Pool Sealing with NSG Co. Products
The pools have different finishing layers among which the cement membrane is discussed underneath:
As NSG products are water-based and are not able to adhere strongly to the oil-based surfaces, the surface should be free of any extraneous material by exfoliating the surface.
Clean the entire surface from petroleum-based materials; remove all loose parts of the structure that have not adhered properly to the structure; and finally, remove all pool junctions and joints if they are hollow or fissured.
If there are deep or surface cracks on the wall or the floor of the pool, open the cracks in a V shape and clean them.
Repair the cracks to uniform the surface by NSG-N50, a product with %25 Waterproofing and a %75 strengthening properties. This product should be used as a repair mortar, which consists of water, NSG-N50, cement, and silica. Use sand instead of silica in the cases that the coating should be done in thicker layers.
Apply cement fillet for the needed spots with NSG products.
At this stage, the structure is fully (%100) sealed. Now apply NSG-Z9, the product with %100 sealing property, based on the procedure 222 (This procedure consists of two steps, each is done 2 times).
Mix NSG-Z90 with water in a 1:1 ratio (one unit of water + one unit of NSG-Z90). This mixture can be used on the wall and the floor by a paintbrush and/or pistol such that the entire surface is smeared with this material. This should be done twice (Do it once and redo it after drying).
Apply the NSG-Z90 grout which is the combination of NSG-Z90, water, cement, silica or powder based on the following instruction: Apply this grout on the wall and the floor with a paintbrush to the extent that the whole surface is coated. Then, redo it again after drying.
Note: In the spots that are under tensile and bending stresses (such as concrete fillets and corners etc.) it is necessary to use NSG-PLC mesh after applying NSG-Z90 grout and fill all the mesh fountains with the grout.
In this step, which is the final step use NSG-Z90 according to the instructions described in step 5-1.
Note: In the cases that the final surface needs to be painted, water-based paints can be used. For this purpose, apply a mixture of 3 units of paint (instead of water) and 1 unit of NSG-Z90 in step 5-3.
