Let mile high bin sealing, keep your bins dry and looking new. We use a hot rubber sealant that has to be heated up to 400 degrees before its applied. The rubber stays flexible in all weather, wont crack, sticks to almost any other surface or material. Protects metal from rusting. We can apply the hot rubber to new grain bins and old bins, inside and out. Works great on metal roofs and quonsets. We also paint farms, quonsets, oil tanks, corrals, morton buildings, and houses. We also provide flat roof coatings.
