; if you find yourself faced with these types of stains frequently at work or home, then this tool might be worth investing in for future projects!

Use a vacuum cleaner if necessary (especially when working with carpets) because some vacuums are designed specifically for getting rid of dust particles embedded into rugs & carpets, which could otherwise ruin freshly applied for paint jobs on those surfaces due to their powdery nature (this type of job would require more than just one session). Also note: while vacuuming alone will only get rid of loose dust particles (and not embedded ones), steam cleaning may be required in order to take care of all potential problems associated with cleaning carpets thoroughly prior to applying new coatings over old ones.

Any badly cracked areas should be fixed and patched before line marking can begin

  • Any badly cracked areas should be fixed and patched before line marking can begin.
  • Cracks can be filled with concrete, a sealant or a patch. If the crack is too large to fill with a patch, use sand and cement as a filler instead.

Dust, dirt and grime can prevent a good bond between the concrete and paint.

The first step in preparing your concrete for line marking is to clean it. This can be done with a pressure washer or by applying a chemical cleaner. If you are using a pressure washer, make sure that you don’t overuse the sprayer and soak too much of the surface in water or chemicals.

Next, remove oil and grease from your concrete surface with an appropriate solvent (such as paint thinner) before applying any paint product. When applying sealers on top of old lines, make sure that there are no loose flakes or splinters left behind after scraping away their old markings – these will impede adhesion between new and old layers of paint!

If there are cracks in your concrete due to expansion when wet weather arrives, then use a spackle-type product designed specifically for fixing these types of problems (not just any joint compound will do).

Use this product liberally but do not allow it to become thickly applied like polyurethane sealers used over wallboard areas where two sheets overlap each other closely because those products hold moisture very well, so keep them thinned out as best possible when using them outside during hot summer temperatures since heat reduces bond strength significantly even though most people think otherwise without realizing what actually happens inside their bodies during exercise activities such as running long distances without proper hydration levels being met beforehand.


There are many steps that you can take to make sure that your concrete is ready for line marking. The most important thing is to ensure, as per the line marking contractor services, that the surface is clean, dry and free from any dirt or dust. Once this has been done, you can begin preparing the concrete for painting by using a primer or sealer. This will help protect against chipping, peeling and fading due to weather conditions such as rain and sun exposure.
