Berger Chlorinated Rubber Base Paint — Protective Paint for Metal and Masonry in Karachi
Berger Chlorinated Rubber Base Paint is a protective coating from Berger Paints. Available at Saify Paint House, an official Berger Paints stockist in DHA Karachi, it is used on surfaces that need protection from water, humidity, and corrosive conditions.
Berger describes it as compounded from plasticised, chlorinated rubber and specially selected pigments. According to Berger, it is far more impermeable to water and water vapours than any oil or varnish-based paint, which makes metal surfaces corrosion resistant.
Why Choose a Protective Coating
Some surfaces face conditions that ordinary paint does not handle well. Berger’s page lists steam, constant high humidity and condensation, acid or salt-laden atmospheres, and alkaline vapours among them. Coastal Karachi has salt-laden air and high humidity, so Berger’s list of conditions is relevant to many outdoor metal and masonry jobs in the city.
Berger’s page also describes it as a one-pack product suitable for application throughout the year.

Surface Preparation & Application
Berger says pre-treatment of the surface is necessary before painting. Berger’s page does not spell out the steps, so ask our team which pre-treatment suits your surface, whether it is steel, concrete, or brick.
As general guidance, the surface should be clean, dry, and free from dust, grease, loose rust, and flaking paint. Remove loose material by scraping, wire brushing, or sanding first.
Berger advises applying the first coat with a fully loaded brush, and not to cross brush the work repeatedly. Berger recommends spray for later coats. For spray, thin the paint with Berger’s special Chlorinated Rubber Base Paint thinner, as Berger advises. Berger states the paint dries in about one hour and can be recoated after 16 hours.
Common Mistakes With Chlorinated Rubber Paint
The most common mistake is skipping the pre-treatment. Berger says it is necessary, and a coating laid over a dirty or rusted surface will not protect the metal beneath it.
Cross brushing the work again and again is another. Berger specifically asks for care here, because repeated brushing disturbs the film. Using the wrong thinner is also a risk. Berger calls for its own thinner for spray, so do not substitute another solvent.
Recoating before 16 hours can disturb the coat below. Plan the next coat around Berger’s recoat time, and keep the work out of rain or condensation while it sets.
Care, Storage & Safety
This is a solvent-based paint, and its thinner is flammable. Keep the tin and thinner away from heat and naked flames, and work in a well-ventilated space. Wear suitable protection for skin and eyes, and avoid breathing spray mist.
Close the container properly after use and keep it upright. Protect it from extreme hot or cold temperatures, and keep it out of reach of children. If the paint gets into the eyes, rinse with clean water and seek medical advice.
Choosing Between Berger Protective Products
Saify Paint House stocks several Berger products for metal and masonry. Chlorinated Rubber Base Paint is the protective base for harsh conditions. For a primer on metal before a gloss topcoat, ask about Berger Red Oxide Primer. For a metallic finish on metal, ask about Berger Aluminum Paint. For a gloss topcoat over primed metal, ask about Berger VIP Super Gloss Enamel or Berger NU Enamel. For plaster and masonry, ask about Berger Waterbased Primer or Berger Plastron Wall Primer. Visit our Berger Paints range to compare them.
Where damp or seepage is present, treat the cause before painting. See our Ressichem building care and waterproofing range.
Planning Your Project
Measure the area and use Berger’s coverage figure of 8 to 10 m² per litre per coat to estimate how much paint you need. Remember that the paint is sold in 3.64 litre packs, and that more than one coat is usually needed on protected surfaces. Our team can work out the quantity with you, along with the pre-treatment and thinner.
