What are Valverdi tiles made of?
All Valverdi tiles are made of vitrified porcelain. This is very similar to traditional ceramic but during the manufacturing process the powder is pressed with much more force and then fired at extremely high temperatures, turning it into a glass-like substance. Once cooled the porcelain has exceptionally low porosity and is almost as hard as diamond.
Will Valverdi Indoor-Out porcelain fade?
No, the product is completely colour-fast.
Can you lay 10mm porcelain outdoors?
Technically yes, but we do NOT recommend you do this. To be successful you would have to lay it onto a de-coupling layer onto a cured and reinforced concrete bed and incorporate expansion joints as required. Additionally, the 10mm tiles do not have the enhanced slip-resistance of the 20mm. The external environment is much tougher on a tile than in the house and the 20mm tile is designed to cope with outdoor elements such as children’s bikes, gardening equipment and differential solar expansion between the tile and the concrete bed. We recommend using the 20mm tile externally and the 10mm tile internally.
Can Valverdi Indoor-Out tiles be used on balconies and roof terraces?
Absolutely! By laying onto support pedestals they can quickly and easily transform your roof terrace or balcony.
Are the tiles value for money?
Valverdi Indoor-Out tiles represent fantastic value for money as they will outlast you and should never need replacing.
Are the tiles slip resistant?
Yes. The 10mm has good slip resistance and the 20mm has added HD slip resistance to cope with outdoor elements.
Will they stain or discolour?
No, the product is non-porous and therefore resistant to staining. Additionally, due to the tiles non-porous nature, algae will not affect the surface. We tested the resistance to staining using a range of solutions – see the below video for results.
Will a hard winter damage the outdoor tiles?
No, they are completely frost-proof.
How can I avoid lipping when installing oblong tiles?
Most tiles will have a slight bow along their length due to the firing process, which is more obvious in oblong or plank tiles. This can be accentuated by certain laying patterns, but can be avoided by increasing the joint width and choosing a stack bond or 1/3 broken bond pattern. Lay the tiles out before fixing to determine the best pattern and joint width to avoid lipping issues.
Do you need to seal Valverdi Indoor-Out porcelain?
The tiles do not require sealing, however we strongly recommend using BAL Protective Sealer prior to grouting. Warmer weather can cause grout to flash dry and leave an invisible and extremely hard to clean polymer coating on the tile. Using a protective sealer will save time during the grouting process, improve the look of the grouting and help prevent a polymer coat drying on the surface of the tiles.
Will Valverdi Indoor-Out porcelain scratch?
Valverdi Indoor-Out porcelain is incredibly hard to scratch, making it suitable for both domestic and commercial applications. Don’t take our word for it though, order a sample and try to scratch it!
How do you look after the tiles?
To keep them looking good, just sweep and occasionally clean with a damp mop and LTP External Paving Cleaner. To remove scuff marks or to spring clean winter dirt use Lithofin Intensive Cleaner. The tiles are completely unaffected by jet washing.
How accurate is the sizing of tiles?
All sizes detailed in the brochure are nominal (approximate). After manufacture Valverdi porcelain tiles are rectified to the same size, but this can vary between different production runs or batches. Indoor and outdoor tiles are made on separate production runs so sizing of indoor and outdoor tiles can vary. Please contact us if you have any questions regarding the sizing of your tiles.
Can I run joint lines from indoors to outdoors?
Absolutely, however you will need to check the calibration (size) of the indoor and outdoor tiles are similar. If the sizes are different you will need to use different grout widths or stagger the joints between indoor and outdoor. See above as to why the indoor and outdoor tiles may be a different calibration. Get in touch with one of our stockists to check their current calibrations.
What is the difference between rectified and non-rectified tiles?
When porcelain tiles are made they are fired at very high temperatures in advanced kilns. However, when they leave the kiln the tiles will all be slightly different sizes due to different shrinkage rates. At Valverdi we ensure all our tiles are rectified, a process where their edges are ground to precise dimensions so size variations between tiles within a batch will be very small. This allows you to use a much narrower joint to give a clean, precise and contemporary grout joint. If you choose tiles that are non-rectified you will have to use much wider grout joints and lose that clean contemporary look you have tried to achieve.
