How to Make Mortar Stick Better

I. Mortar’s Importance in Construction


Mortar is a super important component in construction for many reasons. It plays a crucial role in keeping a building strong and steady. Imagine it like glue. It holds bricks, stones, or blocks together to make sure everything stays in place and maintains structural integrity. It also acts as a shield, protecting buildings against extreme weather conditions.


Mortar does another cool thing. It ensures an even distribution of the building’s weight, preventing the formation of gaps that might allow water to enter.


Mortar is a crucial factor in keeping the building strong and tough. Additionally, mortar adds aesthetic appeal and gives the building a nice appearance.








II. The Significance of Strong Mortar Adhesion


Mortar adhesion decides how well things like bricks or stones stick together in a building. It’s important because it keeps everything strong and prevents it from falling apart. Mortar adhesion is a big deal for making sure a building stays together and stays strong.







Why is mortar not sticking?


1. Check the surface issue.

Make sure the surfaces you’re applying mortar on are clean and dry. Remove any dirt or moisture as it jeopardizes sticking.


2. Blend mortar mix properly.

The mortar mix has to be mixed well. Poor mixing can lead to poor adhesion in mortar.


3. Use the correct materials.

Sometimes, when you use the wrong type of mortar or mortar adhesive, it could result in poor adhesion.


4. Applying mortar correctly.

Using too little or too much mortar during application can impact its sticking ability.


5. Consider the weather element.

Extreme weather conditions like heat or cold can impact mortar adhesion as well. Take this into consideration when applying mortar mix.






6. Missing mortar adhesive.

Mortar adhesive or mortar bonding agents are important elements in mortar adhesion. Using mortar adhesiveness can significantly increase mortar adhesiveness.






7. Allow the mortar to be cured naturally.

The curing process is important for mortar to dry and set. Remember not to rush this process as it also leads to poor sticking.


8. Too much or too little water

Achieving ideal mortar adhesion requires maintaining a specific level of moisture. If the mortar is too dry or too wet, it can compromise the bonding strength.






How do you make mortar stick better?


A gentle reminder to use high-quality sand, cement, and additives. As they are the crucial ingredients to determine mortar adhesion. And strictly follow the manufacturer’s guidelines. Use the recommended proportions of sand, cement, and water. HPMC powder is a good recommendation for mortar adhesion!




III. 4 Ways to Improve Mortar Adhesion


Having examined the potential reasons for mortar not sticking and how to improve its adhesion, it is also essential to consider the following points.


1. Properly treat the surface before applying mortar.

Preparation is crucial for ensuring optimal mortar adhesion. Clean the surface thoroughly by removing dust, dirt, grease, and loose particles. If the surface is too smooth, use a wire brush to roughen it, improving mortar adhesion.






2. Use high-quality raw materials and mix thoroughly.

Select the correct type of mortar for your project, as different mortars suit different purposes. Quality raw materials, including sand, cement, and auxiliaries, significantly enhance mortar adhesion. Follow the manufacturer’s guidelines for mixing, using the recommended ratio of sand, cement, and water.


3. Control humidity

Maintain proper humidity during and after construction to prevent the mortar from being too wet or too dry. Cover the mortar with a damp cloth or plastic sheet to avoid rapid drying.


4. Proper application process

Ensure a well-organized workflow during construction. Apply mortar evenly and consistently for good surface coverage. Use tools like a trowel to achieve the desired thickness and texture.








IV. Enhancing mortar adhesion with additives


WOTAIchem manufactures a list of construction chemicals for your construction projects. Each comes with a specific type of function. Here’s the list of the products we provide:


1. Polymer Additives: Rispersible polymer powder, Polyvinyl alcohol powder.

Functions: Improve adhesion, workability, flexibility, reduce cracking, and good water resistance.


2. Mortar accelerator: Calcium formate.

Speeds up the setting time without compromising mortar adhesion and strength.


3. Cellulose ether additives: HPMC, HEMC/MHEC, HEC cellulose.

Functions: Retain enough water content in mortar mix, good workability, increased bonding, reduced sagging.


4. Superplasticizers: Melamine water reducer, polycarboxylate water reducer.

Functions: Improve workability, fluidity, and strength; reduce water consumption.


HPMC cellulose is highly recommended for increased mortar adhesion. Workability and water retention as well. HPMC powder also prevents mortar from quick-drying, providing better adhesion.
