What waterproofing paint is used for underfloor heating? What waterproof material is used for floor

General floor heating, we don't know what kind of waterproof material to use, let me briefly introduce it below. Materials used for underfloor heating.

1 Oqi K11 flexible waterproof coating.

It is a two-component, acrylic acid.

Improved cementitious waterproofing system with high polymer type. Its powder is made of high-quality cement and selected quartz sand.

and other materials, and the liquid material is a special modified acrylic polymer latex. After mixing its powder with liquid material in proportion, a chemical reaction occurs.

It forms a tough and elastic waterproofing membrane that adheres well to concrete and mortar and forms a tight, strong and permanent bond with it, preventing water from penetrating.

Features: 1.It has good flexibility.

It can resist the slight vibration of the building and the micro-cracks caused by various reasons;

2.Able to work on several wet surfaces;

3.Strong adhesion to the substrate, not only can have good adhesion to the substrate, but also can be directly plastered, leveled, and pasted on the waterproof plaster;

4.It can be applied to humid environment, with good weather resistance and corrosion resistance;

5.Easy construction, short curing time and fast drying;

6.It is breathable and can keep the base surface dry;

7. Environmental protection, non-toxic, tasteless and pollution-free.

2. Floor heating in the bathroom can be waterproofed by Yuhong 300 self-healing waterproof coating. Yuhong 300 self-healing waterproof coating is a two-component functional water-based water-based waterproof coating, its powder is made of high-quality cement, selected quartz sand and other materials, and the liquid material is a highly environmentally friendly modified polymer emulsion. After mixing the powder with the liquid in proportion, a chemical reaction occurs to form a tough and elastic waterproof membrane, which has good adhesion to concrete and mortar, and can form a tight and firm permanent bond with it, preventing the penetration of water.

Nowadays, many homes have begun to install floor heating, but they do not know much about the choice of floor heating waterproof materials. In fact, the installation of floor heating is generally divided into electric heating and plumbing, but the materials of floor heating waterproofing are generally recommended to use mortar waterproofing agent to do waterproofing, because mortar waterproofing agent can make the base surface bonding more firm, puncture resistant, and high strength, waterproof life is longer, on the other hand, the use of mortar waterproofing agent, the construction is relatively simple, can withstand high temperature, and can fully meet the requirements of waterproofing.

1. The installation of floor heating must be waterproof, the purpose is to leak with waterproof pipes, resulting in problems such as water leakage downstairs. If you have the strength, you can choose to do waterproofing twice, which is the most reliable way, one layer above, one layer below, double layer protection. If the conditions are limited, just one layer is fine.

After the water is discharged, you must do a closed water test to test whether it is qualified.

2. After the installation of floor heating, the pressure test should be suppressed, each room has a pressure gauge, and the test can be backfilled only after passing the test.

3. If there is no waterproofing before laying floor heating, the cause of leakage may be a problem with floor heating or a problem with domestic water pipes, that is to say, the cause of water leakage can be quickly found, so as to avoid the phenomenon of shirking responsibility between the owner and the floor heating installation unit.

4. We all know that even if the developer has done waterproofing during the construction of the rough house, the quality may not have passed, because it cannot guarantee that all developers will do their work honestly, and they can save a lot of money by doing their hands and feet, so it is recommended to do waterproofing again when decorating.

Generally, the bathroom is waterproof, made of flexible waterproof mortar, which is more convenient for construction, environmentally friendly and pollution-free. If the house is handed over to the house, there is a bathroom with floor heating, and you can do waterproofing directly on the bathroom floor and wall. If there is no floor heating in the house, do it yourself, for safety, you can do it again before doing floor heating on the bathroom floor and after doing floor heating.

Bathroom waterproofing is generally done above the floor heating layer and below the cement mortar brick layer.

**，。The polypropylene cloth is waterproof.

Polypropylene cloth waterproofing is mostly used indoors, is membrane waterproofing, after leveling the bathroom wall and ground, directly laid, laid with cement mixture adhesive, this material is relatively stable, and the bond with cement mortar is better. It is generally used for indoor waterproof construction with a relatively large area. The indoor toilet area is relatively small, and it can be used if it is a project developer.

I use less for my own decoration.

**，。Polyurethane waterproof.

The advantages of polyurethane waterproofing are good weather resistance, good waterproof performance, strong ability to adapt to the base layer, and good hiding power and toughness for the deformation of the base layer. Tar or asphalt is commonly used as an additive, and developers often use this to make toilet waterproofing, which is easy to construct and has good weather resistance, but the smell of asphalt is relatively large. It is used more in the field of building construction, such as basement waterproofing and building bathroom waterproofing.

**，。Flexible waterproofing mortar.

Flexible waterproof mortar is a commonly used waterproof construction method for home decoration, which is only used for indoor waterproof mortar. The construction is more convenient. It is a commonly used waterproof method for interior decoration. Good weather resistance, covering the fine cracks of the base layer.

There are fewer cases of floor heating leakage, generally in the bathroom with floor heating, waterproof is done on top of the floor heating layer.

OK. The two waterproofing before and after floor heating are actually different. The waterproofing layer that is done before the floor heating is done is to prevent the leakage of the floor heating water pipe from seeping into the downstairs neighbors, and the waterproof layer is made after the floor heating is laid, so that the water pipe of the family will not leak into the floor heating and affect the water pipe of the floor heating.

In particular, some families will install floor heating in the kitchen and bathroom, balcony, if these spaces have to do floor heating, it is necessary to do two layers of waterproofing, if it is the living room, the bedroom and other places that do not use water, some people will choose to do only one layer of waterproofing. Only do the upper waterproofing layer after the installation of floor heating, but not the lower waterproofing layer after the installation of floor heating.

OK. The order from bottom to top is as follows: waterproofing - underfloor heating insulation board --- underfloor heating pipe--- aluminum foil mulch film - protective layer - waterproofing - backfilling cement --- floor or floor tiles.

Now it is generally required to do two times of waterproofing, and after the floor heating is laid, do waterproofing again on its protective layer, in fact, this waterproofing is also equal to doing it in vain, because the existing waterproof materials can not withstand the test of high temperature for a long time, the cement protective layer will eventually crack, and the waterproof layer will fail sooner or later.

Therefore, it is the key to do a good job in the waterproofing of the original ground under the floor heating insulation layer and the waterproofing of the threshold part.

Yes, the landlord floor heating is not done.

The order from bottom to top is as follows: waterproofing - underfloor heating insulation panels--- underfloor heating pipes--- aluminum foil mulch--- backfilling cement --- floors or floor tiles.

It is recommended to do the following, and there is too much uncertainty in doing it above.

With the continuous development and change of technology, there are more and more heating methods nowadays, and underfloor heating is one of the most popular, because this method takes up the least space. So, does the floor heating need to be waterproof? What do you need to pay attention to when installing underfloor heating?

Let's take you to find out.

Underfloor heating needs to be waterproofed, because this can prevent water pipes from leaking, so as not to cause unnecessary trouble to the downstairs neighbors. If your own conditions allow, you can do two times of waterproofing, and make a layer of waterproof above and below the floor heating, but if the conditions are limited, then do a layer of waterproofing on it, that is, wait until the floor heating installation is completed and then do a layer of waterproofing.

Precautions for underfloor heating installation.

1. The installation of floor heating must find a construction team with professional knowledge of floor heating. If you are looking for an amateur decoration team to install, the effect of paving is self-evident. Floor heating must be checked before paving the tightness of the system, the ground needs to be kept dry, and the moisture content of the cement floor is best lower, and the indoor humidity in the construction process can not be too large, regardless of whether there is geothermal heating, the ambient humidity before and after installation must be about 60 degrees.

2. During the construction of floor heating, the ground cannot be nailed, and after the construction is completed, the ground is also forbidden to nail, because the ground will destroy the heating coil if it is nailed. In addition, before laying the laminate floor, it is necessary to lay EPE composite film, which can isolate the moisture, so that the moisture can be released from the surrounding skirting boards, and it is necessary to remember that the keel can not be laid, so that the thermal conductivity of the air will become smaller, affecting the heat dissipation effect of floor heating, and it may also damage the pipe.

Article summary: The above is all about whether floor heating needs to be waterproof and what needs to be paid attention to in floor heating installation, I hope it will help you. If you want to know more about it, please stay tuned to Qeeka Home.

First, the ground to be laid geothermal is treated, keep the ground tidy, dry and flat, and then brush a layer of waterproof paint, which can prevent the leakage of geothermal pipes from seeping into the downstairs, and the insulation layer can be laid after the paint is dry to avoid the smell of the waterproof membrane when heated, and then you can lay the geothermal pipe, and then lay a layer of EPE composite film on the surface to isolate the moisture, and finally lay the floor.

Waterproofing is mainly done in bathrooms, kitchens, balconies, waterproofing has nothing to do with installing floor heating, floor heating is mainly in the living room, bedroom, these places do not need to do waterproofing.

Installing floor heating is to be waterproof, if the floor heating leaks, it will cause great losses downstairs, and these losses are borne by the upstairs. Unlike toilets, if the waterproofing is not done well, the loss is not particularly large, but the large coverage area of the floor heating may damage some ** value property, so it is quite necessary to do waterproofing.

What should be paid attention to in the installation of floor heating 1, the floor heating pipe laid under the ground is only about 3-4cm away from the floor surface, smashing and knocking on the ground is easy to hurt the floor heating pipe, so it is strictly forbidden to smash and impact the ground heating pipe, and it is strictly forbidden to wedge sharp objects such as nails on the ground to avoid damaging the ground pipe. Especially in the process of house decoration, it should be avoided that the workers who cut the tiles will cut the floor heating pipe and damage the spring shirt.

2. When placing scaffolding and other tools on the floor heating system, protective measures such as laying wooden boards to increase the stressed area must be taken to avoid damage to the floor heating system.

3. When the downstairs user of the floor heating user really needs to drill holes on the roof, it is necessary to pay attention to the drilling depth can not exceed the thickness of the floor structure to prevent damage to the upper floor heating pipe.

4. It is strictly forbidden to place a high-temperature heat source near the water collector and on the ground where the floor heating pipe is laid to prevent damage to the pipeline system.

5. When there is no heating in winter, attention should be paid to protection to prevent the spike cracking of the water separator parts and the freezing of the water in the heating pipe from blocking the pipe.

What to pay attention to in geothermal construction 1. Pay attention to geothermal materials.

Geothermal energy belongs to the concealed engineering, the geothermal material is not selected, if there is a quality problem or a short service life, it is very affecting the use, and it will cause a very large loss, so the geothermal material should be tested before construction, and the surface of the high-quality floor heating pipe is smooth and not concave, there are no bubbles and obvious color difference, and the degree of softness and hardness is moderate.

2. Pay attention to field measurements.

Before geothermal construction, it is necessary to find a professional installation company for on-site measurement, because not every home and any functional area is suitable for installing floor heating, if it is installed in an unsuitable place, it is easy to have problems, and usually this kind of place needs a more reasonable design scheme.

3. Pay attention to the coil.

Geothermal energy must be strictly cautious in the construction, the coil should pay attention to the distribution interval, the bend can not be folded, in order to ensure the uniformity and stability of heat dissipation, during the construction should also be checked at any time to check the air tightness of the system, can not ignore the water injection pressure inspection.
