What is the difference between ceramic & porcelain tiles?

Ceramic Tiles have been around for over 2000 years. They typically have a white or red clay biscuit with some form of glaze on top. Porcelain Tiles are made from extremely fine powdered clay that is pressed under huge pressure and heated several hundred degrees hotter than ceramics. Porcelain tiles are much harder and denser than ceramic tiles. This allows porcelain tiles to be made in very large formats that would be impossible to achieve in a ceramic tile. Porcelain tiles will also often have a coloured biscuit that matches the surface glaze, or have a colour and pattern that extends all the way through the tile. This avoids the common problem with ceramics where the glaze gets chipped and exposes the clay biscuit underneath. Glazed porcelain tiles combine the best features of both ceramic & porcelain tiles durability of porcelain with extensive colour range & lower production cost benefits of ceramic tiles.

What is the difference between wall and floor tiles?

Wall tiles are normally thinner, lighter and softer than floor tiles (because they are not intended to take weight). Wall tile glazes are not designed to handle the abrasive forces from foot traffic. Floor tiles have a different rating of hardness which makes them suitable to walk on without showing wear. Gradually more floor tiles are being applied to walls and this is no problem so long as the walls are strong enough to support their weight. However we do not recommend using wall tiles in floor applications.

Can I use any floor tile outside?

We recommend using a porcelain tile to ensure that the tile is frost resistant. The best tile for you to use outside in areas exposed to weather and rain, or around swimming pools is a slip resistant tile. There are 2 types of finishes to create the non-slip texture; a structured or sanded finish and these are tested for slip resistance rating. Although Slip-resistant tiles will be a little harder to clean its better then compromising safety. We do have a wide range of tiles which have both interior & exterior versions available if you are looking for a nice indoor, outdoor flow with your tiles.

Do I have to use small tiles in a small area?

No, there are no standard size rules. The common rule with tiles is the larger the tiles the less grout lines there will be which in turn will make the room look bigger due to it not being so ‘busy’ looking. The best idea is to look for the colour and texture of the tiles that you like rather than the size. But keep in mind if you have a tiny bathroom a 600x600 size tile will be a little excessive.

I want ‘GRIP’ tiles for my bathroom. Aren’t shiny tiles slippery?

It is what we do to tiles that makes them slippery. Soap or shampoo build-up can cause this problem. A stainless steel shower tray can also be slippery when build-up occurs. A degree of caution is always necessary i.e. use a bathmat. Remember that wet lino or concrete are also slippery. Choose a tile you feel comfortable with. “Grip” or slip resistant tiles are usually designed for outdoors and can be difficult to clean indoors.

What tiles do you stock at your showroom in Hamilton?

We keep stock of our Devon White Gloss and Matt 100x300 and 300x600 wall tiles. We also have a couple of 600x600 floor tiles in stock otherwise all of our stock is kept at our distribution centers and these can take up to one week to arrive once ordered.
If you need tile urgently we also have an area in our showroom with end of line and remnant tile specials that might be of some help.

How do I know how many tiles I need?

Most of our tiles are usually sold by the square meter, this means the area to be tiled needs to be carefully measured to work out how many square meters are needed. This is preferably done by your tiler, but provided your drawings are suitably detailed, we can work-out these areas from your plans. Please Note: There is always a level of wastage resulting from the cuts required to achieve your tile layout. This is best estimated by your tiler, but is approximately +10% for 450x450 tiles or smaller and +15% for 600x600 tiles. Remember that it is always wise to keep several spare tiles just in case replacements are required for any reason at a later date.

What are rectified tiles?

Rectified tiles mean the tile has saw-cut edges allowing for narrower grout joints between tiles and result in a stunning contemporary finished look. Rectified products have become popular. Please Note: Rectified tiles need to be installed on a square & level surface, and your tiler should be experienced with the requirements for laying this kind of product.

Do tiles vary in quality?

Tile manufacturers grade their products as they come out of the factory. Tiles On Devon only buy and sell first grade quality tiles and we stand behind our products 100%. Every tile carries a 10 year tile quality guarantee, when installed in accordance with good tiling practice, letting you choose tiles with absolute confidence.

Why do I have to use an underlay?

Underlay is used over wooden substrates and “locks” up your floor; stopping movement in the existing wooden floors which could cause the grout or tiles to crack. The best idea would be to call us so we can determine the substrate/joist spaces and establish if it better to use underlay or a speciality adhesive.

I am using Gibb Aqualine board, why do I have to waterproof?

Gibb Aqualine board is only shower proof and must have a waterproof membrane applied between it and the tiles. Please call us for more Waterproofing advice.

Can I tile on top of old tiles?

Yes you can tile on top of old tiles. The existing tiled surface and substrate will need to be in good condition i.e. no cracks, broken or loose tiles and a suitable substrate. Also a suitable adhesive will need to be used so please contact us for more information.

Will the grout lines go mouldy?

Our grouts have inbuilt mould inhibitors so as long as the wet areas are aired you won't have any problems. We do however, suggest that you seal all grout lines to assist in long term maintenance and to stop staining from the dyes in bathroom or kitchen products.
