FAQs
It is recommended to fill very large gaps using smaller pieces of the wood itself with the help of a carpenter. Small cracks / holes can be filled by using polyester putty or multipurpose sealants.
A Primer surfacer or Primer Sealer is a primer with high binder content, this aids to seal the pores of the substrate effectively thereby enhancing adhesion and giving a uniform finish & gloss of the topcoat.
Red oxide primer is a protective coating applied on ferrous metal surfaces to prevent them from rusting and corroding due to exposure to the elements. It helps increase the life of the metal and the durability of the final topcoat.
Yes, you can use water-based topcoat or emulsion Paint over oil-based Primer or Solvent-thinnable Cement primer.
Topcoat coating interval between Oil based Primer and Emulsion Paint should be after overnight drying ie; 12 hrs, and should not be more than 48 hrs.
Oil base Primer if allowed to dry for more than 48 hours, will lead to inferior adhesion of the Topcoat.
Wood primer is the undercoat applied on wood surfaces before it is painted. The purpose is to achieve superior adhesion of the final topcoat to the wood surface. It also offers short term protection for the wood from moisture up until
the topcoat is applied. Indigo wood primer has excellent coverage, is easy to use, and dries quickly.
Wall putty helps provide a smooth and even look to the wall and is a recommended step in the painting system. Wall putty is generally applied using a putty blade and involves applying multiple coats in thin fine layers to remove any undulations and holes on the surface.
Apply two to three coats to achieve best results. Make sure the first coat is completely dry before you apply the second coat. A coat of primer must be applied to the bare wall before you apply acrylic wall putty.
Acrylic putty is a water-based composition with a smooth consistency used as an undercoat on walls to level out undulations, small holes / cracks and prepare the wall for receiving paint. Acrylic wall putty from Indigo Paints is a water-based finishing putty for interiors. It stands apart because of its superior quality, fast-drying property and ability to provide an excellent bonding between the wall surface and the paint.
Wall Putty is a well-designed mix of white cement with fine fillers and polymer, which can be easily applied on masonry walls to fill all unevenness and undulations on the wall to give a smooth crack free surface, ready for applying Paint.
Application of only white cement will form a very thin layer and not give filling on walls. It can at times lead to cracks also.
The basic difference is that primer is a liquid product used to improve adhesion between the substrate and the topcoat or primers are used to address specific issue like chalking, alkalinity etc.

In simple terms there are two types of putty. Acrylic putty and powder-based putty. Powder-based wall putty consists of white cement mixed with polymers and minerals. As it is white cement-based, it can be used on interior and exterior walls for its powerful binding capabilities.
Acrylic wall putty is a putty with smooth paste-like consistency and based on acrylics. It is generally recommended for interiors.
If the previous coating is in good condition and requires no levelling, then putty is not required for repainting.
However, in cases where the previous coating has deteriorated leaving behind uneven surface, or in order to fill nail holes and small cracks, putty will be required.
Primers are designed to improve adhesion and bind the surface. It cannot withstand the attack of harsh elements. If you don’t apply a coat of paint over the wall primer, it will most likely deteriorate and turn into a chalk-like powder.
The role of the putty is to smoothen / level; the surface and it is essentially an undercoat. It should under all circumstances be over coated using a primer, followed by two-three coats of emulsion.
Ideally puttied surfaces must be overcoated within 5-7 days and not left exposed.
It is not recommended to add colour to putty.
