TECHNICAL QUESTIONS

Are the products different for each place of use?

When choosing a tile, it is also important to consider the characteristics of the place where it will be installed, for example: whether the environment is indoors or outdoors; if you have heavy traffic; whether the surface is flat, uphill or downhill; and if there is a need for frequent cleaning. These factors will prevent potential future issues such as cleaning difficulty and safety.

Can bleach be used in coatings?

Bleach is a very popular cleaning product, especially in the maintenance of bathrooms and kitchens. However, if bleach is used pure, it will chemically attack the ceramic tile, staining it. To clean the environment with bleach it is necessary to dilute it in the ratio 3 by 1, i.e. 3 liters of water per 1 liter of product. Bleach should be used diluted at this rate, because if used pure, it causes damage to the coating.

Can we use porcelain tiles on walls?

Yes. In addition to specific wallcoverings, porcelain tiles can also be use there.

How to cut porcelain tile?

For straight cuts with a width of 10 cm or more in pieces smaller than 60x60 cm, you can use the ceramic cutter, but the widia should be in good condition. To make the cut, a single and firm scratch is made on the piece (with the help of a scribe) and then the normal cut. Using the Makita disc (at 86-337) it is recommended for narrow cut-outs and / or cuts on pieces larger than 60x60 cm. The cuts should be made within 5 cm of the edge of the tile. For holes, use diamond drill. It is very important to use the right disc and drill to get the perfect finish. To pierce the porcelain tile, a different technique and the use of special materials are required. Therefore, we advise you to look for a specialized technical team to perform the services (installing, cutting and drilling) in porcelain.

How to do a post construction cleaning?

For the removal of grout based on cement and mortar, it is recommended to use white vinegar within 30 minutes after grout application. It dissolves excess of these products on an average time of 15 minutes. Then simply clean it with a sponge (preferably a special blue crystal sponge to avoid scratching) with a little powdered soap, rinse with plenty of water and dry with a clean cloth. For waterproofing or wax removal, the indication is neutral detergent or wax removers suitable for this purpose. Never use acid-containing products to try to clean ceramic tiles as they chemically attack the product.

Note: In any type of product, you should not use laundry detergent as it creates a layer and facilitates the adhesion of dirt.

How to do daily cleaning?

Ceramic tiles are synonymous with practicality and ease of maintenance. For daily cleaning, it is first recommended to dry clean by vacuuming or sweeping, then cleaning with water and mild detergent. In cases of dirt that is difficult to remove, cream soaps may be used. Ceramic tiles may present different types of stains, and you can remove them using the appropriate product for each stain.

How to extend the lifespan of the tiles?

1 - Protect furniture feet with carpet or felt, avoiding damage to the tile in case of contact with sand.

2 - Use door mats with direct connection to the street, ensuring that excess abrasive dirt impregnated in the shoes is removed.

3 - In environments that have polished porcelain with large flow of people, besides the organic doormat, make a kind of ceramic mat with satin tiles near the access areas, allowing a transition to the shiny material, thus increasing their durability.

4 - Avoid dropping heavy or sharp objects that may cause splinters on the glazed surface of the tiles.

5 - Keep the tiles always clean, free from abrasive dirt.

6 - Bleach is one of the most commonly used products for cleaning tiles, especially in wet areas of the home, such as kitchens, bathrooms and service areas, but when used undiluted, it can damage the pieces. It is recommended to dilute in proportion of one part bleach to three parts water, thus ensuring efficient and safe maintenance.

7 - The use of white alcohol vinegar associated with cream saponaceous (CIF) enables efficient cleaning, removing stains from various sources: grouts, greases, aluminum.

 

How to install products with high tonality or infinity design?

Some collections have purposeful shade variation in order to reproduce the same richness of detail found in natural materials that inspire the most diverse collections, and provide harmonious and characterful environments. This shade variation has a classification, as follows: products with uniform appearance - V1, low variation - V2, moderate variation - V3 and high variation - V4. The installation of highly visual variant tiles, classified as V3 and V4, requires attention. The best result will be achieved by a good product distribution, mixing pieces from different boxes, depending on the shade variation. The tip is to open four or more boxes and take one piece from each and set the pieces sequentially. The same should be done with new boxes until the installation is completed. For overlapping arrangements, the same orientation should be followed. It is important to remember that the arrangement must be a maximum of 30% of the length of the piece.

While shade variation is about color, visual variation deals with different designs in the same collection. Some types of tile have an intentionally caused visual variation that adds great value to the product. The so-called infinity design is a striking, continuous and standardized effect achieved through cutting-edge technology. The result is the composition of pieces different from each other, with unique designs, within the characteristics of each line, providing a bold look. It tends to decorate different spaces, which gain personality and style with the unique details in each piece. To install, follow the same procedure as above.

How to remove protective wax from polished porcelain tiles?

The wax aims to protect the polished porcelain surface. During the installation of the product, aggression to tile parts may occur due to sand, grout, external dirt, etc. The wax is applied after the surface polishing process, leaving a thin layer that leaves the surface matte. It should be removed only after the product is installed and grouted and after all job has been completed. Removing the wax will restore the porcelain shine. It can be made directly with glass cleaner or neutral detergent, rubbing the product with a blue sponge, suitable for crystals. Some polished porcelain tiles have a plastic protective film in place of the wax. In such cases, simply remove the plastic and then clean with neutral detergent or an alcohol-soaked cloth.

Is there glazed and unglazed porcelain tile?

Yes. There are two types: glazed porcelain tile, which is one that receives a layer of glaze on the surface, and the technical porcelain tile or full body, in which is the one in which the surface finish of the product is made directly on its body.

What does BOLD and RET mean?

BOL and RET are different types of finishing that give the final dimensions of a tile. A BOLD product is one that has not gone through the cut process, so its sides are bulged. These products should always be installed with joints farther apart than the rectified ones.

 

RET finish products, after the plate burn, undergo a cutting process on their sides made by diamond grinding wheels, which guarantee fine and precise dimensions, allowing a complete alignment during the installation.

What is a porcelain tile?

Porcelain tile is a ceramic product declared by ISO 13006 - NBR 13818 with BLa specification, which means it is a pressed material with water absorption less than or equal to 0.5%. Porcelain tile is obtained from high purity raw materials, subjected to compaction pressures above those used in conventional ceramic materials, and also to a heat treatment. The result is more homogeneous, very dense, glazed and more resistant than conventional ceramics. In addition to being less porous, it is less susceptible to stains and has a very low water absorption index. Because of this, its durability is truly excellent. This makes it suitable for high traffic locations such as airports, stations or shopping malls. The fundamental difference between ceramic tile and porcelain tile lies in the technology behind its manufactures. Porcelain tile has a more technologically complex process and a more controlled outcome than ordinary ceramic. It is made with a mixture of porcelain and various minerals, and goes through a burning of over 1,200 degrees Celsius.

 

What is chemical attack?

Although coatings have high strength, the chemical attack is the wear, or corrosion, caused by improper use of cleaning materials. This process makes the coating porous and can cause brightness loss and matte spots, punctual as well as sequential. The chemical attack is irreversible. The solution is the removal and replacement of damaged pieces.

What is class of use?

A product's class of use is related to its abrasion resistance, that is, the wear and tear of shoe soles or tires in contact with abrasive dirt on the glazed surface of the ceramic tile. It is one of the most important features when buying. It is important to choose the product according to where it will be used, as a proper usage class can provide more beauty and longer coating life. On the contrary, an improper choice can doom a high quality product to a very short useful life.

Class of Use 1 – Usage in walls.

Class of Use 2 - Usage in bathrooms and residential bedrooms.

Class of Use 3 - Usage in residential premises with no communication to outside areas.

Class of Use 4 - Usage in all residential facilities.

Class of Use 5 - Usage in all residential facilities and medium traffic business environments.

Class of Use 6 - Usage in all residential facilities and high traffic business environments.

What is the care of satin products?

Cleaning satin products is simple. It should be made with mild detergent and water, rubbing lightly with a cloth or sponge. An important caution: the use of epoxy grouts with this tile is not recommended. The process of applying or removing excess product may leave the shiny parts on the sides, forming a frame.

 

What is the mortar used for laying porcelain tiles?

Use mortar type AC-3 and AC-3E, according to the Brazilian standard NBR 14081, which specifies the adhesive mortars. For porcelain tiles, do not use cement-based mortars. Why: Porcelain tile has almost zero water absorption, which is lower than other coatings. Conventional cement mortars are not suitable for gluing porcelain tiles, nor are they suitable for gluing glass or plastic.

 

What is water absorption?

The water absorption of a tile is related to its mechanical resistance. The lower the absorption, the less space there is between the particles for water to penetrate the tile. This feature ensures:

- High mechanical resistance, supporting heavy loads, even with lower weight and thickness than natural stones.

- High resistance to frost, allowing to be used in places with very cold climates.

- Very low expansion by hydration, not unsticking if well installed.

Ceramic tiles are classified in relation to the group of absorption according to NBR 13817/1997.

What products are indicated for barbecues?

To coat the barbecue outside, we can use any ceramic tile from Portinari. In contact with fire, yellow high alumina refractory bricks are indicated, separated from the barbecue structure by an insulating rockwool plate. Barbecue adhesive mortars must be elastic, type AC-2 or AC-3. The barbecue must be insulated with an elastic joint / desolidarizing joint (flexible polyurethane over cellular billet, for example). In this way, the barbecue area heats up and cools everything that is necessary, without affecting the surroundings and without touching it rigidly.

Where should I use non-slip products?

Non-slip products are suitable for outdoor areas, exposed to rain and moisture, or places that need greater safety when walking. However, the rougher surface of the non-slip products, which prevents slipping, also influences on cleaning. To wash this type of tile, it is ideal to use powdered soaps and a hard bristle brush. It is a bit heavier cleaning, so non-slip porcelain tiles are not suitable for places where cleaning needs to be frequent.

What is Dry Joint?

Visual Unique - Portinari Products can now be installed with Dry Joint

  • What is Dry Joint?


Most ceramic tiles need to be installed with spacing between the pieces. The Dry Joint, then, is when these spacings do not exist. That is, the dry joint is basically touching the pieces of tiles together. This makes the look very homogeneous, as the dividing lines are very discreet, causing the sensation of a single panel. Portinari now also has this advantage for the Tiles produced from July 1, 2020. For the perfect alignment of the pieces with dry joints, it is important to follow the laying arrow on the back of the piece. The arrows must always be positioned to the same direction.

  • What is special about our products to make and guarantee a Dry Joint?


Portinari products are monocaliber. This technology is combined with strict quality control throughout the manufacturing process, the very low expansion by humidity (<0.1mm / m) and thermal expansion, combined with perfect grinding that guarantees properly squared products and minimum size variation between parts (maximum 0.3 mm). With this control, our products maintain the same format, regardless of the manufacturing batch.

  • What are the advantages of using Dry Joint?


The advantages of using Dry Joint are numerous. Unique look for the spaces where the products are applied, where the junction of the piece is imperceptible. In wall applications, it feels like a single panel. In addition, the use of dry joints ensures easy cleaning, as it does not accumulate dirt between the parts. The dry joint is also the guarantee of using less grout in the work.
 

  • Which products can be installed with dry joints?


All products rectified above 30x30 can be applied dry joint. Except parts with well-defined lines or that can be rotated. In these cases, we recommend the use a joint of 1 mm. You can check the product's joint specifications on the website.

It is important to check if the place you want to apply is indicated to use dry joints.

Exceptions of Dry Joint locations
Ceiling of any environment;
Floor in the shower box;
Floor to floor;
Heated floor;
Floor and wall of sauna, pool and cold room;
Barbecue, fireplace and plasterboard walls;
Wall above 3 meters.

If the previous floor has been applied with a Dry Joint, can I apply the new one with a Dry Joint (floor on floor) as well?
No. Floor on floor cannot be used with dry joints.


Can the dry joint be used outdoors?
The dry joint can be used outdoors, in the following cases with the use of grout:
On walls and walls up to 3 meters and on covered balcony floors, sidewalks, around the house, pool deck.
For walls above 3 meters, ceiling and inside the pool, we recommend the 2mm joint.


Can dry joints be used in bathrooms?
Dry joints can be used on the walls and floors of the bathroom and we suggest using grout. In the case of the box floor, as it is a wet area, the orientation is to use the 2mm joint.

Dry Joint means no grout, or should we put grout too?
The grout is suitable for all spaces, even if the pieces are glued together, it is interesting to use the grout to seal and give a better finish between the pieces. Choosing a grout of the color of the product, the application will give even more visual unity to the pagination.

Is it necessary to apply a special grout?
Common cement grout mixed with water should not be applied, as it will loosen over time. It is necessary that the grout has "glue" to guarantee adherence. Grouts such as acrylic and epoxy are the most recommended. But the cementitious grout can also be mixed with an additive instead of water, in the proportion of 2.5 kg of grout for 1 liter of additive.

How to identify in stock if the products are dry joints?
The identification of the Dry Joint can be made on the product packaging. The verification can be by the date of manufacture - tiles produced after July 1, 2020, and by the number of the hue (the second number will be = 1). In RC1 the tones will be from 1100 upwards. In RC2 greater than 2100. RC3, above 3100. RC4, above 4100.

How is the settlement? Do you need any specific technique?
Since it is a dry joint, the leveler is not used. The settlement follows the recommendation of the NBRs 13753, 13754 and 13755 settlement rules. The settlement base must be clean and level, the movement, desolidarization and structural joints must be respected, use suitable mortar and grout, in addition to respecting the time curing of materials. It is recommended to make double mortar bonding for formats larger than 30x30 and keep the sides of the pieces clean when laying to be able to touch each other. It is worth mentioning that for the dry joint, it is important to follow the settlement arrow on the back of the piece. The direction must always be downwards.

Does a Dry Joint cause problem with moisture, seepage?
There will be no problems with humidity and infiltration if all the installation recommendations are followed: respect the exceptions of environments that are not indicated for dry joints; follow all laying recommendations according to NBRs 13753, 13754 and 13755; practice the movement, desolidarization and structural joints; use suitable mortar and grout, in addition to fulfilling the curing time of the materials. Damp places are mandatory to grout, dry places are optional.

How many mm is the movement joint? Is the same grout used between pieces?

The same grout used between pieces is not used. The movement joint must be filled with flexible material, such as silicone or PU.

Do the drawings / details of the parts fit with a dry joint?
A great advantage of dry joint application is the perfect fit between the pieces. Product designs are no different. The pieces are produced so that the reliefs and drawings fit together, making the product even more beautiful. It is worth remembering the importance of following the seating arrow on the back of the piece.

How do I remove a replacement part in dry joint installation?
To remove a seated piece with a dry joint, it is necessary to break the product from the center to the sides. And never from the sides to the center, so as not to damage those around.

Will C quality products also allow dry joints?

No. Only quality A products allow dry joint installation.


Can large formats be installed with dry joints?
Large formats of own production can be installed with dry joints. An exclusive differential for products produced in-house. Outsourcing products must be fitted with a 2mm joint and using a leveler.
