Description
Technical field
The present invention relates to a kind of putty pastes, and in particular to a kind of wall putty paste and include the putty layer formed by it
The wall coating system for exempting from priming paint.
Background technique
In building field, coating system for leveling wall surface generally include leveling putty, putty layer, prime coat and
Top coat layer.In order to obtain ideal smooth surface of wall, above each coat is generally indispensable.However, from construction angle
For, reducing by a coat means to save coating material and manpower, time cost.It is therefore desirable to be able to reduce one or
Multiple coats.
As one of coat for leveling wall surface, wall is normally used for substituting traditional putty with putty paste
Powder has the advantages that coating efficiency is high, dust is few, is more and more closed as the top layer putty of wall body decoration
Note.However, in view of the characteristic of putty paste itself, it is not usually especially desirable with the adhesive force of finishing coat.It is ideal in order to obtain
Mating coating system, it usually needs in the surface primer coating of putty paste, to improve its adhesiveness with finishing coat.
Still need improved wall putty paste in coatings industry.
Summary of the invention
