5.    Instructions for Use

(1). Before processing, make sure tile adhesive has completely dried out and tiles are firmly fixed.

(2). Mix Kam Chung joint mixture powder and water in 25 : 6.5 proportion (approximately 6.5 liters of water for 25kg of powder).  Stir it well and make it in paste state. Motor stirrer is preferable.

        (processing with a pointing trowel)

(3). Normally gaps are between 2 and 15mm wide. Clean them up and make sure no debris or water left inside. As for materials with water permeability, such as terracotta brick, operators can first wet the gaps between them for better bonding.

(4). Use of professional pointing method or specific rubber pointing trowel is recommended so as to make the mixture firmly pressed in gaps. Decrease on hardness could be avoided by that way.

(5). Tile surface could be cleaned by moist cloth or sponge 20 minutes after pointing. And final cleaning could be done when joint mixture completely dries out.

(6). If there is any hole or bubble spotted, fix it with pointing trowel.

(7). Powder mixed with water should be used up within 3 hours. If project takes place at high temperature condition and moisture dries out too fast, supplement of water and remixing could make it usable again. But if mixture is starting to harden, it cannot be used anymore.

(8). For some materials, such as unglazed tile and granite block, it is not easy to clean up the joint mixture on the surface. Weak oxalic acid or tile detergent could help to do this.

(9). When it is raining or below 3 degrees centigrade, do not proceed the installation.
