Many waterproof coating constructions have certain requirements for the thickness. To detect these film thicknesses, it is naturally inseparable from the paint thickness gauge.

1. What are the thickness requirements for waterproof coating construction?

Normally, the waterproof coating thickness is about 1.5MM. But in some special places, it is best to paint each time separately and pay attention not to exceed 1MM. Especially like corners, pipe openings, or uneven base surfaces. These are the key places for waterproof construction. In addition, different coefficients are generated after thermal expansion and contraction, which may cause cracks to appear and even cause local water seepage.

There are about two types of waterproof coatings currently available on the market, one is polymer cement-based waterproof coating. The other is polyurethane waterproof coating. The former is more environmentally friendly, is a non-toxic and harmless environmentally friendly product. The operation is simple and convenient, which helps the construction staff to improve work efficiency, thereby reducing the upfront cost. The latter is different. It is made of asphalt as a raw material. It contains a large amount of organic solvents. These organic solvents are toxic and harmful and they are very environmentally friendly to use. Now people's environmental awareness is becoming stronger and stronger. Non-toxic and harmless environmentally friendly waterproof materials are more popular in the market.

2. Tips for using paint thickness gauge

The waterproof coating thickness has such strict requirements, so what problems should we pay attention to when using the paint thickness gauge? When many people use the paint thickness gauge, the data detected twice before and after are different and even the error is very large. In this case, some people will question whether the paint thickness gauge is not accurate enough. In fact, the paint thickness gauge is not used correctly, so such a large error will occur. As long as you know how to use the paint thickness gauge, you can accurately detect the waterproof coating thickness.

First of all, when using the paint thickness gauge, pay attention to keeping the instrument and the probe stable and do not shake the paint thickness gauge violently. Strong vibration will cause inaccurate measurement results. Secondly, the difference in environment will also affect the accuracy of the measurement. It is best to use it in a dry and ventilated environment. The daily maintenance of the paint thickness gauge is also very important. Wipe the paint thickness gauge regularly to keep the instrument clean and dust-free. The dust and dirt on the paint thickness gauge will also accelerate the aging of the probe line. If there is oil stains attached to it, it will be more serious. And it may cause the probe line to break, so you must clean the paint thickness gauge every time you use it, so as to prolong the service life of the measuring instrument. In addition, the battery selection of the paint thickness gauge is also very important. Never use inferior batteries in order to save money. The use of inferior batteries may cause leakage of the instrument. In serious cases, it may even cause the host to be scrapped directly. If we do not use the paint thickness gauge for a long time, we must remember to remove the battery to avoid accidents.
