K 1 1 waterproof coating is a two-component polymer molecule modified polymer waterproof system. It is a two-component polymer molecule modified polymer waterproof system. There are unique and very active polymers.
An emulsion mixture consisting of polymer powder, synthetic rubber and synthetic fat. And basic materials, and appropriate chemical additives and fillers are added.
, polymer waterproof material by plasticizing, mixing, calendering and other processes, using imported materials and domestic high-quality accessories, according to
The high-quality products produced by the highest-level instructions of national industry standards are listed as the key promotion products of the Ministry of Construction.
Outstanding features:
It can be constructed on wet and dry foundations, with long service life, weather resistance, aging resistance, oil stain resistance and certain acid resistance.
Excellent performance, waterproof, non-toxic, tasteless, pollution-free, safe and simple construction, short construction period and so on. It is an ideal waterproof material of 1 grade.
Scope of adaptation:
Various industrial and civil buildings, bathrooms, kitchens, roofs, gutters, balconies, external walls, basements, pools and sewers.
Waterproof, moistureproof and anticorrosion works for roads, mines, tunnels, bridges and pouring expansion joints. Smear with tiles, cracks in external walls
Plug the leaking gap.
Construction method:
After the powder is mixed with the emulsion, it reacts chemically, permeates into the pores inside the matrix, and is integrated with the matrix.
A layer of crystal clear and dense waterproof layer closes the passage and penetration of water to achieve waterproof effect, and each layer should be crisscrossed and repeated.
The time interval between layers shall be subject to the previous layer not touching hands, and the previous layer shall be dried before scraping the next layer, flashing, expansion joints and eaves gutter.
Where it is extremely important or needs special treatment, the matrix can be added for reinforcement, and the waterproof layer can be used as a protective layer or other covering layer after completion.
JS waterproof coating is a green waterproof mortar coating with the latest special formula in Germany. Good technical performance and outstanding waterproof effect, recommended by the Ministry of Construction. This material is a two-component waterproof coating composed of organic liquid and inorganic powder. It is an environment-friendly waterproof material with high elasticity of organic materials and good durability of inorganic materials. The coating can form a high-strength and tough waterproof coating film.
2. Main features
1) can be directly used for construction on wet or dry base surfaces of various materials;
2) The coating is tough, high in strength and excellent in water resistance, weather resistance and durability;
3) adding pigment to form a color coating;
4) non-toxic, tasteless, pollution-free, simple in construction and short in construction period;
5) Facade, slope and top surface construction will not flow;
6) It is firmly bonded to the base surface of various materials such as cement mortar.
Second, the product application scope
Type I and type II (liquid: powder 1: 1) Ginzh "JS waterproof coating" can be directly coated on wet or dry masonry, mortar, concrete, metal, wood, hard plastic, glass, various insulation layers and various waterproof layers. Can be used for new and old buildings and structures (such as roofs, basements, bathrooms, external walls, tunnels, bridges, pools, reservoirs, etc.). ). At the same time, "JS waterproof coating" is mixed into putty according to the ratio of liquid: powder = 10: 25-30, which can be used as adhesive sealing material.
JS-I waterproof coating is a waterproof project specially used in non-long-term immersion environment.
JS-II waterproof coating is specialized in waterproof engineering under long-term immersion environment.
Third, the construction technology
1. Base surface treatment: the base surface must be flat, firm, clean, free of dew, leakage, unevenness and cracks, and the leakage must be leveled first (it is recommended to use "watertight" produced by our company for base surface treatment), and the angle of yin and yang should be smooth.
2. Ingredients: If water is needed, first add water to the mainland material, slowly add powder while stirring with a stirrer, and then fully stir until the material contains no particles (stirring time is about 5 minutes, preferably without manual stirring).
Proportion of primer coating: liquid: powder: water = 10: 10: 14.
Proportion of other coatings: liquid: powder: water =10:10:1-2.
The pigment content of color paint is below 10% of the powder quality, and the water content should be within the specified range, and it should be constructed on the inclined plane, top surface or facade. In order to hang enough paint, without adding or adding less, more water can be added for flat coating in plane construction.
3. Selection of construction method: According to different waterproof projects, one of JS-I or JS-II waterproof coatings is generally selected for construction. One of P3, P4 and P5 can be selected for each coating. JS-I is suitable for waterproof projects (such as roofs) that are not immersed in water for a long time and the matrix is easy to deform.
JS-II is used in waterproof engineering with long-term immersion environment and small matrix deformation.
The coating structure, application scope, required auxiliary materials and coating dosage of the three construction methods are shown in the following figure.
4. Coating color: The natural colors of Kwang "JSJSJS waterproof coatings (Type I and Type II) are gray and milky white, and coatings of various colors can be made by adding pigments accounting for 5%- 10% of the powder weight. Pigments should be neutral inorganic pigments (iron oxide series is recommended), and other pigments can only be used after being confirmed by tests.
5. Coating: coating with roller or brush, and finishing layer by layer according to the selected works. The time interval between layers shall be based on the previous layer being dry and non-sticky. P5 construction method, the lower layer, strengthening layer and middle layer must be constructed continuously and cannot be separated. The reinforcing layer should be laid straight, and the following matters should be paid attention to when coating:
1) If the paint (especially the primer) is precipitated, stir it evenly at any time. When dipping, stir at the bottom of the barrel a few times to avoid precipitation.
2) The coating should be as uniform as possible, without local deposition, and it should be rolled several times, so that there is no bubble between the coating and the base, and the bonding should be sealed.
3) Each coating must be taken in accordance with the prescribed dosage, neither too thick nor too thin. If the waterproof layer is not thick enough, you can add one or more layers.
4) The reinforcement layer can be made of 50 g /㎡- 100 g/㎡ polyester long fiber non-woven fabric or high-quality glass fiber grid cloth.
Four. Sampling method of product quality before use
Before use, samples should be taken from the site by machine, with a total weight of not less than 2 kg. The inspection shall be conducted according to JC/T894—200 1 standard.
5. Quality requirements and engineering inspection
After the construction, we should carefully check all parts of the whole project, especially the weak links, find out the reasons and repair them in time. After coating waterproof mortar layer, there should be no accumulation, cracking, peeling, flowing, bubbling, wrinkled skin, warping and other phenomena. Thickness should meet the design requirements. The water storage test can only be carried out after the coating is completely dried. It usually takes more than 48 hours, and it takes longer in a particularly humid and unventilated environment.
Matters needing attention in packaging, storage and use of intransitive verbs
Liquid materials are packed in 5 kg and 20 kg barrels; The powder is packed in 20kg bags, 5kg× 4 pieces per box, and stored in a cool, ventilated and dry place above 5℃. The shelf life of liquid and powder is 12 months.
It is not allowed to construct under 0℃ or in the rain, nor is it suitable for construction in a particularly humid and unventilated environment, otherwise the film formation will be affected.
Special recommendation: JS waterproof coating combined with "water tightness" can achieve fast and flexible plugging effect.
