Self levelling compoud

[TopTrainer]

Hi Guys n Girls
I have some slc work to do which i am quite comfortable with just have a couple of questions please

1. what are the advantages or disadvantages of latex based against water based I am intending the to use Ardex15, im not sure as yet at what depth.
2. Is it a good idea to apply it using a feather edge or a trowel if the later would you use a notched trowel or plastering trowel.
3. Would you still apply the same thickness of addy to an self levelled floor tiles are 8.5 porcelain

1. SLCs mixed with latex has better adhesive properties on certain substrates than many SLCs mixed with water, as well as being more flexible. In most cases, latex based SLCs are overkill, and in many cases, they're simply not suitable. Read the product specs for more info. The specs can differ alot between brands. Check my guidew (found in my signature) for a few pointers on what to take into account when chosing SLC.
2. The method of application depends on the SLC itself (viscosity), the thickness you're pouring it to, how the substrate looks, and what type of finish you're aiming at. For thin layers, an appropriate sized notched trowel or a spiked roller will proably work the best, if the substrate is already fairly even. For thick layers, or where the substrate is very uneven or very out of level, or if you want to build a gradient/slope, a plastering trowel or a similar tool will probably work better. I've personally never used a feather edge when applying SLC, but I don't believe it would be very practical.
3. The aim of increasing the thickness of adhesive is to improve the contact between the substrate and the tile, ie coverage. If the substrate is very flat, and the tiles themselves are very flat, you can get good coverage with a smaller sized trowel. If the substrate is uneven, or sloped, and/or the tiles aren't entirely flat, you compensate for that by increasing the amount of adhesive.

Check out the tile guide link in my signature for a few pointers on the use of SLC.

Two part makes it more flexi, Ufh and for any movement, Never used ardex15 so could'nt comment, Slc plastering trowel or spiked roller. Not sure what you mean by 8.5 porcelain but would use standard 10mm or more considering the size of the tile.

I use K15 all the time and it is a very good leveller....never cracks....if directions are followed.......Arditex ( latex 2 part) is good as well.....

iv used k15 lots of times its good gear quite easy to work with ,at this time of year with the warm weather i would wet the floor with a spray bottle or watering can to help adhesion especially if the floor has got the sun shining on it .i use a flooring trowel to spread it out after i have poured it onto floor as k15 is self smoothing and will need help to spread it out,iv used mapei eco plan which was supplied by a customer and found it a joy to use as it self levels itself you hardly need to trowel it

You're welcome

Whitebeam: Yeah, I do like to write a few sentances every now and then :lol:

ardex p51 primer is good to use prior to using K15........

yes dave i know i always prime but a couple of years ago i was talking to a ardex rep at ctd and he told me to wet the floor first as it improves adhesion in hot weather and reduces the air bubbles
