製備混凝土表麵的指南
November 20, 2020While we often discuss using finishing processes on metal, they also play a critical role in concrete surface preparation. A concrete surface in need of repair or coating should go through the preparation process to ensure successful results. Below, you’ll discover the fundamentals of concrete surface prep and your options for completing the process.
我應該什麼時候準備我的混凝土表麵？
在修理或完成混凝土表麵之前，您應該通過擺脫不合作的混凝土並粗糙化。製備過程實現了這兩個目標。不合作的混凝土可以出現：
- Visible cracks or microcracks in the concrete
- 由混凝土表麵下的被困氣泡形成的水泡
- 通過冷凍水膨脹混凝土而產生的縮放
- 剝落（剝離或剝落混凝土）
- 分層（分離表麵的糊狀層）
You can check if the concrete has unsound material by tapping it with a hammer and looking for any resulting indents or damage. In sound concrete, the hammer will bounce.
Why Should I Prep My Concrete Surface?
The concrete preparation process determines the success of surface repairs and coating bonds. To make concrete repairs that last, you’ll need the repair material to bond to the surface securely. An inadequately prepared concrete surface can cause the concrete and the repair material or coating to debond.
在不合作的混凝土的情況下，非疑問層會隨著時間的推移分離自身，導致進一步的損壞。當您在正確準備的表麵進行維修時，修理或精加工和混凝土將作為一個單元粘合。
How Do I Prep My Concrete Surface Using Surface Roughening?
想知道如何混凝土？這隻是準備混凝土表麵的幾種方法之一。正確的行動方針取決於具體的粗糙度。準備混凝土涉及修理或整理的步驟包括：
- Using mechanical methods, like sandblasting, to remove unsound concrete from the surface
- Cleaning any surface contaminants present on the concrete
- Roughening the concrete surface to prepare it for a coating or overlayment
在準備期間需要蝕刻我的混凝土嗎？
During concrete surface preparation, you can use a variety of methods to roughen the surface, including etching and abrasive blasting. Learn more about some of the most common techniques used in this preparation step below:
- Acid etching:Performs light abrasion for sealants, films and coatings.
- 欧宝体育下载苹果磨料爆破：為粗糙表麵剖麵造成光滑的表麵型材，以進行整理和修複疊加。
- 水噴射：Can dislodge coarse aggregates for thick coatings and repair overlays.
Should I Use a Special Polish on My Concrete?
When choosing a coating for your prepped concrete surface, consider getting a coating created specifically for concrete. These finishes feature sealing properties for concrete and often hold up better on the concrete’s rough surface. Some general coatings and resins also work well for concrete, so we recommend consulting your supplier to see what they suggest.
