Decks oftentimes go through various kinds of problems, depending upon their function, location and construction method. Deck deterioration arises many times as a result of concrete reacting with external elements such as air and moisture. This happens especially because deck structures are mostly made using concrete. In case of such misfortunes, residents of Brisbane can benefit from the expert deck repairs Brisbane – http://deckrevive.com.au/ offers today.
You can use the signs below to effectively monitor the deterioration of decks.
1. Cracking and spalling
Decks might show rents and cracks, indicating severe strain of concrete. Such strain could arise from sudden freeze-thaw action.
2. Laitance formation
An excessive amount of water applied when mixing concrete could form laitance, a thin layer of cement which rises to the surface once the mix has been poured.
Presence of white crystalline substance atop the concrete surface indicates residue deposits of salt arising from exposure to moisture.
4. Concrete surface cured incorrectly
Decks need to be cured for 30 days at least before application of deck coatings can be done. The high content of moisture on the surface would otherwise occasion coatings failure.
5. Corrosion of reinforcing steel
Decks employ reinforcing bars for better structural integrity. A rust-colored stain appears on deck surface when steel gets corroded, indicating threatening of structural integrity.
6. Deck Repairs and Coating Applications
You could enlist the help of professional coating contractors for the purpose of assessing how severe deck deterioration has become. The problem may not be fixed by just any amount of deck coatings, in severe cases of damage to the deck.

The deck should be rehabilitated if the reinforcing steel seems to be corroded.
7. Protective Deck Coatings
Products for coating decks get designed while having in mind the porosity of concrete. Such products prevent penetration of moisture or soluble salts onto the surface. Other products offer resistance to chemicals, corrosion as well as freeze/thaw resistance. The choice of coatings relies upon the specific requirements of a particular deck.
Protective coatings usually comprise thick-film formulations which provide some barrier protection. This could be from epoxies, acrylics, vinyl, elastomerics and polyurethane. They provide the benefits of flexibility and waterproofing to deck structures.
Surface preparation performed before the application of deck coatings generally aims at attaining a rougher profile for better adherence of coatings.
Any moisture traces require being removed from the surface of the deck before coatings are applied, as it prevents surface blisters. A moisture test needs to be conducted to ensure low to zero content of moisture is achieved.
8. Water-Repellant Deck Sealers
The water-repellant abilities of sealers come in handy within exterior areas like parking lots, where greater chances of exposure to water exist.
Thin-film sealers, unlike thick-film coatings, penetrate concrete, filling up every pore within the area, which leaves no space for penetration of water. Sealers need a surface which is clean completely. Oil, dirt, or grease has the capacity of preventing sealers from permeating the deck surface totally.
