After sealing the concrete and you have bubbles, how long do you wait before you apply the xylene?
A. You can apply xylene to concrete sealer blisters and bubbles as early as 24 hrs after first applying the concrete sealer.
Use a stiff bristled broom to break the bubbles before applying the xylene. Spray a thin coat of xylene on the surface using a pump up sprayer. The xylene will re-wet the sealer, back roll with a 9 inch paint roller immediately after spraying to break up any remaining bubbles.
Make sure the weather is dry and rain isn't in the forecast for 24 hrs. Do this early evening when the sun is going down and the temperature is cooling.
Xylene is a solvent, is flammable, and has a slight odor. Wear the proper clothing and use caution when applying this product.
