✅ GOOD stonemasons, exterior cleaning specialists and facilities management professionals will be aware of this:
🏘 FREEZE THAW CYCLE
This occurs when water seeps into cracks, freezes and expands, eventually causing the substrate to break apart. Moss build on your stonework retains moisture and eventually damages the integrity of the substrate surface.
As chemical suppliers to exterior cleaning contractors, as we head into the winter months, we see lots of examples of this
What you do not want to do is flood exterior surfaces with large volumes of water when cleaning.
This is why we recommend using contractors who use the #DOFF Integra Superheated Steam system which disperses just 5L of water per minute. There is a reduced chance that any moisture at all is left on the surface of the substrate. With its ultra low pressure and 150c steam we produce one of the safest stone cleaning methods on the market.
Once your surface is clean it can then be #sealed with a water based impregnation #sealer Proteger Proshield Facade Sealer thus protecting the surface from damp, frost and moss and algae growth. It’s also makes the surface easier to clean in future.
Please call Jon on ☎️0️⃣3️⃣3️⃣3️⃣5️⃣7️⃣7️⃣9️⃣4️⃣1️⃣1️⃣ or email
We can provide advice or demonstrations using any of our sealers or facade cleaners to both the trade and domestic clients.
