2. Roof coating - Wikipedia

   en.wikipedia.org/wiki/Roof_coating

   This means a roof coating actually becomes the top layer of a composite roof membrane and underlying system. As such, the roof coating is the topmost layer of protection for the membrane, receiving the impact of sunlight (both infrared and ultraviolet (UV)), rain, hail and physical damage. Roof Coatings should not be confused with deck coatings.

3. Rust converter - Wikipedia

   en.wikipedia.org/wiki/Rust_converter

   Rust converters are chemical solutions or primers that can be applied directly to an iron or iron alloy surface to convert iron oxides into a protective chemical barrier. These compounds interact with iron oxides, especially iron(III) oxide , converting them into an adherent black layer ( black oxide ) that is more resistant to moisture and ...

4. Chromate conversion coating - Wikipedia

   en.wikipedia.org/wiki/Chromate_conversion_coating

   The chromate coating process starts with a redox reaction between the hexavalent chromium and the metal. [2] In the case of aluminum, for example, Cr 6+ + Al 0 → Cr 3+ + Al 3+ The resulting trivalent cations react with hydroxide ions in water to form the corresponding hydroxides, or a solid solution of both hydroxides: Cr 3+ + 3 OH − → Cr ...

5. Encasement - Wikipedia

   en.wikipedia.org/wiki/Encasement

   Encasement is the coating over, covering or "encasing" of all building components, interior and exterior. This includes all roofing and toxic hazards materials, such as asbestos, lead-based paint, mold/mildew and other harmful substances, found in buildings. The technique of encasing all building components, including unsafe ones, with green ...

6. Metal roof - Wikipedia

   en.wikipedia.org/wiki/Metal_roof

   A metal roof is a roofing system featuring metal pieces or tiles exhibiting corrosion resistance, impermeability to water, and long life. It is a component of the building envelope . The metal pieces may be a covering on a structural, non-waterproof roof, or they could be self-supporting sheets.

7. Primer (paint) - Wikipedia

   en.wikipedia.org/wiki/Primer_(paint)

   Primer reduces the number of paint coats needed for good coverage and even color. A thin layer of paint may still be permeable to water. Water can permeate into the wood and cause warping, mildew, or dry rot. Primer improves the waterproofing of the finish. [4] Primers are not used as part of a wood stain treatment because they obscure the wood ...
