Posts: 35 07/20/10 06:33 PM	Tags : None Anyone experience air bubbles in CSS, i had it happen the other day in a very limited area, but made me remember using another acrylic sealer where we had it happen alot. it seems to happen when it is very hot, i think when the sealer is a little to thick and the top dries before all the air has escaped, thus making a bubble. but i may be wrong, just wondering what you all have experienced. thanks Nate

I'll even time my application when the sun goes behind some clouds. As was mentioned, early or late in the day will serve you better. gene ec-Indy

If not, I would thin css 2 to 1 or even 3 to 1 if you have to. I would spray it with either a high quality pump sprayer or hvlp gun and you will have to do multiple coats to get your film build. Easier to just do it in the cool of morn if possible. Good Luck Scott ps I had a patio that would bubble even in morn. I finally had to reduce 4 to 1 and do 2 coats before it sealed off.
