Semi gres 30×30 cleaning
If during the place, proper cleaning was not performed and cement left whitish spots on the surface of Semi Gres. In this case, the indicated would be to wait at least five days for glue salts completely rise to the surface and then proceed to clean, for that we recommend mixing 1 liter of nitric acid with 3 liters of water and then wash the surface with this preparation, this solution covers approximately 20 sq/m (wear gloves and boots). Leave acting the mixture for 30 minutes and then rinse with plenty water and mop. You can repeat this procedure at intervals of 3 days until the white patches disappear completely. Once the surface remains clean colorless wax can be applied.
The use of ocher, wax color, or diesel is not recommended, these products stain ceramics.
Placing instructions:
1.- It is advisable for settlement the use of glue, this material promotes a cleaner work, ensures a smooth surface and helps waterproofing of the ceramic piece. When using sand and portland it is recommended a minimum soak in water of 12 hours before laying the tiles, to contribute to the proper setting or adhesion between the piece and glue. In both cases, leave a minimum expansion joint 3mm, this small gap allows thet the movements of contraction and expansion the subfloor suffers don’t affect the ceramic (tearing or lifting). Do not use any glue or mixture containing lime.
2.- Seat floor with a notched trowel to avoid differences in height between floors.
3.- To prevent adhesion of the cement to the part (white patches) is recommended that each 16 m² floor placed proceed to grout and immediately remove excess material using clean cloths.
Reserve pieces for future replacement.
It is suggested in any purchase, to reserve some extra m2, which will be very useful for future replacement (alterations, plumbing problems, etc.), because the tonalities from one production to another – for various reasons – tend to vary.
