What to consider when choosing a resurfacing system

When deciding which resurfacing system to choose, here are a few simple questions you need to ask in order to find a system that will best serve your needs.

What is the condition of the existing surface?
If the concrete has a lot of cracks or gouges or if the surface is not level then it would be best if you selected a higher-build material, such as a self-leveling product. A stampable overlay, which is applied at a 1/4-inch or greater thickness, would also be good.

If the concrete contains too much moisture then you should use a permeable overlay system, which will allow the moisture vapor to escape.

What type of conditions will the overlay be exposed?
The topping or overlay system you select has to be durable enough to withstand all elements and conditions it will be exposed to such as extreme temperatures, weather,
chemical, grease, dirt, or oil. Most coatings will withstand wear, however other systems are more suited to withstand chemical spills and dirt penetration as well as harsh weather. For aggressive environments, materials containing aggregates will perform better in these harsh conditions.

How difficult is it to mix and apply the product?
Generally, the most difficult part of applying any coating or overlay is the preparation. However, with some products, all you need to add is water while others require mixing
other dry ingredients as well as the polymer additive and desired pigmentation. In addition, several overlays can be applied directly on properly prepared surfaces, while others require the use of a primer or bonding agent. Pourable and self-leveling systems usually cover surfaces quicker and with less finishing work than troweled or sprayed applications.

How much maintenance is required?
Sealed surfaces are simpler to clean and many times they only require routine sweeping and occasional damp mopping with a mild detergent. However, some overlay manufacturers
recommend that the surfaces be resealed annually.
