Exterior wall cleaning and exterior wall coating construction scheme?

1. Waterproofing and leakage-patching of high-rise wall: The wall is a vertical component of the building, but factors such as design, construction, materials and use will cause cracks in the wall and lead to leakage.

Anti-leakage method of wall: the original structure waterproof is repaired by linear structure waterproof, which is used to disperse water.

When the cavity structure is damaged locally, it is best to use restorative repair.

Repair with waterproof materials: This method has a wide range of applications, that is, when rainwater penetrates into the room, it is filled with oil-soluble or water-emulsion waterproof materials or painted.

Waterproof measures should be taken on the outside of the external wall panel.

Water blocking method of exterior wall coating: waterproof measures are taken at the inner half of exterior wall to prevent rainwater from invading through waterproof materials.

Our company's construction force is aerial work, and professional and technical personnel carry out investigation, demolition and formulation of construction plans for various waterproof restoration projects. Therefore, there is no need to set scaffolding for waterproofing and plugging of high-rise external walls, saving auxiliary costs.

Second, the construction of exterior wall coating: the construction of new wall coating: the bottom layer of building exterior wall coating requires sufficient curing period, and the surface of fresh water mortar concrete must be cured for a reasonable time to make it "spit alkali" and fully dry. The bottom surface should be dry, solid and firm, and there should be no defects such as sand, cracks and looseness.

Construction method: Exterior wall painting should not be plastered with putty in a large area, and the putty layer should not be too thick. The material is polymer cement putty. Generally, primary coating and secondary surface coating are adopted. According to the requirements of engineering quality, the number of surface painting can be increased appropriately. Painting construction is generally carried out from top to bottom, and each painting should be bounded by dividing line, wall surface, junction of yin and yang angle or downpipe.

Operating tools: generally, roll coating, brush coating or gas spraying and airless spraying are adopted.

Maintenance and renovation: the biggest advantage of decorating the building surface with paint is that it can be renovated within a certain period of time, and the building is generally fully repaired once every 4-5 years. Make a comprehensive investigation before exterior wall decoration and make a construction plan.

After the painting project is completed, we will conduct long-term quality tracking and return visit to our customers, and provide a painting maintenance plan.

Third, the glass maintenance of the building curtain wall: the glass curtain wall is used for exterior wall decoration, and the quality is difficult, so the process requirements are strict, and the engineering quality must be guaranteed.

After years of practice, the curtain wall glass maintenance project must form a set of scientific technological processes and supporting installation procedures. Installation and use of structural glue and weather-resistant glue in sealant (imported glue should be used), with smooth gluing, clear lines and no leakage. The selection of curtain wall glass is strictly in accordance with the design requirements.

4. Cleaning of central air-conditioning equipment: Neutral cleaning agent is used to clean central air-conditioning units and fan coils, which is harmless to human body and has no corrosion damage to equipment.

It is stipulated that the process of direct spray cleaning should not be disassembled. It can quickly penetrate, dissolve and take away the dust and grease on the heat sink, significantly improve the refrigeration effect, sterilize and deodorize, and have no pollution to the environment.

Five, the installation and removal of high-level advertising

For medium-sized and above advertising buildings, designated safety technicians shall survey the project site, formulate the project construction plan, delimit the safety area, equip the project hoisting equipment and dispatch construction personnel.

Six, high-rise pipeline installation and maintenance

Hoisting personnel shall operate according to routine safety regulations. On the ground and on the top floor, full-time personnel shall coordinate, command and operate, and designate safe areas.

Seven, paint-wood finish, metal finish, gypsum finish.

Select high-quality paint and reasonable construction technology to ensure the engineering quality. Whether it is new or redone, the base surface needs to be treated, and the joints and concave and convex points should be leveled.

Eight, solid wood floor renovation

Polishing for several times with a large floor turnover machine, removing the paint layer, surface layer and wood layer by about 0.4-0.6 mm, and then polishing carefully to make the floor surface fine and the gloss reach the new standard. The edge of the floor should be polished with a cross grinder to achieve the overall effect, then re-sealed, and finally painted or waxed according to customer requirements.

Nine, marble, granite, terrazzo renovation

According to the wear degree of stone surface, it can be divided into three types: mild renovation, shallow renovation and deep renovation.

Slight transformation: generally, there is no need to use a special weighting machine, and the operation is relatively simple. Generally, sand and dust particles on the ground are removed, stains are washed and waxed, and polished for many times with special machinery until the reflective effect is achieved. After all renovation procedures are completed, the crystal is hardened.

Shallow decoration: the stone floor is seriously worn, but the scar is less than 0.5 mm A weighting machine can be used and operated under the guidance of a decoration technician.

Deep renovation: the stone surface has been in disrepair for a long time, and the damage is very serious. The depth of surface scar is greater than 0.5mm, and the construction scheme shall be drawn up after on-site investigation by full-time personnel.

Ten, marble, floor wax mirror treatment

The sand, dust and wax marks on the ground must be cleaned up. After being thoroughly dried, according to the requirements of different grades, professional equipment and high-quality wax materials are used for surface polishing construction.

Cleaning and washing:

XI。 external wall cleaning

According to different building structures and wall materials, in view of the binding force between dirt and the surface of objects, professional exterior wall cleaning agents and glass cleaning agents are selected, hanging baskets or hanging ropes are used, and equipment including high-pressure water guns and cleaning machines are used for construction operations.

Twelve. Glass cleaning

Use glass scraper, wiper and efficient glass cleaner to thoroughly remove dirt, and use glass spatula to remove dust and cement glue from window frames and window joints. The cleaning agent contains antistatic components, and the scrubbed glass is crystal clear.

Thirteen. Floor cleaning and waxing

The surfaces of marble, granite, terrazzo, artificial marble, wooden floor, PVC plastic floor and glazed floor tile are cleaned and waxed.

If the original floor has a wax layer, wax it before cleaning. According to the dirt on the surface of different materials, choose cleaning agent, cooperate with sweeper and water absorbent, and construct synchronously. The surface must be free of dust and dirt, completely absorbed and free of water.

Waxing on the ground: there must be no hidden dirt under the wax surface, and the wax surface should be evenly covered, and there must be no omissions and bubbles on the wax surface. The wax surface should be smooth and full, with soft luster and dignified texture.

Fourteen, carpet cleaning (pure wool carpet, blended carpet, chemical fiber carpet)

Use imported carpet cleaning machine and use different cleaning agents for different carpet stains, and then suck up the cleaning solution and dirt. If the stain is serious, you can clean it several times. After cleaning, the carpet suede is free of dust, the carpet surface is bright in color, combed neatly and fluffy, and the texture is elastic.

Fifteen, large chandelier cleaning

Crystal chandeliers are generally difficult to clean. In order to solve this problem, through exploration and practice, advanced spraying method and special cleaning agent for lamps are adopted, and it is not necessary to disassemble the lamps. The crystal chandelier after cleaning has no dirt, no corrosive effect on metal parts, and the lighting is bright and transparent, which is very luxurious.
