Most exterior paints will cover about 400 square feet per gallon for one coat. But adjust for waste factors like the type of surface and equipment used. If the surface is rough or porous, add 20% to the total gallons figured. If siding is narrow (4 to 5 in.), add 10%. If on a corrugated surface, add 33%. Also add on a 10% waste factor if using brushes or rollers, add 20% for airless paint sprayers, and add about 40% for air paint sprayers.
The best way to prepare for a flood is in the planning stage of a new home. FLASH recommends an evaluation and inspection of your homesite and lot prior to construction to determine the flood zone and the Base Flood Elevation or BFE. The BFE refers to the elevation associated with the “100-year flood,” or a flood with a 1% chance of occurrence in any given year. The “100-year flood” patterns form the basis for the National Flood Insurance Program rates and regulatory floodplain management.
