  (direct sale by the manufacturer) what materials are used for plastering wall repair? Repair methods for insufficient mortar strength  
Repair method for insufficient mortar strength of plastered wall
 
1、 Plastered wall repair - Inspection
(1) When it is found that the plastered wall is not strong enough and easy to desande, first look at the area easy to desande, then look at the severity, predict the maintenance problems, and prepare the corresponding materials

(2) You can inquire and understand the key points of wall repair in advance, then repair according to the actual situation, and prepare the corresponding tools

2、 Plastered wall repair - preparatory work
(1) For the wall surface of the base course, if there is dust or floating ash on the surface, it shall be cleaned first and kept clean as far as possible

(2) If there is putty powder, paint or other pollutants on the wall, it shall be cleaned and removed until the mortar layer can be seen
If flushing method is adopted for cleaning, sand stain free repair material shall be sprayed after it is completely dry

(3) Areas that do not need to be sprayed with repair materials shall be protected to avoid spraying materials on other irrelevant items

3、 Plastered wall surface repair - sprayed sand traceless wall surface repair material
(1) Spray in a small area and test the dosage
For example, 1-2 square meters are sprayed first
Generally, the amount of spraying is 2-4 square meters with 1kg
Spray once and twice in different areas respectively
Compare after an interval of 2-3 hours
If the requirements are met by spraying once, it is not necessary to spray twice

If it is necessary to spray twice, the interval between each spraying shall be more than 30 minutes
The material use method can be adjusted according to the desanding degree of the wall
For example, 10-20% clean water can be added to the material during the first spraying to facilitate penetration and priming (no water is added during the second spraying)

(2) After the number of spraying passes is determined, large-area spraying shall be carried out
Generally, the results can be compared within 2-3 hours, and the reaction is completed after 8 hours (the reaction time may be delayed in case of low temperature or serious temperature, which is generally within 24 hours)

4、 Plastered wall repair - local material supplement
  Even for the same wall, the degree of insufficient mark of plastering mortar may still be different
If the local material absorption is too fast or the effect is different, the material can be supplemented
If it is particularly loose, the mortar can be supplemented

5、 Precautions for plastered wall repair
(1) Construction is not easy when the weather is too cold, such as icing environment
When repairing the wall, it is not appropriate to use too many materials at one time
As the wall is a facade, affected by the degree of water absorption of the wall, too many materials will be used at one time, and the wall will flow away before absorption, resulting in waste of sand free materials
We should not use too little materials
Too little materials will not work
The correct method is: spray until it is just enough to absorb without flowing away

(2) Sand traceless wall repair liquid spraying is invalid in building materials without cement
Such as putty powder, wall paint, marble, ceramics, glass, metal surface, etc

(3) In the case that the mortar wall exposed for a long time may have been weathered and foamed or seriously powdered, and the sand rubbing wall contains too much clay or impurities, the use effect will be affected
The cement component in the foamed or severely powdered plastered wall may have become invalid, just like spraying the sand on a plate of loose sand without trace
Therefore, the specific situation is analyzed in detail; If the sand contains too much soil impurities, it will affect the solidification of cement mortar

(4) Where there is too much dust on the wall surface, the floating ash and sand are not cleaned, or the wall is covered with putty, paint, paint, glue, oil stain and other coverings, because the surface materials will block the penetration and absorption of the sand stain free repair solution, thus affecting the effect, these coatings need to be removed or completely cleaned

The insufficient mark of plastering mortar is easy to remove sand and powder, indicating that the mortar structure is loose and not formed, and the absence of sand marks is to change the morphological structure of cement mortar in the plastering wall, so that the loose cement mortar can regenerate a solid and solid form through regeneration reaction
When the plastering mortar structure is compact and firm, the purpose of desanding and ash removal is achieved

Low grade plastering mortar, no trace of quick-use sand!
It's better to ask for yourself than others
The sand on the wall has no trace!
