Good Afternoon B Pattie
Thank you for your question.
You can still apply a water based paint to the sandstone, this must be done 3-10 days after application of the Raincheck Water Seal. After this duration you would only be able to apply a solvent based paint.
Any questions please feel free to contact us directly on 01403 210204 or email at [email protected].
