Large format tiles have become very popular for use in kitchens, bathrooms and open plan living areas.
This is because;
They have fewer grout lines resulting in a neater finish, which works really well with a modern interior.
They can help give the illusion of less visual clutter in smaller rooms. If the same flooring is used throughout adjoining areas this can really help.
However, these big tiles can cause issues.
Any slight errors can cause issues due to there being a larger area.
Start with the layout, not the adhesive
Before fitting any tiles you should consider how you will lay them.
When using large tiles around doorways, kitchen islands and room edges you can end up with some awkward cuts.
If you don’t plan how you are going to fit them you could end up with a small strip of tile along the most prominent wall.
This can cause issues with the appearance of your tiles.
Think about the direction of the tiles, where the grouting will go and how the pattern will flow between rooms.
Using a sample of tiles to dry lay or setting out your tiles in detail will help you see if there are any issues.
You can also ensure your tiles look good in the lighting of the room.
Flat floors are more important than ever
A key issue with large format tiles is making sure you have a flat surface.
Even small issues can show when using larger tiles. One side of the tile may be slightly higher than another causing lippage.
Not only does this cause issues with appearance but can also be uncomfortable to stand on and more prone to breakage.
Depending on your floor you may need to level it.
Trying to cover major issues with too much adhesive won’t help.
The flatter and more even your background surface is, the easier it will be to get an even finish.
Choosing the correct adhesive system
Large tiles can introduce different requirements, particularly when working with dense porcelain or natural stone.
The adhesive must suit the tile, substrate and installation environment.
When planning the work, guidance from specialist floor adhesive manufacturers can help identify suitable products and the relevant application requirements.
Adhesive coverage is especially important with larger tiles.
Depending on the system, installers may need to use particular trowel sizes and techniques to achieve the required bond.
The manufacturer’s instructions should also be checked for mixing, working and curing times.
Choosing a suitable product is only part of the process. Correct application matters just as much.
Underfloor heating adds another consideration
Tiled floors often go hand in hand with underfloor heating. However this can cause issues.
The heating and cooling can cause movement in the floor.
Ensure you are using the right products for your fitting by following the relevant guidelines. You should also ensure the heating is set up and used correctly.
Don’t try to speed up the curing process by turning the heating up straight away.
This can cause issues.
If you take your time when fitting you can avoid any damage which may be expensive to fix.
Handling larger tiles requires care
Large format tiles can be difficult to move, cut and fit. Some may require specialist equipment, cutting tools and extra people.
Trying to lift and fit oversized tiles without the right equipment can cause breakages and possible injury.
It is important to ensure you have accurate cuts around sanitaryware, pipework and kitchen fittings.
When ordering you should allow for some wastage. Especially if you have a complex design.
Trying to save money by ordering the least amount can cause issues if one of your tiles breaks and you have to wait for your project to be completed.
Don’t forget the grout and movement joints
Although there are less grout lines it is still important to ensure you have consistent joint widths. This helps with the appearance of your tiles and ensures they can be fitted properly.
Ensure you include movement joints where needed.
This can be easily overlooked when choosing your tiles from a showroom or photo. However it is an important factor.
The best results come from preparation
Large format tiles can give a great finish however they can cause you to think a bit more than you may expect.
Once you have chosen the right colours and sizes, having a planned layout, correct substrate, compatible adhesive and careful fitting will all help.
If you get everything right you will find it much easier to get a clean, modern finish.
