Asphalt Coating
What is Asphalt Coating?
Asphalt Coating, A liquid bituminous material applied to protect concrete, steel, or roofing from moisture and corrosion.
Description
Asphalt Coating is a brush, spray, or roll applied bituminous compound used for dampproofing foundation walls, priming steel pipe, and sealing built-up roofs. Formulated with asphalt cutbacks or emulsions, coatings cure to a waterproof film that resists chemicals and ultraviolet light. Proper surface preparation, dry film thickness, and recoat intervals are essential for ensuring optimal performance and adhesion.
FAQs
Where is asphalt coating applied?
Foundation walls, metal tanks, steel pipe, and built-up roof surfaces.
What types of asphalt coatings exist?
Solvent cutback, water-based emulsion, and fiber-reinforced mastics.
How thick should asphalt coating be?
Typically 40–60 mil dry film thickness for dampproofing.
Can asphalt coating be painted?
Aluminum asphalt coatings provide a reflective finish; other types need compatible paints.
Is asphalt coating UV stable?
Standard coatings degrade; reflective topcoats extend life.
Who applies asphalt coatings?
Waterproofing contractors or roofers using sprayers or brushes.
Are asphalt coatings low VOC?
Emulsion formulas meet modern VOC limits, and cutbacks are restricted.
Fun Fact
Fun Fact: During WWII, asphalt cutback coatings protected thousands of miles of military pipeline from corrosion.
