Sealit it with Lanco

This great for the trailer of my friend who has Parkinson there is no way she could do here roof It's been years since someone did this roof as you can tell from the Pic's 1st scrub with a cleaner using a brush, then power wash it and put Lanco's Roof Sealer on I let it dry for a few hours as the sun in Central FL will dry things out. I applied 2 more coats and did here 8x10 Shed with one coat. I use white in Central FL because .... SUN lots of SUN
