Abstract

A process and device for treating and repairing a hard surface consisting of a polymer film, such as a floor surface, are provided. The process comprises the steps of:

(i) cleaning said surface with an aqueous cleaning product comprising 0.1-20% by weight of a surfactant and 0.1-80% by weight of a solvent;

(ii) applying to the cleaned floor surface a liquid repair product, the properties of which, after drying thereof, being similar to those of the polymer film; and (iii) allowing the thus-treated floor to dry for at least 5 minutes. The device is a manually operated floor treating device specially adapted for use in said process.

Claims

1. A process for treating and preparing a hard surface having a polymer film, said process comprising the steps of:

i) cleaning a hard surface having a polymer film with an aqueous cleaning product comprising;

a) 1-5% by weight of an aminoxide,

b) a solvent mixture including 1-20% by weight of gamma

butyrolactone and 1-20% by weight of methylic diester of glutaric, succinic and adipic acids, and

c) 1-10% by weight of a builder selected from the group consisting of citrates, phosphates and mixtures thereof, percentages based on the total composition of said aqueous cleaning product, to obtain a cleaned floor surface having said polymer film thereon;

ii) applying to the polymer film of the cleaned floor surface a liquid repair product which dries to provide a repaired surface exhibiting properties as those exhibited by the polymer film including hardness, wear resistance, stick resistance, water resistance, gloss, removability and transparency; and

iii) allowing the repaired surface to dry for at least five minutes.

2. The process according to claim 1, wherein the aminoxide is cocodimethylaminoxide.

3. The process according to claim 1, wherein the liquid repair product comprises 1-40% by weight of a polymer dispersion, 0.5-40% by weight of a wax dispersion, 0.5-30% by weight of a solvent and up to 100% by weight of water.

4. The process according to claim 3, wherein the liquid repair product additionally comprises 0.1-10% by weight of a plasticizer, up to 20% by weight of an alkaline soluble resin, and up to 5% by weight of an anionic surfactant.
