Melbourne has variable weather. Even on a single day, one may experience sun, rain, and cold weather. This type of climate is severe for floors, particularly in garages, warehouses, and workshops. Vinyl flake floors are preferred by many property owners since they are good-looking and durable. However, there is one very crucial step that determines whether the floor will be long-lived or not. Preparation is that step. During wet weather in Melbourne, proper floor preparation is not a choice. This article reveals why preparation is so critical in Melbourne, the consequences of having poor preparation and how to do the job right.
How Melbourne's Climate Affects Floors
The weather conditions in Melbourne pose special challenges to concrete floors. Soil beneath a structure remains moist most of the year. This water is not retained in the ground. It travels through the concrete slab upwards. This process can be used to understand why the floors made out of vinyl flakes require special care in this city.
High Rainfall and Humidity
The quantity of rainfall received in Melbourne is good. The mean annual precipitation is approximately 650mm. This rain enters the ground surrounding the food, new structures and below them. The moisture of the air also remains high over a good number of months. Humidity is high, which causes an increase in the amount of water vapour in the air. This vapour may be deposited on concrete. In case a floor coating is laid on wet concrete, the moisture becomes trapped underneath. With time, this confined water acts upon the coating, pushing it downwards. The effect is a floor that lifts, bubbles or peels off the concrete.
Moisture Rising Through Concrete
Concrete is a porous substance. It has small holes and crevices within it. Water in the wet soil below a building is drained through these small holes. This is referred to as moisture vapour transmission. Although the surface of the concrete may be dry to the touch, the water may be rising beneath. This is very prevalent in Melbourne since the water table is usually elevated and also the soil remains wet. This increasing moisture will not be detected in a simple surface test. To determine the amount of moisture percolating through the slab, special equipment is required.
Why Floors Fail in Wet Conditions
When water comes in contact with floor coating, various issues may begin. The coating is similar to the plastic sheet on the concrete. When this sheet becomes damp, it puts pressure on. The coating is not breathable and hence, there is no outlet for the moisture. This pressure will result in the breaking of the bond between the coating and the concrete. The coating begins to peel off as soon as the bond is broken. When it is wet, it can start in weeks or months rather than years. This is one of the reasons why floors that perform well in arid climates will perform poorly in Melbourne.
What Happens When Prep Is Poor
The primary cause of failure of the vinyl flake floors in wet areas is poor floor preparation. In cases where an installer is careless or in a hurry, the outcomes are readily noticeable. Such issues are not only aesthetically displeasing but may also prove to be costly to repair.
Flaking and Peeling
The most common problem is flaking. Small pieces of the coating lift away from the concrete surface. These pieces look like paint chips or flakes. Over time, more pieces come up. The floor starts to look patchy and worn. Peeling is a more serious version of flaking. Large sections of the coating lift away completely. You can pull up the coating with your fingers. This happens because moisture has broken the bond between the concrete and the coating. Once peeling starts, the entire floor may need to be removed and replaced.
Bubbles Under the Surface
Bubbling is another indication of poor preparation. The surface of the floor has small bubbles or blisters. These air bubbles are spaces of stagnant water. As you step on them, they can be soft or spongy. Other bubbles are small such as pimples. Others can be as large as a coin or bigger. The presence of bubbles is an indication that there is moisture on the rise. The bubbles do not pop immediately, but weaken the floor. The bubbles then expand and the coating ruptures with time.
Mold and Smells
Wet conditions combined with poor preparation can lead to mold. Moisture trapped under the floor creates a dark, damp space where mold grows. You may not see the mold because it is under the coating. But you will smell it. A musty, earthy smell often comes from mold growing under a failed floor. This smell can fill a garage or a room. Mold is also bad for health. It can cause allergies, breathing problems, and headaches. Once mold grows under a floor, the only fix is to remove everything and start again.
The Right Prep Steps for Vinyl Flake Floors
Good preparation for flake flooring follows a clear set of steps. To begin with, the concrete needs to be tested in terms of moisture. By just putting a piece of plastic taped to the floor, one can tell whether the moisture is increasing or not. Improved tests are performed with an exclusive meter that detects the amount of moisture in the concrete. Second, cleaning of the surface is required. The dirt, oil, grease, old paint should be eliminated. Third, the surface is ground or shotblasted. This action is done to expose the pores of the concrete in order to allow the coating to adhere. Fourth, any cracks or holes are filled with a repair compound. Fifth, a primer is placed. The primer makes the concrete waterproof. Sixth, the flake coating (vinyl) is made in layers. The layers should be allowed to completely dry before they are covered by the next layer. Seventh, a top coating is applied to cover the flakes and cover surface. Any of these steps should not be overlooked, as it is very dangerous, particularly in the wet climate of Melbourne.
Tools and Materials for Good Prep
To prepare a floor properly for flake flooring in Melbourne projects, installers need the right tools. A moisture meter is the most important tool. It measures the moisture level inside the concrete. A floor grinder or shotblaster is needed to open the concrete pores. Industrial vacuums keep the surface clean during grinding. Diamond grinding wheels or discs are used for the actual grinding. For repairs, epoxy patching compound fills cracks and holes. A primer designed for damp concrete is essential. Rollers and squeegees help apply the primer and coating evenly. Good lighting helps the installer see low spots or missed areas. Without these tools, proper preparation is almost impossible.
Questions to Ask Your Installer
Before hiring someone to install a vinyl flake floor, ask these questions. Did you test the concrete for moisture? What were the results? Do you use a grinder or shotblaster to open the concrete pores? What brand of primer do you use for damp concrete? How many layers of coating do you apply? What is your warranty if the floor peels or bubbles? A good installer will answer these questions clearly. They will also show you examples of past work. Be careful with installers who say preparation is not needed or who rush the job. The epoxy flake flooring Cost may be higher for a job with good preparation. But paying more upfront is cheaper than replacing a failed floor after one or two years.
Conclusion
Due to the wet conditions of Melbourne, preparation of the floor is very crucial. Rain, moisture, and humidity of concrete increase through the concrete, which can ruin a floor coating within a short period of time. Flaking, peeling, bubbling, and mold are the result of poor preparation. These issues are costly to repair. The correct preparation steps are time-consuming and require the right tools. They are the sole method of ensuring a vinyl flake floor lasts. In selecting an installer, you need to ask the appropriate questions and seek an individual who is serious about preparation. When a floor is prepared properly, it will remain strong and be attractive over a long period, despite the harsh climate in Melbourne.
