roof coatings
Posted on June 24th, 2010 by admin
There are three types of nonconventional roof coatings: solvent, water-based, and 100 percent solids. Not all are considered mainte- nance coatings. Solvent coatings use organic solvents and can be applied over a wide range of temperatures. They dry quickly when humidity is high, but they usually contain large quantities of flamma- ble and often highly toxic organic solvents. Extra care must be taken when httpwww.proroofing.catoronto-roofing-contractor.html transporting, storing, and applying these coatings. In addition, solvent-based coatings are associated with staining problems on cer- tain asphalt roofs.
Water-based coatings use water rather than solvent as the carrier. This eliminates the flammability and potential toxicity hazards linked to solvent-based systems. Cleanup is done inexpensively with soap and water. These coatings can even be applied to a damp substrate without losing significant performance.
