Do I need to seal after staining? Is the temperature a factor when concrete staining?

   Q. -  My project is covered porch.  Will I need to seal after staining?  Is outside temperature a factor in concrete staining?

Hello Evelyn,

 

    A. -  You do not need to seal the concrete if using the Artist grade concrete acid stain, though it does add to the look.

The temp needs to be a minimum of 35 degrees F to stain and not going to get below freezing for at least 4 hours, preferably for 12 hours.

   To seal, it has to be 45 degrees F and not going to get below freezing for at least 12 hours and preferably 24 hours.

 

   There is no real maximum temp but you should try to not stain and/or seal in extreme heat, such as 95 degrees F and above. Rather, try to do it in the cool part of the day when in summertime or in very hot areas.

 

I hope this helps.
