Concrete temperature and wind conditions often determine success or failure for an acid stain project. Hot, dry conditions can cause acid stain to prematurely dry before properly reacting with the concrete.

Sealing Outdoor Concrete in the Summer

Finding the right time of day to apply concrete sealer during the summer months can be a challenge. Sealers should be applied when the concrete is at its lowest temperature either early in the morning or late in the evening. East facing concrete should be sealed later in the day and west facing early in the morning. Colored concrete in direct sunlight, especially dark browns and black, could be several times hotter than the ambient temperature and just a few minutes of sunlight will raise the surface temperature very quickly. When the slab is hot, air passes through the concrete at a faster rate causing more air bubbles and the sealer resin often dries before the solvent or water can completely evaporate.

Summertime Sealing Tips:

  • Apply sealer in the early morning or early evening depending on the location of the concrete.
  • Avoid applying sealer to concrete in direct sun, especially countertops.
  • Do not apply sealer to concrete hotter than 85-90F
