What is the difference between a bathroom renovation and remodelling? 

Renovation and remodelling differ depending on the scale. Renovation is done at a smaller scale. That is, replacing tiles or a bathtub or something else. But, remodelling is at a larger scale. It is when you change almost everything. A bathroom remodelling project is a bathroom renovation with some twists.

What can be changed in a bathroom renovation? 

First of all, you can change the tiles in your bathroom like porcelain tile, ceramic tile, and natural stone tiles to give it a new look. Other than that, for a bolder change, you can change fixtures like sinks, bathtub and even showerheads. For a low budget but effective renovation, change the setting of bath and sink and other decorative pieces. The lighting of the bathroom also plays a significant role. 

Can I make my small bathroom look bigger? 

A white theme will help you achieve it. It is not easy to build new walls every time. This is where white colour comes to your rescue. White colour reflects all the light that falls on it and creates an open, bright space. This creates an illusion of lack of boundaries, and this makes all the difference. Use natural white light and whitish tiles, etc. and achieve the desired effect. 

What type of tiles proves best for a bathroom? 

Glass, Porcelain and stone tiles prove the best for bathrooms as these are low absorbent and look great at the same time.  

Can I re-glaze my bathtub instead of replacing it? 

To cut short, re-glazing is a budget-oriented best move and replacing is a quality-oriented best move. Although, many old tubs are made of cast iron, which is a sturdy material and are deeper too. But re-glazing lasts approximately three years depending upon the usage. All said, buying a new tub is costly, but it looks the best. 

Is an exhaust fan necessary? 

An exhaust fan is a must in bathrooms and is an easy way of protecting your bathroom from mildew and mould. Also, it takes out the bad odour and keeps the bathroom air fresh. So, do insist on setting up an exhaust fan. 

Is Will replacing the tile shower be a costly affair? 

Yes, replacing a tile shower is very costly because you not only add tiles to it but also treat the area with waterproofing which involves first the levelling and then waterproofing. Thus, take care to do it cautiously and strictly according to Australian standards, because it is very costly to replace it. 

What do you mean by screed? 

Screed is usually sand and cement mixture that is applied over concrete or sometimes underfloor heating. This should be done to provide a smooth and levelled surface on which further work like tiling can be done. 

What ingredients make screed? 

The screed can be made up of sharp sand and cement to make an excellent screed and with coarser sand of the range of 6-10mm and cement to make industrial screed. 

Why is screed laid? 

Screed covers an uneven or rough sub base and covers the concrete layer or heating pipes. This lays the foundation for an even surface for carpeting or tiling. This is necessary because a correctly done surface should not differ for more than 5mm over a 3-meter length. 

What are the types of screed? 

There are four types of screed- Bonded Screed, Unbonded Screed, Floating Screed, and Underfloor Heating Screed. 

What are the difference between concrete and screed? 

Cement and screed both have the same ingredients. But, the difference is in the texture. Cement is made up of coarser sand and has more sturdiness and durability while screed is finer because it is made up of more beautiful sand and is used for giving a finish and doing levelling. 

How many days does the screed take to cure or dry? 

Screed is cement, so it takes about 28 days to cure fully. But you can walk on it after one or two days. Also, you can start moving furniture after 5 to 7 days on it. But to gain full strength, it is best to let it cure for a full 28 days before starting to work on it. Although using additives can quicken the process. 

When can I tile over screed? 

As said above, screed takes a full 28 day to cure correctly. And any tiling project should be started after that only because screed can shrink during the curing period. Thus, for best results, it is better to wait till then. 

How to remove white mineral buildup in showerheads? 

It can be quickly done at home. Simply take a sandwich bag and fill it halfway with white vinegar. Now tie this sandwich bag to the showerhead, such that the whole shower head is immersed in vinegar. Leave this set up overnight and the next morning, untie the vinegar bag and clean the residual mineral by a toothbrush. This process will leave your showerhead new and shinning. 

How can I keep my drain clog-free? 

Some simple measures that we can take are, watch what goes down the drain. Buy a drain strainer that will help stop all the bad stuff from going down it. When such stuff does not go down it, it will not clog also. Also, avoid using caustic chemical drain cleaners too much. Because in the long run, they may affect the pipe quality. Instead, you can pour one cup of baking soda followed by hot water regularly. 

How should I unclog my grout filled bathtub drain? 

This is a severe issue. It is not easy solving this issue, and you might need professional help because the drain may require to be changed. But before calling for help, you can try removing the trap for the bathtub and snake the pipe. If that doesn’t work, you need to change the pipe. 

What to do if water pressure is low? 

If the water pressure is low, then first check all the faucets and filters for clogs. These need to be replaced annually. Also, if your drains are galvanized metal ones, then calcium deposition on the insides of the pipes happens, and this clogs the drains. In such situations, you need to change the whole drainage system. 

What do you mean by waterproofing? 

Waterproofing is the act of cladding with a layer of waterproofing membrane and other components in the proper sequence to make surfaces waterproof. This is done in bathroom walls, backsplashes, pools, spa, laundries, toilets, exterior walls, etc. This prevents leakage and moisture buildup. 

Why does waterproofing fail? 

Waterproofing fails because not all components are correctly installed. Sometimes, primer or bond breaker is wrongly applied, or an incompatible tile adhesive or sealant is used. Waterproofing is a complex subject; therefore, it needs to be perfectly accomplished. 

Which substrates can waterproofing be applied over? 

Waterproofing is ideally for screed and concrete. But it can also be applied on structural plywood, wet-area plasterboard, render and existing tiles, composite timber sheets, blockwork, and fibre cement sheet. 

What do you mean by a primer? 

A primer is a liquid that is applied before the waterproofing membrane is applied. Primer helps waterproofing membrane bond with the underlying substrate. Without a primer, waterproofing can fail. This primer is usually made of latex, epoxy, polyurethane. 

What does a primer do? 

A primer means longer curing time for the concrete, and this is good for tiling above. Also, the adhesive applied on top of the primer stays wet for a longer time. Thus, there is more open time. Also, primer results in lesser pin holding in the waterproofing membranes. 

Is primer necessary before waterproofing membrane application? 

Yes, it is very much needed. Some of the benefits of applying primer are that waterproofing membrane can now hold the substrate better. Also, it seals the dust particles on the substrate and aids in low pin holding. 

Is primer necessary after waterproofing membrane application? 

No, primer need not be applied over the waterproofing membrane as it is not water-absorbent. Thus, unnecessary there. But otherwise, primer is necessary on every other substrate, and you may void the manufacturer’s warranty if the primer is not applied. 

What is a waterproofing bond breaker? 

You cannot avoid building movement. Waterproofing bond breaker uses the elastic properties of the waterproofing membrane to accommodate the building movement. In other words, it manages the effects of building movement over the waterproofing membrane. 

Where should I apply waterproofing bond breaker? 

According to Australian standards, waterproofing bond breaker is necessary for internal corners and joints etc. to accommodate building movement. 

What do you mean by a porcelain tile? 

Porcelain tiles are made up of porcelain and added minerals. They are very durable, water-resistant, and very dense. Porcelain tiles owe these properties to the raw materials used and the high temperatures they are baked at. They are baked at 1200 Degree Celsius. Thus, porcelain tiles are great for commercial purposes and high traffic. 

What do you mean by a ceramic tile? 

Ceramic tiles are made with clay and fired in a kiln. But these are baked at lower temperature and are not as dense as porcelain tiles. Also, these tiles are more water-absorbent. And they are thus more preferred for household tiling projects. 

What do you mean by a vitrified tile? 

Vitrified tiles are extremely water-resistant tiles. They are made up of clay mixed with quartz, feldspar, and silica. Vitrified tiles, in addition to being water resilient, have a glossy finish and are scratch-resistant too. 

What is the process of laying tiles? 

Firstly, levelling and screeding and then perform waterproofing over it. After waterproofing, apply adhesive, and the do tiling along with the spacers. After laying tiling, remove the spacers and do grouting in these spacings. Lastly, apply sealant if necessary. 

What is grouting? 

When you fill spaces between tiles with grout, it is called grouting. Grout is usually made up of water, sand, and cement. Many types of grout are there, epoxy grout, unsanded grout, etc. The purpose of grouting is to accommodate building movement and movement in tiles. 

What do you mean by additive? 

The additive is a performance enhancer. It is added to grout as well as adhesive. By adding it to grout or adhesive, you can make grout more resistant to stains, water, and chemical reaction. Also, it can level up flexural strength and bond strength. 

What is the meaning of tile adhesive? 

Tile adhesive adheres the tile to the surface below. Tile adhesives are either cement-based or pre-mixed. Pre-mixed is standard while cement-based gives you more flexibility and adaptation to the surface exactly. Choosing the correct tile adhesive depends on various factors like area, humidity, temperature, and the type of tile being laid. 

How does low humidity affect cement-based adhesive? 

Low humidity results in a shorter life of tiles, as, low humidity causes water from the adhesive to evaporate faster. But, cement needs water to form better bonding. With a lack of water, bonding is not proper and thus the shorter life. 

How does high temperature affect cement-based adhesive? 

Cement-water reaction is faster at high temperature. And when this reaction occurs faster than necessary, the cement crystals made are smaller than when the reaction is usually paced. Any temperature above 35 Degree Celsius is not favourable for tiling. 

What special measures should be taken when doing exterior tiling? 

Exterior tiling goes through more rough usage due to thermal expansion which interior tiling doesn’t experience. Thus some special measures need to be taken like adhesive should contain additives and adhesive should be applied in liberal quantities. Also, tiles should have a mechanical fixing every 2 meters.  

What special measures should be taken while installing large format tiles? 

Any more prominent tile or of the range of 600mm x 600mm is termed as large format tile. Some special measures required for large format tiles are, the adhesive used must be rapid setting also, since larger tiles can be bent in between thus adhesive needs to be applied at the back of tiles too. Lastly, the joints in case of porcelain should be minimum 3mm, and in case of the ceramic should be 5mm at least.
