dot and dab. . . . .

[lurch]

I do some sub contract work for two different contractors. One of which insists on using capping in dot and dab buildings, the other does not. Who is correct?

personal preference

Here's a stupid question: Why is it called 'dot and dab'

 

[roukel01]

I always think it looks like a better job with capping/oval tube, however, it is as already mentioned personal choice.

just to expand. . . . the contractor that uses caping insists there is a reaction with the dot and dab adhesive and the cable pvc, hence capping.

Apparently the plaster does react with PVC but IMO its the save as the suns effect on PVC not enough to worry about. He who pays calls the tune.

I've yet to see a property that doesn't have twin + e clipped outside to feed outside lights.

Capping is there to protect us from the dreaded spread's trowel, or if you'd believe a spread who I recently told this to who's 'done all the electric qualifications':
"Capping is for when people do DIY when they are drilling in a wall if white stuff comes out they will stop drilling" I nearly wee'd myself.

laymans term as the idea is you put dots and dabs of adhesive on to stick it as opposed to fully covering the wall

yes the capping is one reason to protect from the trowel. . . but there is no trowel with dot and dab is there .. .

The spreads are a witty bunch, aren't they.....

No point in using it then, no?

thing longer down the line guys...

when you or A.N Other electrician needs to replace the cable, will he (or you) be happier fishing new twin in using the old as your fish down oval tubing or capping, rather than slicing the wall open to access a cable thats moulded in with the board adhesive??

Also (to the best of my knowledge) board adhesive does not interfere with T+ E whatsoever, but the older method of scratch and skim (thats sand/cement mix prior to skimmed finish) does attack T + E cuasing detrimental breakdown of the outer PVC coating.
