Horizontal Resurfacing

Over time, horizontal concrete surfaces suffer surface deterioration due to heavy use, abrasion, ice, salt or age – a common problem for light commercial and residential projects alike. When it comes to concrete surfaces, the most cost-effective way to get a “like-new” look is to simply resurface.

According to Andrew Fulkerson, MAPEI’s Concrete Restoration Systems Technical Manager, the two common scenarios eligible for horizontal resurfacing are existing concrete and repaired concrete. Here’s why: Once the installer determines that the concrete is only visibly damaged, resurfacing offers a simpler solution opposed to total reconstruction, saving time and money on a jobsite.

Fulkerson said that MAPEI’s comprehensive range of products includes solutions for patching, priming, resurfacing and sealing horizontal surfaces.

•          Patching: For a high-performance concrete patch, MAPEI recommends patching spalled areas with Mapecem Quickpatch, a fast-setting, gray cementitious material that can blend naturally with existing concrete.

•          Priming: Once the patch is applied and cured, installers follow up with a 3-to-1 mix of water and Planicrete UA, a concentrated liquid latex admixture perfect for priming.

•          Resurfacing: To disguise and hide repaired areas, Concrete Renew can be applied by trowel, broom, plaster pump or hopper gun for a “knock-down finish.” This high-performance concrete resurfacer is also freeze/thaw-stable for use in areas with snow and ice. Concrete Renew can be tinted with colorant suitable for concrete and can also be used over stencils that will provide an aesthetic look similar to stamped concrete.

•          Sealing: Once the second or third application of Concrete Renew is installed, it can be sealed with Mapefinish Wet Look, a clear, water-based acrylic sealer for all types of concrete.
