Revamp Your Space: Can You Tile Over Wall Tiles in a Bathroom Effectively

Preparing for a Successful Overlay

Once you are done with the thorough inspection of the existing tiles, it is time to prepare the old tile surface for a new layer of tiles. Laying new tiles on the existing tile floor or tile wall needs a properly prepared base. The new tile layer will not be stable until you give it a firm base. Here are important steps to prepare a stable and perfect base on the existing tiles for laying new tiles to make your bathroom renovation stand out:

Deep-Clean the Original Tiling

The first step in preparing the firm base is a deep cleansing of the original tiles. Be enthusiastic about getting a clean and clear surface of your old tiling. You can use Trisodium Phosphate, known as T.S.P., for deep cleansing of tile floors or tile walls. Take a brush and a degreaser liquid; rub the original tiles until you witness a clean, clear, and fresh tile surface.

You need to sand the tile surface slightly after proper cleansing. It is necessary to create a moderately rough texture on the surface of the old tiles. Ensure a clean and nicely prepared tile base is used to lay the new tiles to get a successful tile overlay. 

Apply the Right Bonding Agent

Well, now, the old tile surface is entirely prepared. It is time to apply for a high-quality bonding agent. You can use a high-quality bonding primer, like ECO Prim Grip. It is the best option to provide the utmost stability to the new tiles. Suppose you are working with ceramic tile; precisely follow the below-given steps for making the application of the bonding agent step flawless: 

Use 100-grit sandpaper to roughen the tile surface properly. You must have an appropriately sanded texture to make the adhesion firm.

Next, apply the bonding agent. Strictly follow the instructions of manufacturers in the application process.

Let the bonding agent dry well before laying tiles over it.  

The Art of Laying Tiles over Tiles 

Well done for preparing the original tile as a flawless base for laying new tiles. The next step works as the most important staircase leading towards a successful tile overlaying. The existing tiles are now all ready to receive a new, elegant look. 

Are you getting confused about where you should start tiling? What adhesive will work best for your project? What is the right method to lay a tile over the existing tile? How should you apply grout? No need to worry about these questions. We have answered all these questions in detail to help you learn the best way to lay tile over tiles perfectly. Laying tiles over tiles requires precise and careful planning and application steps, and a calm temperament is needed to use the techniques correctly. Here we go:

Starting with the Right Adhesive

You must choose a high-quality adhesive to lay new tiles over the old floor firmly. The adhesive must share a durable and stable texture so new tiles may stay over old tiles longer. The strong bonding of the new and old tiles will make your bathroom wall tiles look precisely beautiful and cohesive. You can opt for thinset Mortar. It is a favorite with designers and homeowners for its amazing ability to provide a balanced level to uneven tile surfaces, and it wonderfully resists moisture and mold.

Be careful while applying thinset Mortar. You must have the right trowel size according to the size of the tiles to apply an equally adequate layer of thinset Mortar over the tiles. You can use the ‘back butter’ method to apply thinset Mortar to large tiles. In this method, you first apply thinset Mortar on the old tile surface and its thin layer on the backside of the new tile. The back butter method has an extra layer of thinset Mortar to ensure that large tiles are strongly attached to old tiles and do not loosen sooner.

Positioning New Tiles

It is time to lay tile over old tiles precisely. First, choose a starting point. In the case of laying tiles on a bathroom wall, you need to measure the wall first. Measure all the fixtures on the wall to cut tiles accordingly. 

Tiling over bathroom wall tiles is a little bit of a tricky task. It would be good to take a wooden baton and fix it horizontally at the below part of the wall or at the intended starting point. Start installing tiles above the baton to ensure a straight tile row. Press the tile over the adhesive firmly and slightly twist it to form a strong bond between the old and new tile. You can use a rubber mallet to press tiles. You must use a level to make tiles stay in a straight row. Start laying tiles from the center and move outwards. Hence, the trimmed tiles will be positioned in the corners to create a seamless, neat tile layout. 

You must use a tile spacer to put equal gaps between all tiles. Apply the rule, ’measure twice, cut once,’ to avoid wasting tiles and creating a mess. It would be good to purchase ten percent extra tiles. It will make your tile installation more precise in case of wastage, breakage, or chipping of tiles. Extra tiles will prevent any disorder in the intended design and color scheme. 

Grouting for Longevity

Once you are done with laying tiles all over the wall, it is time to apply grout in spaces between tiles to ensure the durability of your new tile wall. Grouting is necessary to make your tiles stable, and at the same time, it adds a neat, aesthetical charm to the wall layout.

Carefully fill grout into all gaps between the tiles. Make sure there is an even quantity in all spaces. Use a wet towel to wipe off extra grout over the tiles. You must follow the instructions on the packaging to complete the grouting flawlessly. Let the grout dry before applying sealant. Apply a high-quality sealant to make grout resist moisture, dirt, and stains.
