To the decoration of the season, the decoration can not be sloppy, but most owners do not know inside the doorway, "foreman" cheating workers cheated material is a daunting task, "senior home improvement project supervision summed up the home improvement, you N can not but know the details. " 
 (1) refused to "electric tiger" 

 Situation of a half-way connection: pipe threading, wire connectors, circuit load is large joints prone to spark and fire. 

 Solution: Use a wire from scratch, pull the tail, in the middle do not have joints. 

 Scenario 2 floors, wires, irregular graphics between two points: the line exactly how to go who do not know, if you need repairs, you want the floor to pry open the can find. 

 Solution: the construction of the ground, pay attention to the smooth vertical and horizontal seal groove before to draw the circuit diagram and hydro-built drawings, and marked size. 

 Scenario 3 wires no insulation tube, bend unworthy link accessories: wire aging may cause a short circuit or leakage, such as the maintenance of only hit the wall corner should link accessories. 

 Solution: wire must be added to the insulating sleeve, at the same time allowed between the junction box (bottom box) connector. 

 Case 4 lighting circuits (strong) - and telephone lines, network lines (weak) on the same tube (box): with a pipe threading too much prone to fire, call or Internet generated electromagnetic interference on the circuit. 

 Solution: the strength of power should be separated, not in the same tube (box). 

 2 ahead of anti-flooding " 

 5 Chaigai waterway without experimental or seal: pressure test may cause pipes to burst or leaking. 

 The solution: do pressure test experiments, if the pressure gauge readings there is no obvious decline is not leaking. 

 Is 6 will be hot and cold water mixed pick: hot water pipes can replace the cold water pipe, but the cold water pipe to replace the hot water pipes may burst because of the expansion rate. 

 Solution: White on behalf of the cold water pipe, and red indicates hot water pipes, strict distinction. 

 (3) carefully cut corners 

 Circumstances with putty powder instead of cement: not strong, seismic capacity. 

 Solution: small area of ??putty powder can replace the cement, but a large area of ??crack and the cement used to block the groove must be consistent with the hardness of the original structure of cement. 

 8 counterfeit formula made from recycled aluminum aluminum, a glue with the world: Whether it is the hardness or the life of recycling aluminum are worse than the formula of aluminum, the price difference of 20-30%, the glass doors and windows may be used for some time because the glue is not the sun, After aging, causing the glass high-altitude fall, another example, the kitchen caused by water seepage, and the flexibility of the floor affected. 

 Solution: the doors and windows security is closely related to, you should use the formula aluminum, corrosion-resistant, long life, balcony, kitchen, flooring glue has a special glue. 

 Not. 9 waterproof paint brush but the splash, the first pass did not dry on the brush a second time; Sri Lanka did not brush before filling putty powder and water: pouring methods can not guarantee that each place are coated, waterproof paint did not dry not formed waterproof layer, then spread the second time not have waterproof, not brush Adams thinner, damp rainy weather wall, even moldy. 

 Solution: waterproof coating must use the brush, and construction must not be in wet weather or rainy days, and be sure to pass dry painted the second time. 

 10 the first pass of the brush primer, the second time against the finish, or a surface with a primer paint brush full house: A typical cut corners, whether gloss or durability are greatly reduced, curved or raised easily off. 

 Solution: The standard approach is "bottom" of the two "side", once the primer twice finish, different place with different finish.
