Not only should you not be concerned about gaps in the mortar beneath your tiles, but you should be concerned if there are not gaps! Mortar is applied to the substraight and to the back of the tile with a notched trowel.
Can you put too much mortar under tile?
An excess of thinset can cause an uneven surface, ooze between tiles, and form a poor bond between tiles and your substrate. Use just enough thinset mortar to form a solid bond between the back of the tile and the surface beneath. In most installations, a layer of thinset 3/16 to 1/8-inch thick is sufficient.
Should there be a gap between tile and wall?
The Tile Council of North America recommends at least a quarter-inch gap between the tile floor and the walls. Never fill this gap with grout, because tile grout is not flexible. Instead, fill it with an elastic material capable of sustaining the movement of the floor and the movement of the wall.
What consistency should mortar be for tiling?
thick peanut butter
The mortar should be fairly thick, like thick peanut butter. The thickness and consistency of the initial mix should be the same consistency of the final mix. Slaking is necessary! Do not add more water or mortar mix after the mortar slakes.

How thin can mortar be applied?
The terms thinset cement, thinset mortar, dryset mortar, and drybond mortar are synonymous. This type of cement is designed to adhere well in a thin layer – typically not greater than 3/16th thick.
How thick is too thick mortar?
Mortar Thickness
The building code for weight-bearing brick walls calls for mortar to be no more than 3/8 inch thick. The thickness of the mortar can vary in other types of structures from 1/8 inch to ¾ inch, according to the MC2 Estimator’s Reference website.
How do you fix a gap in a tile?
Quote from the video:
Quote from Youtube video: It's all about lining up the tiles just just exactly the way you want to have them lined up. And it's also about the pattern. And what I have to worry about here is my pattern.
What is the standard gap between tiles?
Common practice is 2-3mm for wall tiles and 3-5mm for floor tiles.
How wide of a gap can you grout?
For cementitious grout, joints smaller than 1/8″ generally should only be grouted with unsanded grout, and joints of 1/8″ and larger should only be grouted with sanded grout. Joints larger that 3/8″ usually need a more heavily sanded grout to accommodate the large joint.
How do you avoid common mistakes in tile?

- Grouting too quickly or unevenly. …
- Adding dots of adhesive to tile corners. …
- Using the wrong adhesive. …
- Avoiding the use of battens. …

- Letting excess grout stay. …
- Miscalculating the needed number of tiles.
Should I wet the tiles before laying?
The main idea behind soaking or wetting tiles before installing them is that the base of your tiles is porous and therefore has a lot of air inside. If you lay dry tiles directly on top of mortar or cement, the tile will stick initially but as time passes, it will most likely fall off.
Is Lippage tile normal?
There are tolerances for tile lippage. The ANSI A108. 02 standards say that acceptable lippage for floor tiles with a grout joint width of 1/16″ to less than 1/4″ is 1/32″ plus the allowable inherent warpage of the tile.
How thick should a mortar base be?
For the bottom layer of blocks, spread a layer of mortar about 12–15mm thick and a little wider than your blocks onto the concrete foundations. Make lines in the mortar with your trowel — like this: Place a block onto the mortar and gently tap to get the height, position and level you need.
How thick should mortar bed be?
With a standard thinset the maximum bonding thickness should never exceed 3/8 inch. If something is classified a medium bed mortar it is typically good for a maximum bonding thickness of ¾ inch.
What should the consistency of thinset mortar be?
creamy peanut butter
What is the proper consistency for thinset? When thinset is mixed properly it should be the consistency of creamy peanut butter. What happens if you put too much water in thinset? If thinset has too much water in the mixture, it will be too thin and squish up in between the tiles when they are laid into place.
How do you know if mortar is right consistency?
Properly mixed mortar ready for use should have a consistency comparable to thick peanut butter. Test its thickness by seeing how it adheres to the trowel or mixing paddle. Scoop some of the mortar onto the tool and tip the tool 90 degrees. If it falls off immediately, the mix is too thin.
What happens if thinset is too dry?
Too dry: the thinset is stronger but suction bonding to the tile is poorer. Too wet: the thinset is weaker and may crumble under load, however, suction bond between tile and thinset is generally greater.
How thick should my thinset be?
3/16th inch
The terms thinset cement, thinset mortar, dryset mortar, and drybond mortar are synonymous. This type of cement is designed to adhere well in a thin layer – typically not greater than 3/16th thick. For example, a 3/8″ notch trowel will produce a 3/16th inch thick coating after the tiles are pressed in to the cement.
Is back buttering tile necessary?
Although not necessary for tile coverage, back buttering can be effective by increasing the bond of the mortar to the back of the tile which is an excellent benefit.
Can you layer thinset?
You can put new thinset on top of old, but only if the old thinset is perfectly smooth and level. This is rarely the case once the old tiles have been removed. The best option to smooth out the old thinset and prepare it for new tiles is to grind it down.
