Ok so, some of you know I’m a new learner and to take my experience further i rung a ‘professional tiler’ to see if i could do weekends to learn the trade basics.

My first question for him was ‘how does he stick his tiles on the wall, trowel it or blob it(dot n dab)

His answer ‘blob’

I question why he uses this method and he said because if walls are uneven it gives him movement, so i said that it would have unwanted voids behind the tiles and couldn’t it cause water damage / tiles not stick correct? , to which he replied ‘no water should get past tiles and grout anyway’

So how can i tell him that he shouldn’t dot n dab and that i also won’t be working with him! Haha!

With the exception of the age old sand:cement fixing method, with modern techniques and materials its always been bad practice. But since the recent updates, Spot fixing or dotting 'n' dabbing is now officially wrong as per British Standards.

1. Cement grout is water resistant, not waterproof so water will get though and wreak havoc on the adhesive and any non-waterproof substrates. ready mixed adhesive and to a lesser extent cement based adhesive can weaken under constant exposure to moisture.

2. Can get nasty mould growth in and behind the tiles

3. Less contact with the substrate and tile means drastically reduced bond strength which can lead to shearing under movement

4. Voids are weak spots so tiles are open to cracking from water and temperature fluctuations.

5. If the wall is so far out, fix the wall before installing the tiles.

6. Anyone who spot fixes are either trying to cut costs on materials, wrongly educated, or lazy.

I agree, if you are starting out then making enemies with already established tradesmen in your area will not be a good idea.

I’ve seen crap work done by plenty of trades folk. I’ll often go into someone’s house who’s had their previous bathroom done by someone else and I get asked what I think. It’s far easier to just nod and say it looks good than anything else.

Make sure your own work is spot on and that’s all you need to worry about. When it comes to explaining to the customer why you’re the man for the job, simply list out what you do. They can make an informed choice based on the information you have told them or listed out in your Quotation.
