Hi Guys

This is my 1st question on here and I've picked up loads of advice since joining, so thanks for that.

I have a job to tile a patio area with 800x600 porcelain tiles. It's triangular shaped and the right angle lengths are approx. 5m and 6.5m long. Although the area will have a roof over it, it will have open sides. The builders have put a fall on the concrete floor, that runs from the 90 degree corner to the the long side, to allow for water to run away (Approx 30mm fall over 6.5m length). The concrete will be dry, it's been down approx. 6 weeks already and job starts mid January. So my questions are:-

1) When I come to do the job I'm a bit unsure whether to put down an SLC as surely this could potentially lose the fall (If the SLC does what it says on the tin). What do you guys recommend?

2) I always use SBR primer for internal work, should I use the same for outside or do you recommend something else.

3) I use Benfer addy all the time and have had no problems with it, BenferFIX Rapidset would be what I would use for the job. Should I continue with this or use something else?

hi john.really have to ask tiling in outide area in january? dont you think it will be too cold?

It's not a problem. The customer has it all covered in tarpaulin and a heater giving us a temp. of about 25degrees to work in, so I'm not worried about temp. He will leave heater running until we are finished, cost doesnt sem to be an issue on this job

Hi John, does it need SLC'ng..? because not many SLC's can be used externally you know..?

Hi Dave

I think i will need to use upto a 20mm notched trowel to be on the safe side. I just wasn't sure if it was best to put SLC down but as you indicate about not many of them are suitable for outside. What do you think about the primer and addy selection?

Primer is ok to aid adhesion and min C2 adhesive will suffice.

Any deviations greater than +/- 3mm can be levelled in with adhesive first, allow to set and that will help with the tiling.

Its got to be right this one as its a barbecue project costing approx 40k. already done the walls, countertops and waterfall!!!! Will post some pics once its all done.

Look forward to them.
