Mortar is a significant element in the construction world when it comes to binding materials together. Even though mortar is versatile, have you ever wondered if it is usable on wood surfaces. Does mortar stick to wood?
Well, that’s a big question among many people. Wood is different in its composition and behavior compared to other surface materials. So it is reasonable to raise this question. If you need more clarification about it, you need to stick around until the end to learn everything you need to know about this matter.
This article will discuss all about mortar, thin set and wood floors. Let us get the ball rolling into the details.
Does Mortar Stick to Wood?
Yes, it does. But only under specific conditions. Mortar has to be mixed with a flexible thin set that’s mixed with latex additives. If the particular conditions are not met, the mortar will not be an excellent binding agent to stick to wood.
If you have chosen mortar to fit tiles/ bricks over a wooden surface or fit wooden tiles over a brick surface, here’s how you should play the game,
- Prepare the mortar by adding a flexible thin-set along with latex additives
- Put on the customized mortar on the backer board.
- Line the bricks over
Yes, it is pretty straightforward. Never apply mortar alone without any other mixture when dealing with a wooden subfloor. Why?
Because the mortar is a binding agent meant for super hard surface materials like concrete.
Wood isn’t a hard surface material. It is actually soft and fragile. The climatic conditions can cause expansions and contractions in wooden surfaces. Suppose you directly put on the mortar on such a vulnerable surface. In that case, it will cause cracks and other similar issues over time.
So you must provide the wooden subfloor with the flexibility it needs. And this is precisely why we incorporate latex additives and thin set into the mixture.
But to your question, does mortar stick to wood? Yes, it does stick to wood when used in the correct proportion.

Does Mortar Damage Wood?
Yes, it will. As we already explained, mortar is a super hardening binding agent used on hard surfaces like concrete. Compare concrete to wood. Two totally different materials, right? Exactly.
Hence mortar is not meant for wood. So it can have adverse effects on wood when applied. Wood is a soft material and prone to expansion and contractions. Temperature and humidity can hugely influence the behavior of wood. They will expand and contract depending on the climatic conditions.
Mortar has water as an active constituent in it. And water will cause swelling and deterioration in the woods.
And how is that any good? Exactly. So using mortar on wood isn’t a wise idea.
But what if you incorporate latex additives and a thin set with mortar and use it on wood? In that case, you will immensely suppress the harmful effects mortar can have on wood. Does that mean it is 100% safe? Not at all.
The urethane-based adhesive makes an excellent option for wood materials. Unlike mortar, it is waterproof and does not need water as an active ingredient for curing. It is also flexible and versatile.
Urethane-based adhesive will work great on wood subfloors. Why bother and stick to a risky option like mortar when such an option exists? Exactly.
Does Thin Set Stick to Wood?
Yes, the thin set can stick to a wood floor. But it is no better than mortar. What is a thin set? It is basically a modified mortar tailor-made to stick to tiles. So obviously is also a super hardening binding agent with active water content.
So it is similar to mortar. The only difference is the modification in it. If you choose a thin set to stick to wood, you should choose one with high latex content.
If you do not have a high latex incorporated thin set, manually add latex additives in the proper ratio and use it on the wooden subfloor. Flexibility is critical in the binding agent for woods to not stir up chaos. So if you are using a thin set, make sure it is rich in flexibility.
Again to your question, does thin set stick to wood – yes, it does when used with a high latex content.
Does Thin Set Damage Wood?
You would have already guessed the answer. Yes. It can damage the wood when not applied in proper proportions.
Thin set alone has active water as an essential ingredient in it. If you use it alone, the wood will swell, expand and deteriorate due to the impermeability of the water particles in the thin set.
When wood gets swollen, it can cause cracks and other issues on the floor.
What if You Apply Thin Set that is Rich in Latex Content?
In that case, there will be no threat to the wood as it has enough space to do its thing – expand and contract as it wants without causing a mess.
However, remember there is still high water content in thin set. Over time it can have its effects on the wood.
So it would be best to opt for a urethane-based adhesive which will make a safe and sound option with no potential risks.
Conclusion
The mortar and thin set does stick to wood. But they are not intended to be used on wood. They are suitable to use on hard floors such as concrete. Wood is a soft floor in contrary.
Hence you cannot use thin set and mortar the same way you use it on other hard floors. Stick to the above-explained methods and follow the right proportions to make the right mix of thin-set and mortar to stick to wood.
When done correctly, the negative issues are immensely suppressed and can be stuck to wood safely. However, switching to urethane-based adhesives to stick wood is best as it can serve as a great option, especially for wood subfloors.
