Cement wall decoration, the most important thing is the late collocation, mainly gray-tone fair-faced concrete. If you make your own cement wall on the mortar surface, you can choose to use fair-faced concrete putty (available in the market, gray putty can also be used, but it is best not to crack). On the mortar surface, putty can be directly scraped. This technique is very simple, as long as it can scrape the putty evenly.
After scraping, wait until the putty layer is almost dry, and then polish the scratches on the putty, preferably with thinner sandpaper. After polishing and dust removal, you can roll-coat the alkali-resistant primer of Lanbao fair-faced concrete protective agent, which can effectively protect the putty layer from alkali return in the later stage. Roll coating evenly, and do the color of fair-faced concrete again after it is completely dried. If the color of the putty layer is similar, this step can be ignored.
After drying, the decorative effect of cement wall can be achieved by directly covering the surface, but the overall collocation needs to be reasonably configured in the later stage, and finally the corresponding overall decorative feeling can be achieved.
