The presence of holes in the concrete floor is often a sign of failure industrial floor coatings. If the concrete surface with a film coating, the air between the surface and the coating captured. To obtain a chemical reaction causes a temperature hot air trapped at the surface and force their way out, making the shallow crater-like depressions or holes.
In addition, when the liquid coatings for industrial floors are within minutes of the concrete corners and openingsThe air is expelled from these curves, and trips to the nearby areas. If the air displaced have gathered enough strength, which eventually becomes a mini-break on the form of pinholes.
The cause of pinhole formation should be identified, implemented immediately with the solution to the problems that causes this unsightly bubbles as the signs of coatings for industrial floors can not address.
Working with the temperature hot or warm
One of the main causes of outbreaks pinhole is hotTemperature. If the concrete surface is heated, vaporized, regardless of moisture in the cracks and crevices defined by the surface. Without an outlet for trapped air, a violent expulsion of air in every part of the publication of weak industrial floor coatings seem to form pinholes.
The solution to avoid air pockets, it is easy to use coatings for industrial floors in hot conditions. The paintings usually work at lower temperatures, when possible, if the cementsurface to be coated is cooler. To do the opposite - install floor coverings industry, when the temperature rises - will catalyze the emergence of pinholes.
From the surface profile
Another cause of micro-holes in the concrete floor is the natural properties of the concrete is rough and irregular. The degree of irregular surface visible in concrete can also vary with the quality of concrete mix. As is often thrown into aggregatesMixture of concrete, is like sand, gravel or slag and ash, not specifically a block of solid material. In reality it is full of tiny, almost invisible holes and irregularities that make them visible for a too rough.
This rough Profile traps more air during the application of industrial floor coatings. For more trapped air will eventually find an outlet if displaced by a film coating, and if the combined air generated enough force to free themselves from the surface, this is the time of the bubblesholes or appear.
The solution to the irregular profile of the surface, is conducting blasting for surface preparation, the uneven surface to reduce as far as possible and facilitate the existence of air bubbles to the surface. Another measure is adopted, the surface is wet with water before the coating effect of moving the air early. There are also concrete epoxy enrichment that can be applied before the coating, which can also move the air through the formation of aCrystal-like seal on the surface of the concrete.
Tame the air displaced
There are also some solutions that work with the behavior of air trapped in participating. One is to reinforce the concrete floor with epoxy sealant that the uneven surface and penetrating the trapped air to be ventilated. When bubbles break through to the outside, the thin epoxy coating that seals the surface.
Another solution is a layered approach, with a quick coating applied for the first timerandom areas of the surface. The trapped air will be taken to look at areas that are not coated. The next layer of coatings for industrial floors will now have a smaller amount of trapped air, reduce the possibility of pinholes.
Another solution to avoid holes, is simply to prevent the trapped air has always been driven into the surface. This is the application of coatings for industrial floors, which are very thick and very airtight seal achieved independently in the air during the coatingApplication.
If care is taken to prevent the formation of holes on the end result of a blister-free system for high-performance coatings business plan is not so difficult to achieve.
