Fast-drying finishes can sometimes be tricky. If you go over the finish with the applicator once the finish has started to dry or “kicked over,” it can create bubbles or make the finish streak. This appearance is caused by pulling the new finish over the partially cured finish. Fortunately, there are many ways to prevent this issue.
Prevention:
Don’t Use Old Finish: Make sure you check the batch codes from the manufacturer of the finish before you lay it down. Expired finishes can be foamy or bubbly, which can affect the way the finish performs.
Lay it and Leave it: Focus on completing the floor a little at a time. Work in an area about 3 by 3 feet—something manageable and comfortable. Once the finish is dry, you can go back to do minor repairs, as opposed to repairing a big area of overworked finish.
Don’t Wring out Applicators: When your “wring out” your applicator during the application process, you are introducing air into the applicator and into the finish you are applying. This will cause foam or bubbles. Instead of wringing out your applicator to remove drips, try just tapping the excess off.
Control the Air Flow: When your coating the floor, make sure the HVAC system is off. This will prevent uneven finish, debris, streaks, etc. Once the floor is finished, wait about 30–45 minutes before turning the system back on.
Add Water: If you are working in high temperatures or low humidity, it can be beneficial to add water to your finish to extend the “open” time. You can add up 12 ounces of water per gallon.
