Adhesive residue — practical guidance and quality checks

"Glue stains" requires determining the cause before selecting a fix. The visible symptom itself does not tell you which layer or stage has failed. The most important thing is to stop the cause, document the condition and control the result before covering or collecting.

Cracked tile — practical guidance and quality checks

A cracked tile may be the result of impact, lack of support, ground movement or stress. Replacement without checking the substrate may result in another crack. The most important thing is to stop the cause, document the condition and control the result before covering or collecting.

Debonding tiles — practical guidance and quality checks

“Detaching tiles” may indicate incomplete support, a weak substrate or loss of adhesive adhesion. The scope must be checked beyond one visible place. The most important thing is to stop the cause, document the condition and control the result before covering or collecting.

Hollow-sounding tiles — practical guidance and quality checks

“Dead tiles” may indicate incomplete support, a weak substrate or loss of adhesive adhesion. The scope must be checked beyond one visible place. The most important thing is to stop the cause, document the condition and control the result before covering or collecting.

Insufficient shower fall — practical guidance and quality checks

"No slope in the shower" affects water drainage and the tightness of the wet zone. Correcting the grout or silicone itself usually does not change the geometry of the substrate. The most important thing is to stop the cause, document the condition and control the result before covering or collecting.

Lippage or protruding edges of tiles — practical guidance and quality checks

Protruding edges of the tiles are caused by uneven surfaces, curvature of the tiles or incorrect level control. The assessment should take into account the format, light and the required standard. The most important thing is to stop the cause, document the condition and control the result before covering or collecting.

Misaligned tiles — practical guidance and quality checks

“Tiles stacked crookedly” requires determining the cause before selecting a fix. The visible symptom itself does not tell you which layer or stage has failed. The most important thing is to stop the cause, document the condition and control the result before covering or collecting.

Missing waterproofing beneath tiles — practical guidance and quality checks

The lack of waterproofing under the tiles in the water-exposed zone is a defect of the layering system. Tile and grout do not replace a tight under-tile layer. The most important thing is to stop the cause, document the condition and control the result before covering or collecting.

Poorly cut tiles — practical guidance and quality checks

"Badly cut tiles" requires determining the cause before selecting a correction. The visible symptom itself does not tell you which layer or stage has failed. The most important thing is to stop the cause, document the condition and control the result before covering or collecting.

Tile discolouration — practical guidance and quality checks

"Discoloration on tiles" requires determining the cause before selecting a correction. The visible symptom itself does not tell you which layer or stage has failed. The most important thing is to stop the cause, document the condition and control the result before covering or collecting.

Tiles at linear shower drain — practical guidance and quality checks

"Tiles at the linear drain" affects the drainage of water and the tightness of the wet zone. Correcting the grout or silicone itself usually does not change the geometry of the substrate. The most important thing is to stop the cause, document the condition and control the result before covering or collecting.

Tiling defects for remedial work — practical guidance and quality checks

Not every glazing error requires chipping the whole thing off. The extent of the correction depends on stability, tightness, geometry and the ability to achieve a consistent effect. The most important thing is to stop the cause, document the condition and control the result before covering or collecting.

Uneven tile joints — practical guidance and quality checks

"Unequal tile spacing" requires determining the cause before selecting a fix. The visible symptom itself does not tell you which layer or stage has failed. The most important thing is to stop the cause, document the condition and control the result before covering or collecting.

When need to remove tiles — practical guidance and quality checks

Shipping the tiles is necessary when the defect concerns the substrate, waterproofing, slope, extensive detachment or it is impossible to perform permanent repairs from above. The most important thing is to base your decision on measurements, extent and the consequences of covering the defect.

Wrong adhesive for porcelain tiles — practical guidance and quality checks

The stoneware adhesive must be selected according to the format, substrate, conditions and loads. The mere indication "for tiles" does not confirm compatibility with a specific application. The most important thing is to stop the cause, document the condition and control the result before covering or collecting.
