Understand the repair method of poor density and insufficient strength grade of plastering mortar, and solve the problems easily, so that you can truly become an old driver of plastering engineering, and your profound wisdom is very enlightening
The master always solves the problem quietly without being aware of it

Original: wall restoration engineer

Any project will have risks, and what ordinary people do cannot be perfect
To take over the plastering work, we should face some risks with an ordinary mind
You are an expert at predicting risks in advance, and you are an expert among experts who can easily resolve problems when they arise

 
To solve the problems of poor density and insufficient strength grade of plastering mortar, there is a material called sand without trace, which is very interesting
The full name of sand traceless is sand traceless wall desanding repair fluid, also known as sand traceless plastering mortar repair fluid, short for: sand traceless or sand traceless
It doesn't mean glue or interface agent in the traditional sense
Although there are similar types, most of them are not specialized materials
It is a water-based material, non combustible, solvent-free and formaldehyde free
Sand traceless is a new substance generated after chemical reaction with some active ingredients in the mortar through its special material properties
After the reaction is completed, the original loose and incompletely formed plastering mortar can be re formed to form a dense and solid structure (like stimulating the potential)
The purpose of sand removal and ash removal can be achieved by changing the mortar structure and improving the mortar strength density
Its use method is also very simple
It can be operated by spraying machine, spray for watering flowers, or even agricultural spray
If the construction area is small, it can even be operated with watering can and portable car washer
After opening the package and stirring it evenly, it can be sprayed directly
Simple, fast, convenient and practical are the essence

 
Some people ask, can I use a roller brush? It's not impossible
But strictly speaking, the roller brush does not have the pressure when spraying, which is not conducive to the penetration and absorption of materials
Moreover, the wall is not completely flat, and the spraying is not uniform

So, to what extent is it appropriate? How to calculate the dosage? Generally speaking, on the premise of keeping the wall dry and free from foreign matters, it is appropriate to fully wet the wall during spraying so as not to flow away
The specific method is to master the pressure of the spray gun and the appropriate distance from the wall when spraying, so as to make the material fog, the wall wet, and then move the gesture horizontally, so as to master the progress
In this way, generally, the amount of spraying for one time is about 2-4 square meters per kilogram, and the penetration depth is usually 3-5mm, which depends on the actual conditions such as the water absorption and dryness of the wall
The worse the density of mortar, the faster the absorption of materials, and the deeper the penetration
Of course, the amount of materials will be more
If the density and strength of mortar is too poor, it needs to be sprayed for more than 2 times, and the penetration depth of some walls can reach 1cm
In addition, if the wall is only sprayed once, the material will penetrate into the interior, and the external effect will not be obvious after drying
Such a wall also needs to be sprayed twice
The specific method can be adjusted according to your needs and site conditions

It should be noted that for spraying in several times, attention should be paid to the interval of each step
Generally, it is about 30 minutes to spray the second time
If continuous spraying, the previous wall material will not be absorbed before continuous spraying, and it will flow away after more continuous spraying, which will cause unnecessary waste
After spraying, the effect can be seen in 2-3 hours, and it can be seen in 30 minutes
The complete reaction usually takes 8-24 hours

 
One last interesting thing
In order to save materials, some friends should not imitate the recently popular long bearded artists Tiktok when painting with needle inkjet, which is not recommended by us
