Greetings, esteemed experts.

As a professional in the building industry, I have noticed instances of paint flaws in houses shortly after the completion of projects. The primary causes of this issue are the presence of seams, the movement of water by capillary action in the bricks, and the infiltration of water into the walls. Another possible factor could be the limited duration of construction, which allows less time for the plaster on both interior and exterior walls to dry.

I would want to inquire about the availability of any chemical or polymer that may be added to the mixture of Portland cement and sand during the plastering of walls, both indoors and outdoors. The purpose of this addition would be to permanently seal any pores in the plaster, ensuring that no water can escape through them.

I require a cost-effective solution.

Thank you in advance for your assistance.
