Paints And Colours | An Architect Explains

Paint is used to protect (metal to retard corrosion, and a building to help protect it from the  elements), preserve, decorate (add festive trim to a room’s interior by adding color) or add functionality to an object or  surface by covering it with a pigmented coating (by modifying light reflection or heat radiation off a surface and the use of color to identify hazards or to identify the function of an equipment). Physically, paint is a mixture of four important elements: Pigments, Additives, Binders and Solvents.

One of the most often asked query by my clients is about Paints. The incredible choice and colours that are available in today’s market will confuse anyone. As an Architect, practising in Bangalore, I use my practical experience gained over 20 years to advise my clients. I trust brands that have been in the market for years because I see that the maintenance costs are much less compared to cheaper, unknown brands. Even in the choice of colours, I prefer to guide my clients to the following pages, wherein I have discussed the colour wheel, colour groups and themes, their effects on our well-being:

    Hi Hemendra Shah,
    Renovo is a water-repellant, synthetic plaster used for plastering, both old as well as new, external and internal walls.

    Hi Sir,

    I am Arun writing from Chennai. I read Your article “Paints – Architect Explains”. I found it to be very helpful in understanding the basics of paints. However I have question and would like to have Your inputs on that. My apologies for the inconvenience.
    I have got a resinous wood (Indian Kino, Pterocarpus marsupium, vengai in Tamil) for my windows and doors. This wood bleeds and hence I was advised to apply some kind of finish to stop it before plastering. I requested for technical assistance from Asian Paints and got the following response. The PU Painting procedure for the wood which contains resin , oil etc. is as follows:
    Step 1) Sand the Wood With sand paper No. 80, followed By 100, 120, 150, 180 .
    Step 2) Apply 1 coat of Polyester Insulator by wipe. Wait for 30 min & Put 2nd coat of Polyester insulator.
    Step 3) Wait for 1 hour sand with sand paper no. 320 & apply 2 coats of PU sealer by spray as recommended.
    Step 4) Sand the surface with sand paper 320 followed by 400.
    Step 5) Apply 2 coats of Top coat by spray as recommended.
    Can You please explain the difference between polyester paint (Asian Paint Woodtech Polyester) and PolyUrethane paint in terms of wood finish chemistry. Doesn’t Polyester Insulator suffer from the same problem as PU or does it play the role of shellac mentioned in the article mentioned above. Also does the Polyester insulator and PU sealer/top coats go well with each other.
    My apologies for any inconvenience caused. Thanks
    Hi Arun Deepak,
    Honestly I have no idea about paint chemistry and it’s properties. So I cannot help you.
