Limestone should be free of dust and dry prior to sealing. A low-pressure garden spray or similar device is ideal. Apply from the top of the stone and work down the wall. For areas close to windows and doors the sealant can be applied using a paint brush. Whilst reconstituted limestone, being a manufactured product, is denser it can still discolour and therefore it is advisable to seal the stone if the original colour is to be retained.

If limestone is sealed correctly the first time, it should not require further sealing for many years. See similar questions...

quot;I have recently painted the walls but the basement is still very damp. Can I still seal it against moisture?" Sorry, you have to remove the paint first. But if the paint is just a single layer of latex-based paint like Drylock, it is porous and does not stop water vapor - humidity.
