What causes bubbling of a sealer or stain, and what can I do to prevent and/or repair it?
- In most cases moisture is the cause of bubbling of a solid color concrete stain or sealer. Always allow 24 hours of dry weather after rain before application.
- Sometimes over application of solvent-based products can cause bubbling as well. Two thin coats are ideal versus one thick coat.
- If the concrete is too hot at the time of application this can cause bubbling too. Do not apply if the surface temperature is over 100°F.
How do I solve the bubble issue?
For solvent based products, sand with a medium grit paper to knock down the bubbles (do not clean off sanding dust) then roll out a thin coat of xylene to re-wet the material. For water based products, sand using a medium grip (clean off sanding dust) then apply a new coat to cover the damaged areas.
