The dirt on the exterior surface seriously affects the beauty of the building, and the cleaning cost is a large amount of expense. Therefore, before the construction of the exterior surface, we can start from the selection of the exterior material and the construction detail planning, so as to avoid future troubles.Selection of external Wall materials1） Ceramic claddingCeramic tiles have been used for wall cladding design since Ancient Egyptian times. In more recent times, terracotta rainscreen cladding and brick slip systems are popular choices for construction projects.Because ceramic tile is the most common dirty, start from ceramic tile seam, base material, adhesive and filling seam agent are the important key that affects quality, if quality is not good, can produce the phenomenon that fills seam agent to flow dirt, ceramic tile falls off or reverse alkali.
2)Stone claddingInnovative stone cladding systems that simply slot together have been developed to make stone cladding practical and cost effective. Stone cladding brings a level of detail and heritage with it that is truly unique.But stone material has wool stoma, bibcock rate is higher, main pollution phenomenon has water spot, spit yellow, blotch, fill joint material pollution to wait, these pollution is easy to go into stone material interior, more difficult to clear.It is recommended to adopt the dry construction method to avoid the anti-alkali phenomenon after the wet construction method's stone and cement mortar contact, while the jointed iron in the dry construction should be made of stainless steel or treated with rust prevention.
3)Metal cladding&Curtain wallMetal cladding can be a great supplement to your wall cladding design providing that modern, industrial look and feel. It is also very useful for incorporating bold colours into the project.As outside facing material, aluminum and glass curtain wall without thermoplastic problem, has the characteristics of the porous material, smooth surface, less accumulation of dust, but due to the electrostatic adsorption phenomena of smaller particles suspended particles, below the runoff pollution components, so we need to rely on detail design technique processing, paint and caulking agent of choice is especially important, because the caulking agent dirt caused by aging, need to repair or replace regularly.
4)Natural-stone paint&Brick Texture Exterior Wall PaintNatural stone paint often due to thermoplastic effect produced back adhesion, easy to adsorb sticky dust cleaning is not easy, so the stain resistance is not good, after the completion is easy to appear small shortcomings, so usually by the surface layer or bottom layer do more waterproof to protect.
Construction detail planning1）Good facade designThe design of eaves, water guiding system, etc. can effectively guide the water flow to prevent rainwater from directly affecting the facade. When planning, the design first will help reduce the concentration of dirty pollution.
2）Make a water tangent to the outer wallMake a drip line on the outer wall to allow rainwater to drip from about 1-1.2m in each section of the outer wall, and use a cut-off line to prevent water from approaching the wall to avoid water seepage in the building. This method is simple and effective.
3)Rain deflectorThe rain deflector combines the design concept of water tangent line, and uses its own engineering principles of "water diversion, water blocking, and water diversion", so that the design of rainwater alluvial dust diversion will not extend along the wall and directly drip to the ground. Most of the problems of dirty black water remaining under the exterior walls and window sills, which saves time and effort.Use a rain deflector, the adapter is usually connected with a corner device, and the adapter must be tightly sealed with silicone. The professional water deflector adapter has a reserved card hole on the back of the card, as long as one coats two sets of three The small secret of light pressure can be easily installed, allowing the adhesive to penetrate and the tiles to be fixed and combined. There is no need to punch or squeeze to insert the reserved holes, which will increase the risk of the construction personnel operating at high altitudes or the accessories Beware of the safety risks of falling from a height.
