Offered the number of coats on the Winchester home, Clark had no doubt about the visibility of the heavy metal. In the past, scraping lead paint required employing a certified-- as well as pricey-- reduction contractor to get rid of and also get rid of the lead-laced paint. For Clark and also staff, it indicated that they can do the job-- if they took the mandated safety and security precautions-- which all the paint they eliminated from your home might merely be gotten up and chucked into the trash.

Repaint Stripping Techniques
