建筑物的外墙装饰,既要求美观大方,又要求经济耐用。最近,我们试验成功了一种简易而经济的外墙装饰法。这种装饰的具体做法是:首先用50号混合砂浆打底,再抹1:2水泥砂浆面层,然后刷两遍稀释的硫酸亚铁,俗称黑矾即成,干后呈橘红色。稀释硫酸亚铁的配合比为一两硫酸亚铁加半斤清水,搅拌均匀后使用。如果要做成假瓷砖或假面砖,可在面层抹完稍干一会,勾出所需要的图案,然后再刷黑矾。
The exterior decoration of a building requires not only beautiful appearance but also economical durability. Recently, we successfully tested a simple and economical exterior wall decoration method. The specific method of this kind of decoration is: first use the No. 50 mixed mortar to make a base, then wipe the surface layer of 1:2 cement mortar, and then brush twice to dilute the ferrous sulfate, commonly known as black wolfberry, and become orange-red after drying. Diluted ferrous sulfate mix ratio of one or two ferrous sulfate plus half a catty clear water, stir and use. If you want to make a fake tile or a false-faced brick, wipe it out on the surface for a while, draw out the desired pattern, and then brush it again.
