I'm about to start laying insulation UFH and tiles on concrete base using Ultra Proflex SP. The blurb says a "solid bed trowl" method should be used.

What exactly is this? I always thought using a notched trowel was the defacto method for laying boards and tiles.

If it is what I think - just a flat layer of adhesive, doesn't that make it harder to level the tiles?

Thanks in advance

hi what is ufh? as for a soild bed trowl its 20 mm notched trowl that gives a solid bed when the tile it hamerd in to it hope this helps

Solid bed trowel is a trowel, usually round notch, that when the tile is pressed into the adhesive, pushes the adhesive down to give a complete coverage of the tile/substrate.

Indeed it was Top Tiler, I was just repsonding to the thread starters post.

Thanks guys - all clear now.

Why don't they just say "use a 20mm notched trowel"?? - Tiler speak I suppose

I'm not big on trowels but the notch being 20mm and greater than the tooth about 6mm gives the solid bed

There are other trowel designs available that give a solid bed but don't have a round notch.
