All portland based cementious products will allow water to pass through. The latex modified is more resistant due to the latex that is mixed in with the adhesive but that doesn;t make it “waterproof”. The latex also allows a bit more flex in the tile and substrate. As Jason described, thinset itself isn’t waterproof.
Beside this, what is a latex modified thinset?
Unlike unmodified mortar, which consists only of a blend of Portland cement, sand, and water retention agents, modified thinset includes additional retention products, such as latex polymers, which can increase its performance and strength.
Beside above, can I use modified thinset over concrete? Modified thinset, on the other hand, is not recommended because it relies on air to cure properly. It’s important to note that latex-modified thinset can still be used between the membrane and the subfloor because it is not impervious. However, unmodified thinset should be used between the membrane and the tile.
Then, is latex modified thinset the same as polymer modified thinset?
Mostly a difference in terminology. All thinsets that are latex or polymer modified with have add’l flex and shock resistance ; more so than the basic thinsets. In your case, any of the latex modified or polymer modified thinsets will work.
What is unmodified thinset used for?
Unmodified thinset is a blend of portland cement that’s mixed with sand (silica), and water retention additives, usually lime. Water is then added to the blend to create the final mortar. Unmodified thinset is also known as dry set mortar. This type of thinset mortar is best for ceramic or natural stone installations.

Can Thinset be used as grout?

What kind of thinset to use for porcelain tile?
ANSWER – Porcelain Tile should be installed with a latex modified thin-set or a polymer modified thin-set. The Custom Marble Granite Mortar I believe is a polymer modified thin-set. For larger tiles 12×12 or larger should use a 1/4″ sq. notch trowel.
Do you have to use thinset under cement board?
Since you are putting down hardie board on boards with small gaps, I would not recommend trying to put down thinset under it. It will make an enormous mess under the house (or whatever is under your bathroom). It is also more likely to make the floor uneven since it is hard to level thinset that is separated by gaps.
Is fortified Thinset the same as modified?
Latex modified usually refers to the multipurpose thin-sets that are 118.4 compliant that are mixed only with water. A latex fortified thin-set is a dry set (118.1) that is fortified with an additive (such as 317 mixed with 333 super flexible additive) that makes it 118.4 compliant.
How long does modified thinset take to dry?
The humidity, temperature and air flow in a room affect how long it takes to dry, but thinset generally is cured and ready to walk on or grout in 24 to 48 hours. Some installers and home specialists recommend waiting 72 hours for tiles applied to floors.
What is the difference between modified and unmodified mortar?
What is the difference between modified and unmodified thin-set mortar? Dry-set mortar is comprised mostly of cement, sand, and a water retention agent, and is also called unmodified mortar. Modified mortar contains a polymer which can improve the bond strength and add other properties.
Can I use modified thinset on Kerdi?
Modified thinset mortars aren’t recommended for use with Kerdi because they must dry out to gain strength, whereas the membrane inhibits drying, which can lead to unpredictable results. Schluter’s recommendation is to use unmodified thinset mortar when installing Kerdi over most shower substrates.
