What's paper-reinforced ash? How to do?

The paper-reinforced plasters that we are giving you as an example today are a product accessory processed from grass or fibers, which are often mixed evenly in specific proportions into the plastering mortar and used for plastering the walls. On the one hand, they are cheap basic materials, so the cost performance is excellent, on the other hand, after a special treatment, so can be used in the field of construction engineering, play a beautiful and protective role, and in order to achieve the later satisfactory results, but also should be combined with the paper reinforcement gray construction technology and process skills advice to start to carry out detailed and careful study, including specific ratios, the selection of tools and so on are more critical. It is more critical to learn about the specific proportions, choice of tools and so on.

First, what is the paper reinforced ash

Paper reinforced ash is a kind of grass or fiber material processed into a paste, according to the proportion of uniformly mixed into the plaster mortar, the role of the wall to prevent cracks in the plaster layer, to increase the strength of the mortar connection and consistency. The weight capacity including priming gray is generally 33KN/~35KN/. If the quality is okay, it is not recommended to shovel, if necessary, you can scrape putty leveling in the surface layer, and then brush paint.

The paper reinforcement ash is a mixture of paper reinforcement and lime viscous stuff, paper reinforcement ash wall should be compacted and calendared in a timely manner, and depending on the degree of dryness and wetness of the mortar with an iron trowel dipped in water to wipe the pressure, skimming, so that the surface layer is more delicate and smooth. Window openings and corners, wall corners and other parts of the yin and yang corners should be used respectively to push the smooth smooth light. The paper and gray cover layer should be firmly bonded, there should be no key marks, bubbles, paper particles and joints such as inequality, and the wall or beam edges of the intersection of the corners should be a straight line.

Second, how to do the paper reinforcement gray

1, grass-roots treatment: remove the wall of dust, dirt, alkali film, mortar blocks and other attachments, to sprinkle water to moisten. For the construction of too smooth concrete wall with steel mold plate, can be used to wall chiseling or spray, sweeping method of 1:1 cement mortar dispersion uniformly sprayed onto the wall, to be hardened before the bottom layer of plastering operations, in order to enhance the adhesion of the bottom layer of grey and the wall.

2, set square, hanging straight, do gray cake. Before plastering the bottom layer of gray must first find a good rule, that is, the four corners of the square, horizontal line leveling, vertical line hanging straight, popping out the baseline and wainscoting, skirting board line. For intermediate and advanced plastering, the wall surface can be checked for flatness and verticality with a line board, and the thickness of plastering can be roughly determined under the control of the squareness of the corners (the thinnest part is generally not less than 7mm), and the line can be hung to make the plaster cake (the thickness of the cake should not include the surface layer). For advanced plastering, the room should first be square, generally can first pop up on the ground as a baseline cross line, and combined with the wall leveling, vertical degree of roughly determine the thickness of wall plastering, and hanging line "to do the ash cake", "to do the ash cake", "to do the ash cake", "to do the ash cake", "to do the ash cake", "to do the ash cake", "to do the ash cake". "Do ash cake" should be done first in the left and right corners of the wall to do a standard cake, and then hanging vertical line with a wire hammer to do the lower corner of the wall two standard cake (high and low positions generally in the skirting line on the mouth), and then in the corner of the wall around the two standard cake between the surface of the through line, every 1.2 ~ 1.5m or so and in the windows and doors of the sunny corners of the top and bottom of each make up a number of ash cake.

3, the wall punch: to be ash cake hard, use the same mortar with the plaster layer, between the upper and lower cake to do about 30~50mm wide mortar band, and the upper and lower cake shall be pushed flat with a pressure ruler. After the reinforcement is completed, it should wait until it dries a little before the wall bottom plastering operation.

4, do corner protection: according to the mortar pier and door frame edge from the wall gap, with a square ruler gauge square, respectively, on both sides of the sun corner hanging straight and fixed good ruler plate, cement mortar corner protection, and with the corner of the trowel launched small rounded corners, and finally the use of the ruler plate, in the location of the sun corner 50mm away from the two sides of the angle of 40 degrees will be excess mortar cut, clean.

5, wipe the bottom layer of gray and the middle layer of gray: wipe the bottom layer of gray in the case of wet walls, the surface of the concrete wall should be brushed with cement paste once, brush with the bottom layer of gray. The bottom layer of gray should be 1:1:6 cement mixed mortar (or according to the design requirements), the thickness should be 5~7mm, to be slightly dry bottom layer of gray, and then the same mortar wiping the middle layer of gray, the thickness should be 7~9mm. if the middle layer of gray is too thick, then it should be coated by times. Then take the reinforcement as the standard, use the pressure ruler to scrape and find the straightness, and use the wooden grinding board to grind smooth. After the middle layer of gray smoothing, should be a comprehensive check of its verticality, flatness, yin and Yang angle is square, straight, found that the problem should be timely repair (or rework) processing, for the skirting after the upper mouth and behind the pipeline location should be cleaned up in a timely manner.

The above examples of paper tendon gray is not a direct use of accessories, in fact, it uses raw materials are grass or fiber material, after processing to become a slurry liquid, in accordance with a specific proportion of uniformly mixed into the plastering mortar within a class of products, their role is to prevent the liquefaction of the wall plaster layer to increase the strength and consistency of the connection of the mortar, and therefore have the effect of maintenance and aesthetics! The late construction of paper reinforced plaster should be combined with step-by-step process suggestions and tips to start detailed control, so that you can achieve satisfactory results.
