Q How to protect wall from seepage / external cracks / rainfall       
Step 1 identification of all cracks / gaps between pipes/ any screw insersion / electric opening      
Step 2 Identify all the pipelines / sources of water and if any issue, need to get it fixed by the plumber      
Step 3 Identify the condition of the surface - paint is intact / plaster falling of / no plaster      
Step 4 Surface Preparation      
a If it's a brick wall with no plaster / weak plaster or plaster is falling of then first we need to do the plaster with a product called URP which is latex based and is used for consildation and bonding of concrete      
       
       
b If plaster is ok, but paint is falling of       
 All the lose particles needs to be cleaned and removed and the surface has to be made tight and strong. The surface has to be cleaned with brush and water to make the surface dust proof      
       
c Crack filling      
 All the cracks in the wall needs to be repaireed.      
 If the width of the crack is 0-5 mm then a product crack x paste should be used. This product is acylic based and is a crack filler      
 If the width of the crack is 5-10 mm then the crack filler crack x shrinkfree to be used. This product will make sure that the cracks do not increase       
 All the above cracks needs to be opened using putty blade      
       
 For cracks with width above 10 mm, the crack should be opened using a grinding machine in a v-shape manner, and then the crack should be filled with a polymer modified mortar using the product URP or should be filled using PU sealant      
       
d If any gaps are there between the pipe and wall / any screw or inforcement is putroting outside, then the PU sealant should be used to fill the area      
       
 For any waterproofing the surface should be bought into SSD condition before starting the waterproofing. That is surface saturation dry, in other words, the surface by the touch is dry but by the look is wet. If is neccaary as cement as the property to above water.      
 Every waterproofing product has water content in them. If SSD (most important thing) is not done, then the concrete will start absorbing water from the waterproofing film and thereby will result into de-bonding      
 Waterproofing      
1 If the surface application area (top surface) is a cement / plaster then a primer called primse seal to be used to ensure the bonding between the wall and the waterproofing      
2 WPC coat to be applied       
3 Raincoat top coat to be applied as the final coat. The top coat can be applied in any colour as required.
