Indigo Stain Block Primer is a water based primer suitable for use on interior / exterior walls and ceilings. It is specially formulated to prevent the migration of stains through the finished paint film. It can easily hide the stains caused by water and solvent based inks, crayons, ball-point pens, coffee, grease, spices and cooking oils, water, nicotine and smoke damage.
Surface Preparation & Application:
To get the best results, ensure surfaces to be painted are sound, clean and dry (new surfaces particularly must be fully dry) and free from all defective or poorly adhering material such as efflorescence, dirt, grease or wax. Where necessary, surfaces should be rubbed down using a suitable abrasive paper and then dusted off. To use, stir thoroughly and apply 1 coat of Stain Block Primer to the stained surfaces without diluting with water and allow to dry for 8 hrs. Two coats are recommended for difficult stains.
