DE2442505A1 - Unglazed ceramic tiles pointing and cleaning - initially treating with wax, plastic or combined emulsion - Google Patents

Abstract

The process is designed to simplify the work of pointing up and cleaning the surface of non-glazed ceramic tiles, where pointing is carried out after the mortar bed, in which the tiles are laid, has set hard, and where the lack of glazing results in the retention of pores in the tile surface, with a danger of permanent scarring by mortar remaining in them and only removable by intensive chemical or mechanical action, or by scrubbing away the surface over the years - disadvantages which usually prohibit the use of otherwise attractive tiles of this type. Here the surface is treated, before laying or before pointing, with wax, or plastic, or with a wax-and-plastic emulsion. Pointing and cleaning are almost as easily effected as with glazed tiles, and the danger of permanent grease or other idrt penetration before completion is eliminated.

Description

Methods to facilitate grouting and cleaning of the surface of unglazed ceramic tiles The invention relates to a method of lightening grouting and cleaning the surface of unglazed ceramic tiles, preferably brick tiles.

The grouting is done after the mortar bed in which the tiles have set be relocated. The grout is used directly with the joint iron pressed into the open joint, which is very time-consuming and therefore inefficient is. Another option is to pour the thick grout on the surface and pushing or slurrying into the joint using a rubber slider.

As unglazed ceramic tiles with more or less open pores are interspersed and are therefore more or less water-absorbent, there is Risk of mortar on the surface "burns" and one stubborn dirt forms. Especially with brick tiles, which are very absorbent can be such pollution without harsh chemical means and without intense mechanical or machine treatment are not properly eliminated. One Self-cleaning due to the wear and tear of the surface over the years, as well encouraged by daily wet scrubbing will affect the good by then Appearance of the tile. For this reason, there has only been the option mentioned above so far with mechanical or machine treatment and harsh chemical agents that but it was so expensive that brick tiles, despite their beauty, were extremely rare were used.

Another disadvantage of the prior art is that after such a cleaning so far the complete drying of the mortar bed at least had to wait several weeks before waxing the surface could.

During the period of drying out there was, in addition to normal pollution there is a great risk of irreparable grease contamination on the ceramic surface urged. After drying out, the surface had to be cleaned again and could can only be waxed in afterwards. Were there any remaining soiling Waxed in, these were practically permanently preserved, which was because of the inconvenience of the procedure was the case very often.

Sludging the thick grout is all the more difficult, the more absorbent the surface of the tile is. The grout is namely when pouring in Removed so much water through an absorbent ceramic surface that he very quickly turns into a crumbly state in which it can no longer be processed is. If you were to keep the mortar particularly thin from the start, this would result the surface soiling, in turn, is particularly strong and permanent.

The difficult grouting and cleaning are the reason why unglazed Ceramic tiles today, despite their beauty, are almost no longer used as flooring Find.

The invention is based on the described disadvantages to eliminate.

The solution to the problem posed by the invention consists in a method of the type described in that the surface before Laying or before grouting with wax, with plastic or with a wax-plastic emulsion is treated. The surface of unglazed absorbent ceramic tiles, especially brick tiles, so it is fresh and not yet soiled Before laying or before grouting, treated so that grout mortar and dirt only weakly adhere to the tile surfaces and the residues through a simple Cleaning can be easily eliminated.

The treatment according to the invention leads to the on the surface lying pores are filled and closed. This increases the absorbency of the Material and the adhesion of the mortar is very much reduced, so that the grouting and cleaning becomes almost as easy as with glazed tiles. Besides, there is danger permanent soiling before and after grouting, e.g. by walking on, parking of dirty or greasy objects, e.g. cleaning buckets, putty buckets, etc., removed, because the surface of the absorbent and dirt-prone ceramic material is effectively protected against pollution by the treatment.

In a further embodiment of the invention, diunglazed, ceramic Tile, especially brick tile, glued to the substrate in a thin bed. Through this only a minimal amount of moisture is brought under the tile during installation, which is recorded by this itself. It therefore does not have to be before or after grouting Moisture on the tile surface dry out. Therefore can the treatment of the surface with wax, plastic or a wax-plastic emulsion can be made at any time prior to grouting, without any Wait for drying time.
