Srikakulam district sits close enough to the coast that exterior walls take a beating most inland towns never see. Salt in the air, humidity that barely drops, and a monsoon that arrives hard.
Paint that performs perfectly well two hundred kilometres inland can fail here in three years. It is worth understanding why.
What actually goes wrong
Efflorescence. Salts move through the plaster with moisture and crystallise on the surface, pushing the paint film off from underneath. You see it as white powdery patches, usually low on the wall.
Algae and fungus. Constant humidity plus shade equals growth. Green and black staining on north-facing walls is the usual sign.
Chalking. Ultraviolet light breaks down the binder in the paint film, leaving a powdery surface that rubs off on your hand.
Cracking at joints. Buildings move, and where a wall meets a beam or a column there is stress. Rigid paint films crack there first.
What to look for in an exterior paint
Flexibility. An exterior paint that can stretch will bridge hairline cracks instead of splitting along them. Look for elastomeric or flexible ranges rather than the cheapest exterior emulsion.
Alkali and salt resistance. This is the specific answer to efflorescence, and it starts with the primer, not the topcoat.
Fungal resistance. Most decent exterior systems include a fungicide in the film. Near the coast this matters more than the colour.
UV stability. Deep shades fade fastest. If you want a strong colour on a south or west wall, pay for the better range or accept that it will need doing again sooner.
The system matters more than the tin
This is the part most people skip, and it is where most exterior paint jobs actually fail.
A paint job is a system: surface preparation, putty where needed, primer, then topcoats. Spending on a premium topcoat over an unprimed or badly prepared wall is money thrown away — the film is only as good as what it is stuck to.
On new plaster, let it cure properly before painting. On a repaint, the old flaking material has to come off, or the new paint simply lifts it away later.
A practical approach for a house here
- Make sure the wall is dry and cured, and fix the source of any damp before painting over it
- Use an alkali-resistant exterior primer, not an interior one
- Two topcoats of a good exterior emulsion, not one thick one
- Pay particular attention to parapets and the tops of walls, where water sits
- Expect to repaint exterior surfaces sooner than interior ones — that is normal near the coast, not a failure

What we stock
We are authorised dealers for Berger, covering interior and exterior emulsions, primers, putty and waterproofing compounds. If you tell us the wall area and whether it is new plaster or a repaint, we will quote the whole system — primer, putty and topcoat — rather than just the paint.
