NEOSEAL FLEX 550 acrylic cementitious coating shall be applied as per the following general method of application:
A. Substrate preparation:
The performance and ultimately the durability of the coating largely depends on the condition of the substrate.
Therefore, conditioning and preparation of the substrate is of utmost importance.
Concrete surface:
The surfaces shall be thoroughly cleaned to remove all dust particles and laitance.
Surface defects like cracks, holes or voids in the concrete needs to be repaired using an appropriate polymer modified mortar (PMM) within the correct ratio of (1:5:15).
After the surface needs to be in SSD condition not with standing water.
B. Mixing
The material is supplied in two parts and pre measured. Take the liquid in a container and slowly add the powder to the liquid and mix using a slow speed drill fitted with a suitable paddle mixer until a lump free consistency is obtained.
Do not mix more material than that can be used within 50-60 minutes. Mix thoroughly and keep mixing the material during application. Do not add water at any stage.
C. Application
Apply with a short stiff bristle brush or roller once the 1st coat is applied to achieve the desired thickness. Apply the 2nd coat after the 1st coat is completely dried to achieve a minimum thickness of 1.8 – 2 mm.
