Building exterior paint performance in tropical salty environment of Lagos

Materials that are used for exterior finishes of buildings are their last line of defence against the elements of climate. The compliance of the materials with the environment will determine their performance and consequent repainting. A high percentage of buildings? exterior surfaces are finished w...
