Cast stones have been a versatile architectural feature ever since the 12th century. This is a great material for creating decorative features such as ornaments and trimmings. Cast stones are often used to add aesthetic features to outdoor areas. Outdoor structures wear faster than those indoors, which is one reason why cast stone repair is vital to the care and maintenance of cast stone structures.
Luckily, there are many ways that cast stones can be repaired. The most important thing to remember when seeking cast stone repair is that the work is meticulous and must be performed by a trained hand. Your regular handyman will not be able to do this job properly—you need a certified cast stone repair professional.
Cast Stone Repair Facts
Cast stone repair has many nuances that a regular handyman would not take into consideration. Read below to find out why these nuances are so important.
- Early morning is the best time for patching.
One common method of cast stone repair is patching. Stonemasons add a new layer of concrete over the damaged portion prior to restoring it. Patches are only effective in certain temperatures. In order for patches to be effective, the temperature of both the air and the stone must exceed 40 degrees Fahrenheit. They must remain at this temperature for 24 hours after the patching is completed. Patching in the afternoon raises the risk of higher temperatures, which inhibit the effectiveness of the patch.
- Damage visible within 20 feet should be patched.
Before opting for a patch, try cleaning your cast stone. If you can still see the damage 20 feet away after cleaning, then patching is a good option for your cast stone repair. If you cannot see the damage at a 20-foot distance, talk to your stonemason about other options.
- Proper patching takes 12 steps.
Many regular contractors assume that patching takes only four simple steps, but this is false. Expert stonemasons know that patching is an intricate 12-step process. Even simple stone patching jobs require 12 steps. The first 4 steps involve mixing and preparation. Next, you have to drench, spray, press, and smooth the patch. Once the patch sets, it must be burnished and then covered for 24 hours. Five days later, it must be washed with a stone cleaner.
