Drying Your Liquid Screed
Drying Times For Screed – A Guide To Avoiding Costly Mistakes
So, you’re on a tight deadline. Every day spent drying your liquid screed is another day before the next stage of the project can begin. It’s tempting to rush the process, maybe crack open a window or two, even walk on it before it’s ready. But trust us, at Buxton Flow Screeds, we’ve seen the consequences of that impatience first-hand – cracked surfaces, uneven finishes, and a costly rework.
After decades of experience, we know that patience is what you need when drying your liquid screed.
This guide provides clear, accurate drying time guidelines to help DIYers, builders, and construction companies achieve a perfect finish and avoid those frustrating (and expensive!) setbacks.
The First 48 Hours – Patience is Key
The initial 24-48 hours after your liquid screed is poured are absolutely critical. Think of it like this – you’ve just laid the foundation for a perfectly smooth, level surface. Now, it needs time to settle and solidify without any disturbances.
Here’s the golden rule: hands off! For the first two days, resist the urge to walk on the screed or allow any traffic across its surface. Even seemingly minor disruptions can create imperfections that will haunt you later.
Creating the Ideal Drying Environment:
During this initial curing period, your main goal is to control the moisture levels. While you don’t want the screed to dry too quickly, you also don’t want it to become overly saturated.
- Seal it up – Keep all windows and doors tightly shut to prevent drafts and rapid evaporation. This helps the screed cure evenly and prevents cracking.
- Block the sun – Direct sunlight can cause uneven drying and surface discolouration. If your project is exposed to sunlight, use temporary covers to shade the screed.
The Ideal Climate for Drying Your Liquid Screed
The ideal for drying liquid screed is a temperature of around 20°C and relative humidity of 65%. Under these conditions, you can generally expect the screed to dry at a rate of 1mm per day for the first 40mm of depth, and 0.5mm per day for any depth beyond that.
But what if it’s not a perfect day?
High temperatures and low humidity – This will speed up the drying process. While that might seem like a good thing, excessively rapid drying can lead to cracking. So, if you’re experiencing a heatwave, you might need to take extra precautions to slow down the drying, such as lightly misting the surface with water.
Low temperatures and high humidity – This will slow down the drying process. In colder months or damp conditions, you might need to consider additional heating or dehumidification to keep things on track.
48 Hours and Beyond – Opening the Doors (and Windows!) to Faster Drying
You’ve made it through the first 48 hours, and your liquid screed is well on its way to becoming a solid foundation. Now it’s time to gently encourage the drying process.
Provide Fresh Air:
After the initial curing period, it’s time to let your screed breathe. Open the windows and doors to allow for good ventilation and air circulation. This helps to remove excess moisture and speed up the drying process.
Why Wait 7 Days Before Force Drying?
While you might be tempted to crank up the heat or bring in a dehumidifier right away, it’s important to resist the urge for at least 7 days. Force drying too early can cause the screed to dry unevenly and lead to cracking or curling.
Introducing the Dehumidifier:
After 7 days, you can introduce a dehumidifier to accelerate the drying process. This is particularly useful in areas with high humidity or limited ventilation. Here are a few tips for using a dehumidifier effectively:
- Choose the right size – Make sure the dehumidifier has enough capacity for the size of the room.
- Keep it closed – Close all windows and doors to create a sealed environment for the dehumidifier to work efficiently.
- Monitor the moisture levels – Regularly check the dehumidifier’s water tank and empty it as needed. You can also use a moisture meter to track the screed’s drying progress.
A Reminder from your Friends at Buxton:
