How to get rid of discoloration on a concrete surface? Especially in the hot season, the phenolic resin
coating is exposed to intense sunlight, which can leave a brown colour on the concrete surface. This
undesirable problem can be minimized or even prevented.
Have you seen the discoloration? This brown \u2014 sometimes curved \u2014 discoloration that appears on the
concrete surface when the formwork is removed? The bad news is that when using phenolic resin plywood, regardless of the supplier, discoloration is very likely to occur because the properties of the plywood are resistant to ultraviolet radiation. The good news is that you can reduce the damage and even prevent it if you carry out the following simple steps.<\/p>\n\n\n\n

How to get rid of discoloration on a concrete surface? Situation 1 | You use phenolic resin plywood and want to reduce discoloration<\/h3>\n\n\n\n
    \n
  1. Minimize exposure of the phenolic resin coating to UV radiation
    Protect plywood from intense sunlight, e.g. by storing it vertically with concrete surfaces they should be in contact with each other, or you can cover them.<\/li>\n\n\n\n
  2. Watch out for residue
    Keep the formwork clean before pouring the concrete. Before use, remove any dirt, rust, or fingerprints from the plywood surface.<\/li>\n\n\n\n
  3. Adjust the construction cycle You have to loosen the tie bars in each panel and remove them from the concrete immediately.
    Otherwise, the formwork panels may likely move away from the concrete surface in some areas while continuing to be attached to it in other areas. This can create a gap between the hardened concrete and the formwork where condensate water, dirt, concrete, or release agent residues and\/or dissolved phenolic resin will accumulate.<\/li>\n<\/ol>\n\n\n\n

    How to get rid of discoloration on a concrete surface? Situation 2 | You used phenolic resin plywood and want to remove discoloration<\/h2>\n\n\n\n

    In some cases, discoloration of concrete surfaces can be effectively removed with a mild acid such as
    softly concentrated formic acid. An alternative is the use of professional cleaning agents (however, it is
    recommended to consult a concrete or stone cleaning company beforehand). Mechanical removal tools
    are also an option, e.g. You can apply the process of grinding and patching. Any removal steps should be
    first carried out on the area dedicated for testing, as the methods may get negative results instead of
    improving the surface condition. They can even deteriorate the appearance of the concrete surface or
    highlight defects on the surfaces.<\/p>\n\n\n\n

    Situation 3 | You want to prevent discoloration altogether<\/h3>\n\n\n\n

    The best way to prevent discoloration caused by phenolic resin is, of course, to use alternative
    thermoplastic plywood.<\/p>\n\n\n\n

    HOW TO CLEAN CONCRETE? WITH WHAT LIQUID TO REMOVE OIL, GREASE AND OTHER CONTAMINANTS? Discoloration ON A CONCRETE SURFACE<\/h2>\n\n\n\n

    There is no shortage of chemical products on the construction market that will remove dirt from concrete.
    The problem is that such chemicals may affect negatively the environment and human and animal health. That is why Innovatech has developed an innovative formula that can clean concrete and keep the environment safe.     Betoff-Bio<\/a> is a fluid based on an endemic plant that removes all dirt from concrete surfaces and more. Cleaning companies use Betoff-Bio<\/a> to clean the facade, and all kinds of stone, and also to clean the joints. Betoff-Bio<\/a> is the only such liquid on the market, and its composition and mixing technology are a strict secret. This liquid can also remove cement and lime stains from windows, zinc, plastic surfaces, and even rubber elements.<\/p>\n\n\n","protected":false},"excerpt":{"rendered":"
