Provided is a masonry treatment composition containing a fluorine-containing polymer, which contains, as essential components, a fluorine-containing monomer having a fluoroalkyl group represented by the formula (a) CH 2 =C(-X)-C(=O)-Y-Z-Rf, a first hydrophilic monomer represented by formula (b) CH 2 =CX 11 C(=O)-O-RO-X 12 , a second hydrophilic monomer represented by formula (c) CH 2 =CX 21 C(=O)-O-(RO) n -X 22 or CH 2 =CX 31 C(=O)-O-(RO) n -C(=O)CX 32 =CH 2 , and (d) repeating units derived from a monomer having an anion donor and an ethylenic unsaturated double bond. Provided is a treatment composition which can impart outstanding water repellency, oil repellency and antifouling properties to a masonry substrate. |
