Dot and dab tiles.....ohhh! - TilersForums.com

[Fitwidge]

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.

Sadly from my experience there is a large portion of tilers out there who do it.

If you’re not going to work with him, don’t worry, call someone else.
He won’t take your advice kindly and probably won’t change his ways on the day so if someone who rang up for him to teach.

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

We had a guy come in shooting his mouth off that was probably over ten years ago . Still no one wants to know him .

That’s the thing, just put your energy into doing what you do well.
Forget what others are doing and see it as potential future work when it all fails.

Don't turn up Monday morning and when he rings you say you've blobbed.
