Can you mix cement with thinset?
Portland cement is used in thinset to provide the bonding mechanism; sand is added to temper the cement; and a liquid latex mortar additive is added to give the thinset pliability, allowing the materials to expand and contract without cracking. You can make your own thinset by purchasing these items separately and combining them.

Is Versabond a modified thinset?
High bond strength, all-purpose, polymer-modified mortar adheres to most surfaces. For interior and exterior floors and walls.
What happens if you use modified thinset on Ditra?
Since DITRA is impervious, it does not deprive the mortar of its moisture. This allows the cement to properly hydrate, resulting in a strong, dense bond coat. In general, we don't recommend the use of modified thin-set mortar to set tile over the membranes because these mortars must air dry to cure properly.
What are the different types of thin sets?
There are two types of thin-set mortars, unmodified and modified. Unmodified is a blend of Portland cement, sand, and water retention agents that the installer would mix with water. This type of thin-set mortar is also referred to as dry-set mortar. It is dependent upon moisture for hydration to gain its strength.
How can you tell the difference between modified and unmodified thinset?
Look for this standard on the packaging (e.g., product meets ANSI A118. 1 when mixed with water). Unmodified thin-set mortar may also be referred to as dry-set mortar by the manufacturer. Modified thin-set mortars are similar to unmodified thin-set mortars, but include additional polymers such as latex.
How long does it take modified thinset to cure?
With most kinds of thinset, it's generally advisable to wait at least 48 hours after application before walking on or applying pressure to the tile. Manufacturers often recommend allowing a window of 24 to 48 hours for curing time, and in this case, longer is better.
What thinset is used for porcelain tile?
ANSWER. 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 12x12 or larger should use a 1/4" sq.
How to tell if a thinset is modified?
One easy way to know if what you’re working with is modified or unmodified thinset is to look at the American National Standards Institute or ANSI number on the product. Thinset carries the number A118.1. But, depending on whether the thinset is modified or not, the code will change accordingly.
What is a Sturdi set?
Sturdi Set is Tec’s premium unmodified thinset. It is a great option alongside with Laticrete or Bostik Ditra Set. A lower quality yet still reliable option is Tec’s mid range unmodified Full-Set Plus. But again, it may be a better idea to go for the premium.
What is the name of the compound that makes concrete stronger?
After creating more than 300 different chemical compositions, he finally discovered a liquid latex polymer that, when added to the thinset mix, would make the concrete stronger, durable, and more flexible. That is how “Laticrete,” one of the best-known modified thinsets on the market came to life.
Why does cement harden when mixed with water?
Adding water to Portland cement starts a chemical reaction known as hydration. The cement reacts with the water and forms interlocking crystals, which make cement hard.
Can you grade thinset?
So yes, you can actually “grade” your thinset options by simply looking at the ratio between these three key components.
Is Laticrete 272 premium?
After all, it’s a leading innovator and pioneer in the industry (and, no, no bias here.) Most professional installers consider Laticrete 272 to be the premium option, followed shortly by Laticrete 317. In all honesty, there isn’t that much of a difference between these two products, except if you decide to add admix and turn them into modified thinset.
What is an unmodified thinset?
The unmodified thinset works well with the membrane, using its natural moisture to create interlocking bonds for security and durability. If you’re installing radiant floor heating or a similar type of flooring, unmodified is probably your best bet.
What is thinset made of?
Thinset is usually composed of fine sand, cement, and a chemical agent that retains water. This water-retaining agent is typically an alkyl derivative of cellulose. Plus, thinset may have a polymer or latex additive in the mix to improve its bonding power.
How is thinset determined?
The levels or grades of the different types of thinset are determined by the amount of cement used in the mixture. For example, thinset with a higher ratio of cement to sand is better and more durable. The more sand is present, the less durable the product will be. You’ll need to identify what level of staying and binding power you need for your project, and then select a grade or level of thinset that will offer the bond strength you want.
Can modified mortar be used on tile?
In addition to offering a more durable bond, modified thinset doesn’t shrink as much as unmodified mortar, and therefore it doesn’t lead to as many tile cracks in years down the road.
Can you use thinset on tile?
You might use thinset to install tile flooring in your home, or you may apply it outside if you’re creating an eye-catching tile design along the edge of a pool or as a decorative mosaic. Thinset works well over cement/fiber board as well as actual cement. You can also apply it over waterproofing membranes.
Does modified thinset need air?
Modified thinset requires air in order to cure properly, and it’s important to allow for thorough curing time. Once the material has had enough time to cure, you’ll be rewarded with a long-lasting, solid, durable bond between tile and backer board or concrete.
Who invented modified thinset?
The Rise of Modified Thinset. To help strengthen thinset, Henry Rothberg invented a synthetic form of latex to be added to the thinset, thereby kickstarting the whole segment of modified thinsets. He took inspiration from modified concrete mixes of the 1920s that were used to repair and strengthen sea walls.
How to mix thinset?
Always add the dry thinset mix to the water — not the other way around. Use a drill fitted with a mixing paddle to mix the thinset. Mix the thinset as if you’re mixing batter. Start slowly so as not to splash the powder or water out of the bucket and stop when it’s the consistency of frosting or peanut butter.
How long does it take for modified thinset to dry?
When sandwiched between two impervious layers — the tile and the installation membrane — drying can only take place through the open grout joints, which can take as long as 60 days!
How long does it take for thinset to cure?
This type of system failure will not be covered by most industry warranties. It usually takes 2-28 days for thinset to fully cure but make sure to defer to curing times provided by the manufacturer for the thinset you’re using in your project.
How to test if thinset is still viable?
To test if the thinset is still viable to use, test it with your finger. If the thinset sticks to your finger, it should still stick to the surface being tiled. If not, throw it out and start a new batch. Ensure that there are no air gaps during application of thinset.
Why do people use thinset?
Back in the 1940s, people used 2-3 inches of thinset beneath their tile. That’s because they needed to make sure that the cement had enough moisture to fully cure. If there wasn’t enough moisture, the thinset wouldn’t be strong enough to bond the tile to the subfloor.
Can you use unmodified thinset on radiant floor?
Therefore, it’s best to use unmodified thinset when working with an impervious installation membrane like Prodeso for installing radiant floor heating . 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 ...
