I have a customer that wants to seal their slate driveway.
Is the color enhancer sealer able to be used outside?
Do you have a sealer that can be used outside?
Yes the color enhancing sealer, and the penetrating sealer are both fine for exterior use.
The thing with any sealer, color enhancing sealer included, is the sun will deteriorate the sealer.
With the color enhancing sealer, it will fade with time. If you want to continue with the color enhancing look, just pressure wash and enhance again.
In my opinion, this would be an annual event.
I hope this helps.
