In the construction of wall painting, the selection of coatings is the primary task and an important factor affecting the entire construction process. However, in the process of selecting paints, consumers often have the following misunderstandings. Today, Xiaobian is the four misunderstandings for your fine coatings, so that you can be a smart consumer.
Misunderstanding 1: Anti-cracking paint must be crack resistant
Regardless of the old house in the new house, the phenomenon of cracking the wall is very much. Many people have tried their best to choose a good paint to solve the cracking problem. I have seen a famous brand of paint packaging that says "anti-cracking". Many consumers think that as long as they use these paints, they can prevent wall cracking and other problems. In fact, this does not have much effect.
Xiaobian Zhizhao: A thin layer of paint film can prevent the cracking of the wall surface, which is unlikely. The "elastic latex paint" currently on the market generally only compensates for microcracks below 0.3 mm. If the wall has been cracked and you want to solve these problems, it is best to use latex paint to make up, or use cement to fill the cracks and paint.
The auger bit adds a long deep spiral flute for effective chip removal.
Two styles of auger bit are commonly used in hand braces: the Jennings or Jennings-pattern bit has a self-feeding screw tip, two spurs and two radial cutting edges. This bit has a double flute starting from the cutting edges, and extending several inches up the shank of the bit, for waste removal.
The Irwin or solid-center auger bit is similar, the only difference being that one of the cutting edges has only a "vestigal flute" supporting it, which extends only about 1â„2 in (13 mm) up the shank before ending.
The diameter of auger bits for hand braces is commonly expressed by a single number, indicating the size in 16ths of an inch. For example, #4 is 4/16 or 1/4 in (6 mm), #6 is 6/16 or 3/8 in (9 mm), #9 is 9/16 in (14 mm), and #16 is 16/16 or 1 in (25 mm). Sets commonly consist of #4-16 or #4-10 bits.
