I have a variance in the sheen of my sealer in places, should I apply a third coat?
Ask a Pro
Q. - I just put 2 coats of sealer (clear shield advanced from concrete camouflage) on my floor last night. When i checked it this morning you can still see a variance in the sheen it a few places. Do you recommend a third coat or will the wax take care of this? BTW the artist grade concrete stain by concrete camouflage did a great job on the acid etched floor. Thank you.
I would go ahead with another coat of sealer to smooth it out, before applying the wax. The wax may take care of it, but if it doesn't then you'd be removing the wax and applying more sealer anyway.
However, if you don't have enough sealer to do a third coat, you should do a test before ordering more. You can put a two foot square section of wax down, that half of it covers a smoothed out part and half of it covers a lower sheen part. If it works out then you can go ahead and apply your wax. If it doesn't work and you see you'll need to apply more sealer, then strip off the wax with Simple Green and go forward with your third coat of sealer.
Tip: Now that we're in Summer time heat, it's important to remember that the sealer will try to dry faster which can cause sheen variance and/or roller marks much more easily. Therefore, try to do all sealing in the cooler part of the day, and preferably in shade, if possible. Early morning is really the best because the concrete isn't heated up from the day, as it's had all night to cool off.
Also, thank you for the report on the artist grade concrete stain working well on your floor, which had been previously acid etched. While acid washing or acid etching concrete renders standard grade concrete stains useless and unable to work, it's nice to hear the Artist Grade Concrete Acid Stain by Concrete Camouflage is still doing the job that the others can't.
I hope this helps.
