What should I do with K11 waterproof coating for roof waterproofing?

K11 looks simple construction, but the details are very important, so as to ensure the quality of construction, you must first rinse the roof base with water and brush clean, because it is generally divided into two coatings, so the mixing material should also be divided into two mixing, "special attention should be paid to the mixed material must be used up at one time." "Mix the liquid powder in proportion, and stir evenly without particles, let it stand for a few minutes, and then stir it, the base surface is moist and there is no clear water, you can brush it, stir it from time to time, in case the powder sinks to the bottom, it must be brushed in place, can not miss the brush, and wait for the first time to dry without sticking to your hands, and then carry out the second coating.

Can K11 be roofed? It must be done to do the type 1 national standard, the 11 type and 111 type national standard can not be done, and it can't be kept for a long time, but it must be a protective layer! If you don't do a protective layer, you won't be able to keep it for a long time.

With a blender, stir well, and then brush it, no special tricks. Brush the seams a few more times, wish.

Master flexible waterproof coating.

Laofu flexible waterproof coating is a two-component, acrylic high polymer modified cement-based waterproof material. It consists of high-quality aggregates and powders of selected additives as well as liquid polymer.

After the powder is mixed with the additives, a chemical reaction occurs to form a tough 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.

Construction method. 1. Slowly pour the powder into the liquid and stir continuously until it is stirred into a uniform paste without small particles and bubbles, and then it can be used.

2. Use a brush or roller brush to directly apply the mortar on the base surface, do not miss the brush, in order to prevent precipitation, intermittent stirring should be maintained during the operation.

4. Generally, the coating should be brushed more than twice (the direction of each coating should be staggered), and the final coating film thickness should be kept at 1-2kg m2.

5. At the same time of painting, the corner joints and cracks are reinforced with non-woven fabric or glass fiber to enhance the crack and tensile resistance, and the waterproof membrane must be coated when the tile is directly pasted.

The surface makes the waterproofing membrane completely cover the substrate to achieve the waterproofing effect.

Base surface treatment. 1. The surface must be flat, solid, clean, free of oil, dust and other loose animals.

2. Obvious voids and sand holes should be plugged and smoothed with cement mortar, and sharp edges should be removed.

3. Pre-moisten the substrate until there is no stagnant water.

4. The newly poured concrete should have a certain dry curing time to prevent the impact of concrete shrinkage.

5. The old concrete surface must be rinsed with clean water first, dried and then painted.

K11 waterproof coating

K11 waterproof coating is a unique, very active polymer powder and synthetic rubber, synthetic phenylenene grin and other emulsion blends, adding binders and appropriate amounts of chemical additives and fillers, through plasticizing, mixing, calendering and other processes to process the polymer waterproof materials, the selection of imported materials and domestic high-quality auxiliary materials, in accordance with the national industry standards of the highest level of instructions to produce high-quality products, listed as the Ministry of Construction of the key promotion products.

Second, K11 waterproof advantages

1.The active ingredient in the slurry can penetrate into the capillary pores in the cement substrate, micro-cracks and produce chemical reactions, and penetrate into the crystallization inside the substrate to form a dense waterproof layer;

2.Able to cover hair-like cracks (less than mm), resist and slight **;

3.It can be applied on a wet base surface, and can be directly pasted with ceramic tiles and other follow-up processes without a mortar protective layer;

4.The crystal penetrates deep into the capillary pores of the substrate, has high impermeability and compressive strength, and has the waterproof function of negative water surface.

5.Non-toxic, harmless, can be directly used in drinking pools and fish ponds; The coating has the effect of suppressing the growth of mold and prevents the contamination of the finish by moisture salts.

3. K11 waterproof coating operation method

1.Method 1: We can directly pour the powder into the matching emulsion, but the pouring should be slow, and in the process of pouring, we should pour it like an oak and stir it with an electric mixer, so that it can be fully stirred, and under normal circumstances, stir for three to five minutes to see that there is no dough, and it becomes a uniform slurry.

After that, we need to let it sit for 10 minutes, and then go back to the section for 2 minutes of stirring. When we stir for the second time, we should pay attention to the fact that the agitator should touch the bottom of the container, and do not lift up and let the air roll in, and then we can use the adjusted paint within an hour.

2.Method 2: When we encounter a relatively large gap when we paint, we can choose a glass fiber mesh cloth for reinforcement.

If it belongs to the kind of prefabricated assembly joint or deformation joint, then we had better lay a layer of non-woven fabric strip or plastic film on it along the crack, and then we will carry out the painting operation on it, and the scope of the painting should be linked with the periphery of the painting, so that the K11 waterproof coating can fully show its ductility, and can also prevent the anti-coating film from being pulled apart due to the deformation of the base surface.

3.Method 3: Choose a brown brush and then paint evenly on the base surface, we choose the base surface to choose the kind of moist but no obvious water, we should pay attention to avoid brush leakage when brushing, we see that a layer of coating has been cured and has a certain strength, we will carry out the construction of the next layer, guide the last layer, but the last layer in the construction of we had better choose the wool brush, so that we can ensure that the surface is more smooth.

If there is still a decorative layer on the surface of our base surface that needs to be constructed, then it is best for us to choose a brown brush and then carry out transverse wire drawing treatment in the last layer, so that the adhesion will be better, and the painting direction of each layer should be selected to cross each other vertically for painting.

Modern decoration will use a variety of materials, but in the decoration process waterproof is still particularly important, the current market stupid chain of waterproof coating brands are still a lot, of which K11 waterproof coating is one of them. Let's introduce to you what is the construction method of K11 waterproof coating.

1. Leveling and cleaning the ground, making the yin and yang corners into arc angles, smoothing the sharp places, and maintaining the roughness of the base surface of the wall tiles, and doing a good job of brushing the wall if it is too smooth.

2. Wet the ground with water, and for corners, wall pipes, construction joints and other places, you can use waterproof coating and glass fiber cloth to strengthen the treatment, and the thickness is in.

3. For the waterproof layer, it is necessary to water and moisten the surface, maintain a certain humidity in the blind state, and then brush the stirred waterproof coating directly on the base surface in proportion, press and brush several times, the first layer is not sticky and then directly brush the second layer, the general waterproof needs to brush more than two layers, and the last waterproof layer is not dry when the sand is sprinkled on it, so that it can enhance and protect the adhesive belt of the tile bonding layer.

4. After the waterproof layer is dry, you can make a thick cement mortar protective layer or a tile and other finishing layer according to your needs.

What are the main features of K11 composite waterproof coating.

1. It can be directly constructed on the base surface of a variety of materials in wet or dry;

2. The coating is tough and high-strength, with excellent water resistance, weather resistance and durability;

3. Pigments can be added to form a color coating; Odorless, pollution-free, simple construction and short construction period; The construction on the façade, slope and top surface does not flow;

4. It is firmly bonded to the base surface of various materials such as cement mortar.

Summary: What is the relevant content of the K11 waterproof coating construction method is introduced here, we must follow the method to carry out the construction, and some details should also be paid special attention to, can not be treated sloppily, so as to achieve the effect you want, if you want to know more about relevant knowledge, you can **** Qijia Home to consult.
