Professional exterior waterproof -k11 universal waterproof coating
In the professional exterior wall waterproof coating, the most common is the k11 general-purpose waterproof coating, which is a kind of two-component waterproof material, combining high-molecular polymer emulsion and inorganic powder and is made of high quality cement. The selected quartz sand is polymerized with a specific polymer to form a waterproof coating on the surface, and penetrates the interior of the material to form a crystal to block the passage of water to achieve a double waterproof effect. It is characterized by a rigid waterproof material that highlights the adhesive properties.
Professional exterior waterproof -JS waterproof coating
JS waterproof coating in professional exterior waterproofing is a kind of green environmental protection material, with the advantages of environmental protection, stable performance, long waterproof life, good aging resistance, convenient construction, simple operation, strong adhesion, etc., JS waterproof coating mostly basic color It is white and has obvious heat reflection function. Compared with the traditional black roof, it can play a better heat insulation effect and can be modulated into color. The roof and exterior wall can be decorated and beautified, and the overall performance is superior. The state has promoted a new type of ideal environment-friendly waterproof material.
Professional exterior waterproof - acrylic waterproof coating
The acrylic exterior waterproof coating in the professional exterior wall waterproofing adopts the international advanced technology and raw materials, and uses the pure acrylic polymer as the base material, and adds the additive to prepare the one-component water-emulsion waterproof coating, which shows the pure liquid state to open the cover. When used, it can be easily combined with the floor gap to form a sturdy waterproof layer. After brushing, it needs to be handled by pulling or sand blasting, thereby increasing its friction and being easy to tiling, and is particularly suitable for use as a wall waterproof material.
Professional exterior waterproof - polyurethane waterproof coating
Polyurethane waterproof coating for professional external wall waterproofing is a kind of internal and external coating, thickness is about 3mm, elasticity is more than 300%, no cracking will be caused on any substrate in use, waterproof effect is excellent, but there are also Inadequacies, polyurethane waterproof coating smell is relatively large, most people find it difficult to accept, need to use the scraper during construction, it is strenuous, the operation is more complex, is a reactive moisture-curing film waterproof coating. Can be used for roofing, exterior walls, non-potable water pools, retaining walls and other waterproof projects.
Professional exterior wall waterproof how to do
Professional exterior wall waterproof first clean the grassroots surface should be compacted and smooth, when the cement mortar leveling layer must be fully cured, there must be no loose, sanding, peeling phenomenon, should meet the design requirements.
Second, blowing dust,
In addition, the key parts are processed
In addition, the bottom brushing
Then, multi-pass waterproof coating
Finally, the coil is bonded
Professional exterior waterproof construction tools:
Motor vehicles, hair dryers, all kinds of roller brushes, washing buckets, paint mixers
Professional exterior wall waterproof construction concrete operation
The first step is to clear the grass-roots level. The old and new surface must be cleaned and free of debris and dust so as not to affect the bond strength. The base layer should be dry when applying waterproof paint. Generally, it can be observed with the naked eye, and can be covered with a 1m square cloth, using sunlight for 1-3 hours.
The second step, after the completion of the grassroots cleanup process, is to clean up the dead ends, which are the so-called yin and yang angles, construction joints, expansion joints and other important parts of the site, especially to pay attention to the drainage hole to strengthen the treatment, you need to brush 2-3 times waterproof primer.
The third step, the preparation of waterproof membrane, waterproof coating, base coating and adhesive coating materials must be clearly identified, in order to improve the adhesion of the waterproofing membrane and the base layer, the primer can be repeatedly brushing, brushing uniform, covering completely Fully infiltrated the concrete base layer to improve the bond strength and shear strength.
In the fourth step, the waterproof coating must be formulated according to the instructions for use of the product. Proportioning is made according to the ratio of A:B=2:1.
The fifth step, the stirring time is about 3-5 minutes, and stir until the mixed liquid of the two parts of A and B is even.
In the sixth step, the uniform waterproof coating shall be applied according to the area to be painted on the site, and the primary coating shall be greater than the area of ​​the adhesive sheet, and shall not exceed thirty minutes.
In the seventh step, before the second coating is applied, the paint must be completely solidified before the second coating is applied. After the first coating, the primer is applied for about 4 to 8 hours before the second coating is applied again. For the third time, the first coating thickness was 0.5mm, the second coating thickness was about 0.5mm, and the third coating thickness was about 0.5mm.
In the eighth step, it is necessary to wait for the second coating to completely solidify before bonding the coil.
Editor's summary: The above is the professional exterior wall waterproof coating and construction specific operation window seepage water to find out the reason is the key related introduction, hope to help to have this kind of demand friend!
