Requirements for Full Tile Paving in Mobile Toilets
When fully paving tiles in mobile toilets, attention should be paid to pre-treatment, formal paving, edge finishing, and other details. The specific key points are as follows:
Pre-treatment Stage: Ensure that the ground foundation meets the standards. First, thoroughly clean the ground to remove dust, debris, and oil stains, ensuring that the ground is flat without any bumps or depressions to avoid hollow spaces during subsequent paving. Second, handle the floor drain. When fully paving, reserve a floor drain opening and lay a waterproof blanket (such as polyethylene waterproof membrane) around it. Seal the edges of the floor drain with waterproof coating (such as polyurethane-based) to prevent moisture from penetrating into the lower structure. If there are cracks or holes in the ground, repair them in advance with cement mortar and allow them to dry.
Formal Paving Process: Strictly follow the process specifications. First, evenly apply a layer of cement mortar about 3-5mm thick on the ground (with a cement-to-sand ratio of 1:3) and use a scraper to smooth it out to adjust the slope. Pave from the toilet entrance inward, first performing a dry layout (without applying adhesive) to determine the alignment of tile joints and color matching, and then apply adhesive and press each tile into place one by one. Key control points include: maintaining a tile joint width of 2-3mm (which can be controlled with cross-shaped spacers), using a level to check flatness (with an error ≤ 2mm), following the paving sequence of 'from inside to outside, from top to bottom' to ensure that the corner tiles are consistent with the overall direction; if the space is narrow, pave the corners first and then extend towards the middle.
Edge Finishing: Consider both functionality and aesthetics. After paving is complete, use cement strips (such as PVC or metal) to divide the tile surface, keeping the lines straight and aligned with the tile joints to enhance overall flatness. Install anti-slip strips (made of materials such as rubber or silicone) in areas prone to slipping, such as around the toilet and in the corners of the shower area. The recommended width is 5-8cm, and the height should protrude 2-3mm above the tile surface to ensure anti-slip effectiveness.
Other Precautions: These should be observed throughout the construction process. If pursuing spatial continuity, strictly control the details: the ground slope should tilt towards the floor drain (with a standard slope ≥ 1%) to avoid water accumulation; prioritize the use of anti-slip tiles (with a friction coefficient ≥ 0.6) and pair them with long floor drains (with a length ≥ 60cm) to improve drainage efficiency; regularly inspect the grout (recommended every 6 months) after construction, and promptly refill any cracks or detachments to prevent moisture from penetrating into the base layer, which could cause mold or tile hollow spaces.
