Short answer:<\/strong> Add-On is Turbolux’s multi-purpose cement primer. It is a water-based undercoat that seals porous cement plaster, evens out absorption and gives emulsion a firm grip on interior walls, exterior walls and cement roof surfaces. If you want one affordable primer for the whole house, this is it. For damp-prone walls, step up to a waterproof primer like Super Seal, and for premium exterior repaints use the dedicated Exterior Primer.<\/p><\/div>\n

What is a cement primer and what does it actually do?<\/h2>\n

Fresh cement plaster is porous, slightly alkaline and thirsty. Roll emulsion straight onto it and the wall drinks the binder out of the paint, leaving a patchy, weakly bonded film that chalks and peels early. A cement primer solves this in three ways.<\/p>\n

First, it seals the pores so every coat of paint that follows stays on the surface where it belongs. Second, it evens out absorption, so the finish coat dries to one uniform sheen instead of blotches. Third, it forms a bridging layer that the emulsion can key into, which is why primed walls routinely outlast unprimed ones by years. We covered the wider case in Do You Really Need a Primer Before Painting?<\/a>, and the answer on bare cement is always yes.<\/p>\n

Where can you use Add-On in a Kerala home?<\/h2>\n

Add-On is deliberately multi-purpose. One 10-litre pack can prime most of a mid-sized job, which keeps things simple for contractors and budget repaints. Typical uses:<\/p>\n
