One DIY job which I hate is applying sealant round the edges of worktops / sanitaryware etc.

On the face of it, what could be simpler - but getting a thin, uniform bead always seems to evade mefrown

I've tried masking tape and various finishing tools, but these often make matters worse! Is it just a case of practising and having confidence?

Run your sealant around area,get a spray bottle fill with water and washing up liquid,spray around tiles and over sealant(sealant wont stick to the washing up liquid).Get a lollypop stick with a curved edge,press lightly on sealand and run along sealant.So easy.If you are doing the bath,make sure you fill it up with water and leave overnight.

I tend to pick up some new tips and tricks for sealing every time I do it.

Make sure the surface is as clean as possible, so use a clotch and white spirit/turps to get off any unwanted muck and dust.

Make sure you only use the minimum amount of sealant. If you use too much, its much harder. If the gaps are bigger, then maybe do a few runs with the sealant gun, but wait till the first run is dry first.

As for the smooth finish, I've always used a wet finger combined with a bit of toilette roll. Seems to do the trick.

Its worth experimenting with brands too. Some are better than others. Think I had bit more success with unibond vs Screwfix own brand.

I finished the tiling in my kitchen recently and that looked fine.

I use something similar to these (bought mine in Lidl IIRC sometime ago): http://www.screwfix.com/p/no-nonsense-smoothing-to...

Also as mentioned buy good quality sealant.

Applying sealant/caulk/etc. was once I job I feared now it is so easy. Put a decent bead of it down carefully with the gun, then simply run the tool over it wiping away the excess as it build up. Perfectly smooth sealant and no mess.

1) Buy decent sealant
2) Buy a decent gun
3) Have correct tooling stick for application
4) Cut nozzle at correct angle cleanly, no burrs on tip
5) Make sure there are minimal obstructions that will stop you moving with the gun
6) When tooling spray solution onto tool, not the sealant.

If you have applied the sealant well , tooling should be minimal.

Small bead, cup of water / fairy, dip finger in and wipe along occasionally it will stick to your finger - simply wipe off and carry on - any tool removes feel.

If you made a splodge, turn your hand over and use a finger nail to remove it.

Dow Corning is best sealant imo

Use masking tape above and below the gap being sealed and remove whilst sealant is wet, after you have smoothed with wet finger / lollipop stick / other. This will give nice crisp lines..

I use tape and Unibond sealant. Never a problem, just pull tape off, back on itself as soon as you're done. Don't let it dry/set too long

And as its your first time, a couple tubs of Wonder Wipes.

confused That bath looks pretty useless to me, it hasn't got any taps - why would you even bother sealing it?

As said, mask it, apply a uniform bead of decent silicon, wipe with wet finger.

Agree, apart from not spraying water on sealant.
We spray both, the point of the water is to stop it sticking to areas you don't want it to, even with a new Fugenboy you can get a smear if done dry.
