The need to seal limestone is important for anyone who has a limestone fireplace. Since limestone is a natural product, it is porous and needs to be sealed in order to be maintained properly. Here are the basics of how to seal a limestone fireplace effectively.
Step 1: Clean the Area
The first thing that you need to do is thoroughly clean the limestone fireplace before sealing it. If you do not clean it, anything that is left on the surface of the fireplace will be sealed into it. Start off by sweeping off any dust or dirt from the surface, using a dustpan to remove it. Then use a limestone cleaner and a rag to thoroughly clean the surface.
Step 2: Apply the Sealer
Once the area is thoroughly cleaned, you want to apply a sealer that has been recommended for limestone. Dip a paintbrush or rag in the sealer and then apply it liberally to the surface of the limestone. Make sure that every bit of it is covered.
Step 3: Allow to Dry
Once you have applied sealer to the entire surface of the limestone, you will want to allow to dry. Set up some fans pointed at the surface to speed up the drying process.
