PURPOSE:To obtain a water paint capable of removing malodor developed in the dwelling space, by adding a deodorizing substance capable of removing malodor and highly porous aggregate and filler to a water paint and adjusting the pH of the mixture to a specified value. CONSTITUTION:A deodorizing substance capable of removing malodor by a chemical combination, neutralization or inclusion is added to a water paint. Highly porous vermiculite, perlite, expanded polystyrene, diatomaceous earth, etc. are used as aggregates and fillers, and the pH of the paint is then adjusted to 6.0-8.0. Examples of the compds. having a deodorizing effect are vegetable compds. such as flavanol, org. compds. such as abietic acid, inorg. compds. such as reduced iron and porous inorg. compds. such as activated carbon. Examples of the highly porous aggregates and fillers are vermiculite, perlite and silica gel. By mixing them with the paint, the coated surface is made uneven and the coating film is made gas-permeable, whereby the contact area of the deodorizer with malodor can be increased.
