Want to have a perfect cement wall? Detailed explanation of cement wall construction technology
Nowadays, there are many decoration styles. Nowadays, industrial-style homes are popular. The seemingly unfinished cement powder presents a natural and rigid unique style, which is loved by many people. However, the seemingly simple cement powder is easily affected by factors such as raw material quality, space conditions and manual experience, and presents different colors and textures. If you want a perfect cement wall, you must start with the cement wall construction technology. Today's Home Decoration Network Small The editor will explain the cement construction technology in detail.
During the construction process of cement walls, if you are not careful, sand (dust) and cracks may easily occur. Even if the construction is good, due to the material of the cement itself, cracks and discoloration will still occur after long-term use. This is normal. It is recommended to apply a protective agent on the finished surface. Commonly used ones include water-repellent agent, hardener, water-based acrylic resin, Epoxy, etc. Water-based acrylic resin and Epoxy will change the color of the cement powder. The thickness must be uniform, otherwise it is easy to have Differences in shades of color occur.
Usually, the base surface of cement powder is applied to brick walls or lightweight concrete partitions, which is not suitable for application to wooden walls. The order of application is roughly as follows:
1. Floor cleaning → 2. Rough base → 3. Surface powder → 4. Surface protection
After the brick wall is laid, The surface will be uneven, so you need to use a "rough base" first, mix cement mortar to cover the brick surface, and smooth it to ensure that the wall surface is smooth. This step is the foundation of the foundation. If the base is uneven and cannot be modified afterwards, the wall will appear like a wave.
The next step is pinking. To make the pinking beautiful, the most important thing is to sift the sand in advance. You can use a mesh sieve to filter out larger sand particles. The finer the cement sand, the smoother the surface will be. After adding water to mix, apply a thin layer of cement mortar (about 5mm) with a special spatula. Since this is a direct contact surface, it is recommended to increase the cement mortar ratio to 1:2 to enhance its strength and Abrasion resistance. You can take 1 to 2 courses.
Wait for the cement to dry to 70 to 80 degrees (about 7 days), then use a trowel to smooth the surface. Because the cement has reached a certain strength and is still plastic, it can effectively reduce trowel marks during leveling. Adjust the timing of the technique based on the master's experience, hand strength, and presentation style.
After the cement mortar is completely dry and hardened, use a sander to grind the surface until it is fine and smooth; small areas can also be treated manually with sandpaper. This Taoist contract renewal is repeated 2 to 3 times. This results in a smooth cement pink finish.
Finally, apply a water-repellent agent (water-repellent agent) on the surface as a protection to properly block moisture, reduce staining and other problems, and increase the strength of the finished surface. If you want to strengthen the surface protection, you can use water-based acrylic resin or Epoxy instead. The former will slightly deepen the color of the floor and give it a slightly dated feel; the latter has strong protective power, but the coating is thick, shiny and unnatural. Because both will form a film on the surface and are easily slippery when exposed to water, they are not recommended for use in wet areas such as bathrooms or toilets.
