Repairing stone porch stairs is, thankfully, not something that you will need to do very often as stone is very durable and not so prone to weather and moisture. After a number of years, the heavy usage that your porch stairs will endure can eventually cause the stone to become worn and slippery, necessitating important repairs. Repairing stone porch stairs is normally quite easy, especially if the repairs are carried out sooner rather than later. One popular method of repair involves using epoxy, the method described in this article.
Tools and Materials Needed:
- Epoxy filler
- Putty knife
- Soft brush
- Scrubbing pad
- Powdered epoxy dye
- Seal remover
- Clear epoxy
Step 1 – Prepare the Surface
Before beginning, it is important to properly prepare and clean the surface. Use an appropriate cleaning agent and rags to clean the surface that you need to repair. If there is any loose stone on your porch stairs, you will need to remove it before continuing. Use a chisel to break away any broken fragments.
Step 2 – Strip Down the Surface
If the surface of the stone is covered by a sealer, such as a wax surface, this needs to be stripped away before continuing. To remove the sealer, you will need an appropriate chemical seal remover. This needs to be applied over the surface of the porch steps where you are to carry out repairs. Leave the seal remover to work for 15 minutes. You should then be able to scrape away the old sealer using the putty knife. Remove it thoroughly and then use a scrubbing pad to clean the surface. Finally, rinse the surface with clean water and leave it until it is thoroughly dry.
Step 3 – Mix the Epoxy Solution
Mix the epoxy solution in a large enough bowl, using the manufacturer’s instructions for further guidelines. Add the powdered epoxy dye to the mixture. This will give the mixture the same color as the stone that you are repairing. Ideally, the epoxy mixture should be slightly darker in color than the stone itself. Add more pigment until you get this effect.
Step 4 – Apply the Epoxy Filler
Any chipped areas should be filled in with the epoxy filler that you have mixed. In sections where stone has broken apart, the epoxy filler can act as a glue to hold the two parts together again. Spread the epoxy evenly and thoroughly over the surface using a putty knife. Make sure that the surface is smooth and then leave it to dry.
Step 5 – Finishing Up
When the surface is dry, sand it down lightly. Remove any dust or epoxy residue with a dry cloth. Finally, apply a layer of clear epoxy sealant over the repaired surface. This will create a water-tight seal which will hold the epoxy in place and protect the surface from further damage. Again, apply this using the putty knife as directed by the manufacturer’s instructions. Before using the steps, leave the surface for 24 hours to dry thoroughly.
