Step-by-Step Repair Guide: Sealing Water Leaks in Concrete and Masonry
What You’ll Need:
- QUIKRETE® Hydraulic Water-Stop Cement
- Mixing bucket
- Trowel or gloved hand
- Safety goggles & rubber gloves
- Wire brush or chisel
- Clean water
1. Prepare the Surface
Use a chisel and hammer or wire brush to enlarge the crack or hole to a minimum depth and width of ¾ inch. The edges should be square or undercut (not V-shaped), which helps the repair material lock in more securely. Tip: Remove all loose or crumbling material, dirt, and dust from the repair area.
2. Mix the Product
In a clean container, quickly mix small amounts of Water-Stop Cement with cold, clean water to a putty-like consistency.
You’ll have only 2–3 minutes of working time, so only mix what you can apply immediately.
Mix Ratio: Approximately 4 parts powder to 1 part water (always follow package instructions for exact proportions).
3. Apply Immediately
Using a gloved hand or trowel, press the mixture firmly into the crack or hole. Hold it in place for 2–3 minutes, or until it has hardened.
Important: If the area has active water flow, press the material into the leak and hold it tight until it stops.
4. Shape and Smooth
Once the material has set, smooth it to match the surrounding surface using a trowel. Make sure the edges are sealed and flush with the existing concrete.
5. Allow to Cure
Although Water-Stop Cement sets in just a few minutes, allow the repair to fully cure for 24 hours before applying any waterproof coatings or paint.
Helpful Tips:
Work in small batches due to the rapid setting time.
Always wear safety gear—this product is caustic and can irritate skin and eyes.
For ongoing leak problems, consider additional drainage or waterproofing improvements.
