Mortar Additives for Cold Weather-Calcium Formate

Calcium formate is a mortar accelerator for cold weather. It speeds up the setting and curing time of mortar in cold temperatures.


WOTAIchem calcium formate is also an antifreeze additive for mortar. It helps maximize initial strength during cold weather. Adding calcium formate to your mortar mixture is your go-to choice. It can prevent issues like mortar drying too quickly.


Mortar Additives for Cold Weather-Antifoaming Agents

Defoamer is an essential additive for cement in cold weather construction applications.


Our antifoaming agent is also known as polyether defoamer. It can eliminate air bubbles within the mortar mix. Improving the mortar workability and resistance to freeze-thaw cycles. This helps prevent cracking and damage caused by freezing and thawing in cold weather. Improving your mortar surface performance.



Mortar Additives for Cold Weather-Superplasticizers

Water reducing agents is one of the must-have mortar cold weather additives. We provide two types of water reducers for your construction. They are SM and PCE superplasticizers. These water reducers can reduce the water content of the mortar mix and maintain its strength.


Also, the mortar plasticizers improve mortar flowability. Helping you get a better application experience.

Have any questions? We’re here to help you out.

Can you use mortar in cold weather?

Yes! You can use mortar in cold weather. But certain precautions need to be taken to ensure proper performance. In cold weather, mortar may experience slower setting times and reduced workability. This can affect construction timelines and quality. To address these challenges, it’s advisable to use cold weather mortar additives.


Plus, the proper curing methods are also important. For example, covering laid mortar with insulating blankets. This method can also help prevent freezing and ensure optimal strength development.

What is the minimum temperature for laying mortar?

The minimum temperature for laying mortar is above 40°F (4°C). Below 4℃ can be categorized as mortar freezing temperatures. There is a risk of mortar freezing. It’s important to avoid laying mortar in freezing temperatures. You can also contact our expert for proper curing tips for your finished product.

What is the mortar setting time?

The setting time of cold weather mortar varies in low-temperature conditions. Mortar sets at a slower rate in colder temperatures. The average temperature ranges from 1.5 to 3 hours. However, other factors can also affect curing time. For example, mortar mix design, ambient temperature, and humidity levels can affect setting times.
