scottishjohn Posted February 6, 2019 Share Posted February 6, 2019 ice cubes make good sealer bead shaping tool--make your own shape used to use them for sealing on doorskin replacement--don,t stick to anything loads of tile levelling systems example https://www.vitrex.co.uk/products/lash-tile-levelling-system/ loads of similar systems -- u tube even has videos comparing different systems 1 Link to comment Share on other sites More sharing options...
Onoff Posted February 7, 2019 Author Share Posted February 7, 2019 (edited) I have to run a bead of sealant where the wall tiles come down and meet the floor. The wall tiles sit nominally 1mm off of the floor tiles and the gap has been rammed with grout. First step will be a line of clear CT1 at that junction. When set I'll apply a bead of silicone, probably grey, but how to do this neatly? How big for a start should the bead be, 5mm? More? A rough plan was to say mask 1/4" from the floor and the wall, silicone it, tool the excess off then peel the tape off. Sound like a plan?

Onoff Posted February 9, 2019 Author Share Posted February 9, 2019 (edited) A problem..... The right hand grout joint of the mitre is quite wide. I've got cracks in there as shown below. I half worried about this as I've ply behind the mitre. I figure it'll expand / contract at a different rate to the wings either side where there's no ply. The mitre joints btw were taped and tanked. Do I re grout, CT1, white silicone? Cheers Edited February 9, 2019 by Onoff Link to comment Share on other sites More sharing options...
bassanclan Posted February 9, 2019 Share Posted February 9, 2019 I know we had this discussion before, but where there might be movement e.g. between a brick and a stud wall etc I miss out the grout and fill with the appropriate colour ct1. I need the job to last at least 5-10 years. I know the colour of the CT1 grey has already been derided, but this is a job I just did. Dip your finger in solvent (or in my case turps) instead of washing up liquid and it stops it sticking to your fingers. The problem I have encountered with clear (and whit) ct1 is it seems to go yellow quickly. In the meantime I suggest https://www.screwfix.com/p/pro-grout-rake-cutter/17903?tc=AT3&ds_kid=92700022888056172&ds_rl=1241687&ds_rl=1245250&ds_rl=1244066&ds_rl=1248184&ds_rl=1245250&ds_rl=1247848&gclid=EAIaIQobChMIuoWn5bSu4AIVxR-GCh33nQwxEAQYASABEgLi6fD_BwE&gclsrc=aw.ds Link to comment Share on other sites More sharing options...
Onoff Posted February 9, 2019 Author Share Posted February 9, 2019 I can't really be raking grout out for fear of going through the tanking just behind. It's got to be something that goes over the top. Link to comment Share on other sites More sharing options...

Onoff Posted February 9, 2019 Author Share Posted February 9, 2019 Setting up for a hopefully neat silicone bead where wall meets floor. Tried masking to a 7/8mm tile first but figured that'll look too wide across the "flat": Very impressed with Frog tape in comparison to ordinary masking tape. Re did with a 5mm pack. I'll now run a very small bead of clear CT1 along the joint keeping it clear of the tape. When dry I'll go over with silicone, probably Mapei grey depending on how it looks.

With hindsight etc! Going to persevere with this perimeter wall/floor joint as I am and see what it looks like. Link to comment Share on other sites More sharing options...

bassanclan Posted February 9, 2019 Share Posted February 9, 2019 No taping on the above, just wiped where I veered off course. When you use tape you generally get a ridge when you pull the tape off which you either have to smooth back (in which case why bother with the tape) or the ridge is where water and therefore mould collect. As you're not doing it every day, but quite a bit to seal you might be better of using a fugi tool. Have a look at you tube for some videos, I've not tried it with ct1 as it's so bloody sticky, but it makes trowelling silicone sealant easy.

Onoff Posted February 9, 2019 Author Share Posted February 9, 2019 Well that came out like crap after trying to tool it. Wiped it all off in the end. Link to comment Share on other sites More sharing options...
Mr Punter Posted February 9, 2019 Share Posted February 9, 2019 CT1 is a pain to get a neat finish with and it discolours. If you use masking tape you have to have a bead a fair bit narrower than the tape gap. Just use the tape to stop the smearing being too excessive. It looks a lot of silicone in there. Do you have a pic of it after tooling? Link to comment Share on other sites More sharing options...

scottishjohn Posted February 9, 2019 Share Posted February 9, 2019 (edited) you have not cut the nozzle correctly --far too big and wrong shape .thats the problem try cutting some of your other spare nozzles into different shapes and much smaller -try them on waste bit of board --no tape --just get the bead right size before wasting anymore on the real job- tape should not be sealed over by choice -its just going to give hard thick edge of sealer when you remove it. its a safety edge so you can smear it in right shape and excess goes on to tape, but there should be no measurable thickness on tape right close to sealer ,so when removed you don,t end up with an edge shape should have finished before getting to tape ideally . If you want to keep working it ,wet your finger or use ice cube like i said before,if you don,t it will skin too quick +pull Edited February 9, 2019 by scottishjohn Link to comment Share on other sites More sharing options...

What type of gun have you got? Looks like you've been pumping a lot which would suggest a cheap one to me. Try moving faster ( I know it's easy for me to say) but it will leave you with less ripples amd generally give you less excess to deal with. Mastiking is a bitch at the best of times ( behind taps are the worst). You need to work quick and tool it as soon as possible. Try again but maybe start on a nice short straight run, not around a curved toilet ? 1 Link to comment Share on other sites More sharing options...

Gone West Posted February 9, 2019 Share Posted February 9, 2019 I used to use masking tape and a flat blade screwdriver until I got a Cramer Fugi 5 piece kit. Although it's still tricky to use if I'm trying to do a basin behind a tap. https://www.ironmongerydirect.co.uk/product/cramer-fugi-applicator-kit-5-piece-711919 https://www.youtube.com/watch?v=GBT3kvbocbc 1 Link to comment Share on other sites More sharing options...

Even these in the hands of someone competent should do the job I'm sure. As soon as the grey is dry I'll rip it out and try again taking on board all the above. 1 Link to comment Share on other sites More sharing options...
Gone West Posted February 9, 2019 Share Posted February 9, 2019 I think the shape of the Fugi one with the chamfered back that is what makes it relatively easy to use. 1 Link to comment Share on other sites More sharing options...
