For the old master, exterior wall paint construction things or ease, but for the novice is not so, did not operate do not know the specific process and technology, so in the construction process there are what kinds of technology? The following powder coating powder manufacturer for you to introduce effective solutions.
Exterior wall paint construction is simply paint brush on the wall is not easy to take off, not off.
If you think the moisture resistance key refers to the oil soluble wall architectural coating, wall surface coating is not to say that can not, only many characteristics of the wall are better than the interior and exterior wall project cost is relatively higher.
Exterior wall paint construction process: 1, grinding: polishing must be carried out in the rural base or putty powder dry and impatient, can not be wet grinding to prevent adhesion sand paper harming the actual operation.
The size of the grinding sandpaper should be based on the strength of the ground surface. The coarse grinding sandpaper will cause sand marks, which will harm the actual effect of the final decoration design of the coating.
When grinding and polishing, coarse sandpaper or electric grinding machine is first used to polish and polish, and then fine sand cloth is used to polish and polish, and pay attention to the leveling of the surface layer.
After grinding and polishing, the surface dust is removed immediately to facilitate the construction of the next process.
2, stick glass fiber cloth: the selection of net yarn relative density symmetry, can not use too dense glass fiber cloth to carry out shop paste.
3, repair: before the application of the substrate for the lack of edge off the Angle, holes and other shortcomings of 1:3 mixed mortar (or polymer mixed mortar) repair.
4, cleaning: dust, powder can be used broom, brush, high pressure water cleaning, vegetable grease ── the application of neutral cleaning agent cleaning; mortar -- remove with shovel, scraper, etc.; aspergillus flavus -- outdoor high pressure water cleaning, with cold water immersion wash air.
5, make up for putty powder, part of the batch of putty: if the wall is flat and smooth, do not use putty powder; in addition to easy batch grinding and polishing, the provisions of putty powder should also have good compressive strength and persistence. When carrying out the construction of filling and partial batch of putty, it should be a thin batch rather than suitable for thick brush.
It is stipulated that putty powder should have stronger adhesion, adhesion persistence and wear resistance.
6, batch putty to grind: the use of polymer putty powder scraping leveling, the key goal is to better grind paste glass fiber cloth caused by the uneven situation, avoid the surface of the hole gap.
7, architectural paint brush coating: architectural paint brush coating stipulated rural grassroots surface water content can not exceed 8%, such as in the case of wind, rain, fog until the temperature can not carry out the overall surface layer of architectural coating; construction requirements according to the design plan to make sample wall, until the project acceptance deadline.
Wall of architectural coatings engineering projects of rural grassroots putty powder and surface building coating, surface architectural coatings and architectural coatings differentia depends on the proportion of granulates, generally low proportion of exterior wall coating, it can resist rain and resistance to fall off, so the exterior wall coating are generally not required in the internal wall (except but also is to have, is when the engineering and construction of water absorption capacity is higher, Engineering buildings (south of the majority) are also painted outside inside.
