What is the Best Solution for Concrete Resurfacing?

Concrete Floor Resurfacing

The USA Concrete Repair Industry has grown to 2.6 billion in 2020 and will continue to grow at a clip of nearly 5 percent through 2027.  Obviously, there is a need for concrete resurfacing and a growing need for solutions to projects worldwide.  The best solutions to repair failing concrete involve strengthening the failing surface with a penetrating sealant and adding a top coat, high strength coating that can withstand heavy traffic, all weather conditions and chemicals.  Depending on the scope of the project, there are some variables regarding the best solutions for concrete resurfacing.

Step 1: Concrete Surface Preparation

Concrete must be cured a minimum of 7 days at 75°F (24°C) and 50% relative humidity or equivalent. Prepare surfaces in accordance with ASTM D4258 Surface Cleaning of Concrete and ASTM D4259 Abrading Concrete. Voids in concrete may require surfacing. Mortar joints should be cured a minimum of 15 days.

Step 2: DX1100 Concrete Resurfacing Primer

DX-1100 Concrete Resurfacing Primer is a deep penetrating epoxy that sinks within the pores of the concrete, strengthening the structure and allowing an excellent bond for the top coating to adhere to.

DX-1100 Features

  • Low viscosity, deep penetrating sealant
  • Eliminates outgassing caused by traditional primers
  • Increases adhesion to concrete due to deep penetration 800 psi or greater based on ASTM D4541
  • Easy brush/roller/spray application
  • Adheres to damp concrete
  • 100% solids and entirely free of solvents and VOCs

Recommended Uses

  • Damaged concrete, cement and stone surfaces

Step 3: Apply PANSEAL Top CoatAbrasion Proof Coating

PANSEAL Abrasion Proof Coating is an ideal top coat for concrete surfaces because it can withstand heavy traffic, all weather conditions and chemicals.  When applying PANSEAL make sure to stay within the re-coat window of DX-1100 – see this link to DX-1100 Product Data for re-coat information.

  • Easy brush/roller/sprayer, self-level application
  • 100% solids and entirely free of solvents – NO VOCs.
  • Works on metal, fiberglass, stainless steel, concrete and wood surfaces
  • Bonds chemically and mechanically to the substrate
  • Excellent adhesion strength – 2,750 psi (pull-off adhesion test ASTM D 4541)

Power mix part A resin separately, then add part B hardener and power mix.   Pay attention to the sides and bottom of the bucket and mix to obtain a uniform color.

Once mixed be ready to apply. Do not keep the blended coating in the original container unless immediate use is planned.  Otherwise, exothermic heat created during the curing process will considerably shorten the pot life.  Pour the coating into a rolling tray or pour directly onto the surface.  Try to keep the depth of the coating in the tray below 3/8”.

Brush:  Use a medium bristle brush.

Roller:  Use a short-nap synthetic roller cover with phenolic core.
