Rectified

Near-perfect straight edges and exact dimensions. These tiles provide a very clean, symmetrical look, and allow for extremely fine grout lines of 3mm or less. Laying rectified tiles is a slower process than laying traditional “pressed” edge tiles and may also cost more even though they are straight edge. If you are going to lay rectified tiles, we recommend you also use a levelling system to insure a level finishes free of lippage.

Pressed

Pressed edged tiles or cushion edged tiles have a “rolled” edge which means the grout joint will be larger than a rectified tiles as the tiles cannot be laid as closely together. The cost to install these is generally less than rectified tiles.

Summary

Rectified tiles may take longer and be slightly more expensive to lay, however they aesthetic appeal of the smaller grout joints in conjunction with the use of a proper levelling system to ensure a perfect job, will far outweigh any cost. It will also allow you to better line up grout joints to create a seamless floor tile or wall tile design.

Most dust pressed tiles have a tolerance of + or – 0.5% of its length and width.  Many manufacturers, however, grade their tiles by size (calibre) to much tighter tolerances than allowed.  It is not unusual for a 330 x 330mm floor tile to only vary 1mm in a batch when the standards allow a tolerance up to 3mm.

Tile Ratings

“Tile

There are two main types of shade variation: Batch Variation (variations between production runs) and Unique Variation (intentional variations manufactured into the tile).

Batch Variation

Tile shade variation is part of the porcelain and ceramic tile manufacturing process. It is not a defect. Almost every porcelain and ceramic tile has some degree of variation, even in the same production run (batch). The shades of the tiles may be similar to those from previous batches, but they’re unlikely to be the same. It’s therefore best to buy all material to be installed at the same time.

Ideally tiles from different batches shouldn’t be laid together. If for some reason they must be, then it’s wise to carefully compare tiles from each batch before installation.

Please note: In-store display tiles are an indication of the tile. Colour and design my vary between sample and actual tiles supplied.

Unique Variation

Tile printing technology is always advancing, meaning there are now greater ranges in patterns and shades incorporated into tile design. Tiles imitate natural materials like stone, timber or marble—all of which vary substantially in appearance, and often have a unique look.

Tile shade variation ratings indicate the degree to which a tile’s colour, tone and texture vary among individual tiles. Tile shade variations are categorised from V0 – V4, and are usually detailed in the product’s technical specifications. See Tile Variation Categories below for more details. When choosing your tiles, we recommend checking the shade variation rating, if available. We also recommend you dry lay V3 and V4 tiles prior to installation—to make sure you’re happy with the range of variation, and the overall look.

Tile Variation Categories:

		V0 = Very Uniform Appearance Pieces of the same shade value are very uniform and smooth in texture, with little or no variation.
		V1 = Uniform Appearance Differences among pieces from the same production run (batch) are minimal.
		V2 = Slight Variation Clearly distinguishable differences in texture and/or pattern within similar colours.
		V3 = Moderate Variation While the colours and/or texture present on a single piece of tile will be indicative of the colours and/or texture to be expected on the other tiles, the amount of colours and/or texture on each piece may vary significantly. It is recommended that the range be viewed before selection.
		V4 = Substantial Variation Random colour and/or texture differences from tile to tile, so that one tile may have totally different colours and/or texture from that on other tiles. Thus, the final installation will be unique. It is recommended that the range be viewed before selection.

 

Tiling

The creation of a beautiful well completed new or renovated bathroom, kitchen or any other area with wall or floor tile installations is a very satisfying experience. To ensure that there are no expensive errors, regrets or on-going maintenance problems, and that you actually have achieved what you intended, usually requires the skill and experience of a professional tile layer.

As tile layer registration, accreditation or endorsement is not compulsory in all states in Australia, it is sometimes a concern as to who you actually choose to install your pool tiles.

The following steps should be of assistance.

Ask for a Written Quotation

It is very important for you to know the cost involved. A written quotation from a tile shop Melbourne or Brisbane wide demonstrates that both parties understand what work needs to be done to achieve an excellent job. The more detail in the quote, the better, as it assists avoid disputes at a later date.

You should agree on the price prior to any work starting. Ask the tiler for their references, whether they are qualified and their trade experience.

Compare Prices

Obtain 2 or 3 quotations. This will give you a realistic idea of how much the installation should cost. Remember that price is not the only criteria and that you may only get what you pay for.

Check References

A reputable tradesperson will always allow you to make contact with 2 or 3 of their recent customers so that you can make enquiries about the quality of their work and their conduct on the job.

Ask Yourself These Questions

• • Was the tile layer easily contactable?
  • Did they arrive on time?
  • Do they appear content to do the job?
  • Do they appear to have time to do the job?
  • Was the quotation delivered on time, fairly priced and did it cover all work required?
  • Has the tile layer returned my calls?
  • Am I comfortable with this person to handle my work?

Look at the Complete Picture

Price is not everything. Lowest prices could mean poor workmanship, but the most expensive prices do not necessarily guarantee the best workmanship. Remember that workmanship includes presentation, minimum amount of inconvenience, cleanliness and overall professionalism.

If the quotation is fair, the references are good, the timing is suitable and you feel comfortable that the tile layer understands what you are trying to achieve, then choosing the right tile layer for your tile installation should be well achievable.

BEFORE YOU LAY YOUR TILES CHECK THEM!

We Want You To Be Absolutely Delighted With Your Tiles. However we need you to ensure that this delivery is exactly what you want. Together, we can ensure that your tiling project is the best. Ensure you discuss the design of your project and your expectations with the tiler and that you include any special arrangements in the contract, for example, the extent of clean up required.

Please check the tiles that we have delivered. If there is any concern regarding the quality, shade or defect of the tiles supplied by us, please inform us immediately.

However ceramic tiles are a natural product and some variations can be expected in shade and size. Australian standards define the acceptable variation and imperfection allowable in any batch. 

We will not accept any claims for replacement, repair or reimbursement once tiles have been laid if that claim is for defects, size, shade variation, incorrect delivery or shortage, or any thing that should reasonably have been obvious before laying commenced. 

It is the responsibility of the tiler, builder or homeowner to check tiles before laying them. If there is any concern regarding the quality, size, colour, shade or variation of the batch on site, the tiles must NOT be laid. 

If a defect is discovered while tiles are being laid…work MUST STOP IMMEDIATELY AND YOUR SUPPLIER MUST BE CONTACTED. 

Mosaic Tiles

Due to the technical limitations in the manufacturing process, mosaic tiles are subject to greater shade variations than other ceramic tiles. Ensure that you are happy with the colour and shade variation before installing the tiles. 

Prior to laying any tiles the tiler, builder or home owner must check the following:

1. Tiles Received

That the description corresponds to clients colour selection and the client has inspected and approved the product.

2. Shade & Size

That the Shade Code (Tonality No.) and Calibre Code (Size) is the same on ALL cartons.  Arrange for your tiles to be delivered well ahead of time. Check the tone or shade markings of all the tile cartons to ensure that you have been supplied with tiles from the same batch. Open two or three cartons and inspect the tiles for correct colour and acceptable shade. Failure to do so may result in disappointment as fixing of the product constitutes acceptance of the product.

3. Quantities

Ensure that there are sufficient tiles to complete your job, as there are no guarantees that extra tiles of the same batch (colour and shade) can be supplied at a later date. If possible, order more of the same batch (tone) before work commences. It is suggested that a small quantity of extra tiles be kept on site after the job is finished. It can be very difficult to match tiles if repairs are necessary at a later date.

4. Defects

That you inspect the tiles for any defects and DO NOT LAY tiles that have visual defects.

NO CLAIMS WILL BE ACCEPTED BY THE TILE SUPPLIER AFTER TILES HAVE BEEN LAYED.

Laying Your Tiles:

• • In all cases the appropriate type of adhesive must be used. The substrate must also be adequate for the material to be used, that is, the flatness of the surface is paramount. If not tile lipping may occur. 
  • In the case of floors, uneven surfaces may be levelled out with the use of a floor leveller or floor screed. Your tile fixer should be able to guide you through any questions you may have, so don’t be afraid to ask.

During Laying:

As tiling commences, make sure that the light in the room being tiled is as close as possible to the perma­nent lighting. Ensure the tiler mixes tiles from three or four different boxes so as to ensure proper blending of any colour variation that may exist.

As the work progresses, take time to have periodic checks:

• • Ensure that the blend and effect is maintained and no defective tiles are laid.
    
  • It is highly recommended that hidden areas (under the stove, fridges, in pantries and cupboards) or detached areas (toilets and laundry floors) are tiled last so that if extra tiles are needed, batching will not be crucial.
  • Always clean adhesive, grout and wax from the surface of tiles. 

It is essential that, if you have any doubts or concerns about the job as it progresses, you stop the tiling and immediately contact your tile supplier before tiling any further.

After Laying:

Cleaning is the next step of the installation process. Ensure that the tiler removes all;

PLEASE NOTE: In the production of tiles, certain technical limitations will occur, which may manifest themselves in the form of minor marks and blemishes. The latter are generally considered a characteristic of the tile and not a defect. Under normal lighting condi­tions these characteristic marks may not be noticeable. However, they may become obvious when highlighted by some forms of oblique lighting, for example, halogen and high illuminate white lights. All tiled surfaces should be viewed from a distance of 1.5m under non-critical light. Further, make sure your expectations have been met by inspecting the finished job whilst the tiler is still on site.

Wall Tiling

To calculate your area in square meters, multiply the length by the height of each wall to be tiled. When ordering the tiles add an extra 10% for waste & cuts. You will require an even, flat surface to tile on. Prepar­ing the walls is a vital part of the tiling process – failure to do so will result in an unsatisfactory finish. Waterproof wet areas according to the manufacturer’s specifications prior to tiling.

Floor Tiling

To calculate your area in square meters, multiply the length by the width of the room. When ordering tiles, add an extra 10% for waste & cuts (15% if laying diagonally)

New concrete is recommended to be l month old for every 25mm thickness and completely dried before tiling. It should also be a wood float finish, flat and free from dirt, dust and oils. Wooden floors must be rigid, stable and capable of the extra load without flexing. Generally an underlay will be required to tile on wooden floors.

Floor Adhesives

Generally, it is recommended to use normal or fast setting adhesives. However, always consult your tile merchant for detailed advice and always follow the manufacturer’s instructions. Mix the adhesive as per manufacturer’s instructions and spread with a notch trowel. Place each tile into the adhesive firmly with a backward and forward movement to ensure a solid bed and to prevent any voids under the tile. Be careful to remove any surplus adhesive from the surface of the tile and joints with a damp sponge/cloth.

Work in small areas of about l square metre at a time so that the tiles are fixed before the adhesive forms a skin. Occasionally use a spirit level or straight edge to check that the tiles are flat. If needed, remove and adjust the amount of adhesive, being careful not to leave it too long or the adhesive will set.

Note: Lippage is inherent in all installations and may be unavoidable due to tile tolerances.

To prevent the chance of disturbing the bonding process, do not walk on or grout floor tiles for at least 24 hour, unless a rapid set adhesive has been used. Force the grout into the joints using a grouter, removing all surplus grout from the surface with a sponge and water.

Daily Cleaning Guidelines:

• • Sweep or vacuum loose dirt off the floor.
  • Use a proprietary cleaner, following the manufacturers instructions
  • Remove the cleaning solution with a clean mop or vacuum.
  • Rinse with clean water.
  • Remove water from the floor by drying and buffing with a dry towel or mop.

General Maintenance

• • Glazed Ceramic and Porcelain Tiles – Maintaining these surfaces can be achieved by sweeping or vacuuming and then washing the area using a specialised tile cleaning agent available from your tile merchant. Rinse surface thoroughly afterwards, using clean water. Residual streaks, detergent marks and films can be a result from excessive use of cleaning agents.
  • Unglazed Tiles – All unglazed products do have a level of surface porosity which usually means more attention is required to retain cleanliness. Spills or accidents that result in contaminates on the surface may stain. Often, unglazed tiles are sealed for ease of maintenance or future cleaning.
  • Glass and Metallic – When cleaning these tiles be careful not to use abrasive applicators such as scouring sponges.
  • In some instances, on advice from your tile merchant only, acidic cleaners may be needed for optimal results. These products must be recommended by your merchant as suitable for your particular tile application.
  • Do not use acid, unless recommended by your merchant, to clean fully glazed tiles as this may affect or damage the surface.

Generally, the longer a stain has been left on a tile, the more difficult it will be to remove. Where possible, consult your merchant about the type of stain you are trying to remove, as there are specialist products for cleaning.

Grout

Many grouts on the market have mould inhibitors which can help reduce mould growth. Mould can still occur if the condi­tions are severe or if a grout without mould inhibitor has been used. Mould can be removed using specialised grout cleaners.

Efflorescence

Efflorescence is a white discolouration caused by minerals in the cement that are soluble in water, being dissolved and transported to the surface as the water evaporates. It is most noticeable on dark materials but can occur on any cement based system. 

This is not normally a problem as only insignificant amounts of white discolouration make it to the surface of the grout during normal curing. However, because it is water soluble, under certain conditions the migration of the discolouration to the surface can be increased. Therefore if the system takes longer to cure or if there is more water present during curing, there is more time available for it to be carried to the surface. 

Sometimes minor efflorescence can be removed by using normal cleaning methods, whilst more difficult stains can be treated with specific products for your merchant. Ensure the grout has had sufficient time to cure or you may make it worse by increasing the water on the surface.
