Mixing floor leveller correctly is crucial for a smooth, even surface. Here's a step-by-step guide:
-
Prepare Your Materials: Gather your floor leveller powder, clean water (follow the manufacturer's specified amount), a mixing bucket, a mixing paddle (ideally a drill-mounted paddle), and safety glasses.
-
Add Initial Water: Pour approximately 2/3 of the total required water into the clean mixing bucket.
-
Add the Powder: Gradually add the floor leveller powder to the water while stirring. This helps prevent clumping.
-
Begin Mixing: Start mixing the powder and water with your mixing paddle. Ensure the paddle reaches the bottom and sides of the bucket.
-
Add Remaining Water: Once the mixture starts to combine, add the remaining water.
-
Continue Mixing Thoroughly: Continue mixing for the amount of time specified by the manufacturer. Aim for a smooth, lump-free consistency, similar to a thin batter. The mixture should flow easily. Overmixing can introduce air bubbles, which can weaken the leveller. Undermixing can lead to an uneven consistency and poor performance.
-
Check Consistency: Before pouring, double-check the consistency. It should be pourable and self-levelling, as indicated on the product packaging.
Important Considerations:
- Follow Manufacturer's Instructions: Always refer to the specific instructions provided by the floor leveller manufacturer. Water ratios, mixing times, and application methods can vary.
- Use Clean Equipment: Ensure your bucket and mixing paddle are clean to avoid contaminating the mixture.
- Work Quickly: Floor leveller has a limited working time. Prepare and apply it promptly.
- Safety First: Wear safety glasses to protect your eyes from splashing. Consider wearing a dust mask when handling the dry powder.
- Environmental Conditions: Temperature and humidity can affect the setting time of the leveller. Follow the manufacturer's recommendations for optimal conditions.
Example:
Let's say your floor leveller requires 5 liters of water per 25 kg bag.
- Pour approximately 3.3 liters (2/3 of 5 liters) of water into the bucket.
- Gradually add the 25 kg bag of floor leveller powder while stirring.
- Mix thoroughly.
- Add the remaining 1.7 liters of water.
- Continue mixing until smooth and lump-free, following the manufacturer's recommended mixing time.
By following these steps and carefully reading the manufacturer's instructions, you can effectively mix floor leveller for a professional and long-lasting result.
