Troubleshooting Acrylic Sealers: Cob webbing (Looks stringy or like cotton candy)

Cause: Excessive substrate or external temperatures; or pulling sealer too tight Solution: Cob webbing is most common in the hot summer months due to extremes in temperature. It is best to apply sealer in the cool of the day before the concrete has heated. If cob webbing does occur, apply an additional or heavier coat of sealer and the issue will clear up immediately.
