Plastering walls is an integral part of any house build or renovation – it leaves a smooth, robust finish you can admire for years to come. Here are the best plastering options for your project
Plastering walls is a skilled job that requires a meticulous application. By applying plaster, you will give your walls a strong, smooth, durable finish. Not only that, but a well-plastered room will help to keep old walls in good condition, provide the perfect base for paint and help with soundproofing.
The type of wall and surface you are plastering will determine the plaster you need and the application route you take. Plastering a new wall or over plasterboard will be different from plastering straight onto old brickwork or an existing wall.
Initially, we remove existing coats of paint, plaster and other disturbing materials from the masonry. This measure also removes most of the damaging salts. We then prepare the masonry for the application of the rough cast.

Our 2nd step: Improving adhesion
Perfect adhesion of the renovation plaster on the masonry is imperative for a permanent renovation success. For this reason, we apply a roughcast for better adhesion before Renovation Plaster. This is done in a net-like manner in order to ensure an excellent adhesion of the renovation plaster.

Our 3rd step: Plastering
At last, we apply Renovation Plaster to the wall. Depending on the degree of salinity, the plaster is applied in one or two coats. Due to its diffusion capacity, Renovation Plaster ensures the drying of the residual moisture of the masonry.
Cement Mortar Cement Mortar is one of the most common and cheapest binding materials used in construction industry. Cement mortar is basically a mixture of cement, sand & water. It is used in various aspects of civil engineering works such as masonry, brickwork, plastering, flooring etc. There are two types, dry mortar and wet mortar.
The preparation of the cement mortar involves following steps:

Mixing of ingredients
(a) Selection of Raw Materials
Although there are different types of materials available for the preparation of Cement Mortar, it is necessary to ensure that the right materials are selected based on the type of construction and its purpose.
Sand provides strength, resistance against shrinkage and cracking. It provides bulk to mortars, hence, making it economical. Using just cement would not only make it extremely costly, but also impractical.
(b) Proportion of Cement Mortar
The Proportion means the relative quantity of different components to be mixed to make good mortar, or simply the ratio between different materials.

鋪磚施工方式
硬底鋪磚施工 – 最為標準施工方式, 耐久堅固
軟底鋪磚施工 – 不會打底,先將水泥砂漿加水混合後覆蓋地面,再將瓷磚逐塊貼上,非常考施工
大理石施工法 – 基於板材較厚和重,而產生的瓷磚施工手法
玻璃磚施工法 – 先打補強鋼筋和十字固定,玻璃磚牆必須設支線點掛線強化結構
文化石施工法 – 可建成木板牆或RC牆,RC牆就要打毛用益膠泥,木板牆就是用鐵網再上水泥膠化
(c) Mixing of Ingredients
To prepare cement mortar, cement and sand are properly mixed in dry condition. Water is then added gradually and mixed using a shovel. The water should be free from clay and other impurities. Cement mortar can either be mixed manually (Hand Mixing) or mechanically (Machine Mixing). For small construction, hand mixing is commonly used. Mechanical mixing is required when the mortar is needed in large quantities and needs to be used in continuous order.
Cement gains strength with hydration. So, it is necessary to see that the mortar remains wet until hydration occurs. After placing the mortar/concrete, the process of ensuring sufficient moisture for hydration is called curing. Curing is ensured by spraying water. Generally, curing begins 6–24 hours after using mortar. Initially, more water is required for hydration, which can be reduced gradually. Curing for cement mortar is recommended for 7 days.

Precaution While Using of Cement Mortar
After adding water to the mixture, the mortar should be used within 30 minutes, because the setting process begins immediately after adding water. Otherwise, its strength will gradually decrease.
Before placing the structural units, i.e. bricks and stones they must be saturated in water because the cement requires a good amount of water for hydration. If dry units are placed on the mortar, they will absorb water from mortar very quickly, which will have a deteriorating effect on the mixture and its strength will get reduced.
Wherever the mortar is used, it should be kept wet at least for 7 days.
