Product Description
Fix extensive pool damage instantly without draining a single drop! The Cemcrete Underwater Pool Patching compound is a professional-grade repair solution that sets and cures completely underwater, making large-scale pool repairs quick, easy, and cost-effective. This specialized 5kg bulk-size patching compound is formulated to work where ordinary cement fails-applied directly to submerged surfaces without disintegrating or washing away.
Why Choose the 5kg Size?
The 5kg container is the professional's choice and ideal for pool owners tackling multiple repairs, larger damaged areas, or maintaining commercial pools. Get significantly better value per kilogram compared to smaller sizes while having enough material to complete substantial repair projects without running short. Perfect for property managers, maintenance contractors, and homeowners with larger pools or extensive surface damage.
Why Choose Cemcrete Underwater Pool Patching?
Traditional pool repairs require draining thousands of litres of water, waiting days for surfaces to dry, and losing valuable swimming time. This revolutionary underwater patching compound eliminates all those hassles. Simply mix, apply underwater, and you're done-no draining, no waiting, no water wastage. Perfect for South African pool owners facing water restrictions and wanting to maximize pool usage year-round.
The formula combines cement with finely ground marble dust, creating a compound that perfectly matches the colour and texture of marbelite and plaster pool surfaces. When cured, the patch becomes rock-hard and permanent, seamlessly blending with your existing pool finish. Whether you're fixing chips from pool toys, repairing impact damage, filling small holes and cracks, or restoring larger damaged sections, this patching compound delivers professional results without professional costs.

How It Works
Cemcrete Underwater Pool Patching uses specialized hydraulic cement technology that reacts and sets in the presence of water rather than requiring it to evaporate. When mixed to the correct putty-like consistency and pressed firmly into damaged areas, the compound displaces water and bonds directly to the pool surface. The marble dust component ensures colour compatibility with marbelite finishes while providing body and workability. As the compound cures over 24 hours, it develops full strength and becomes an integral part of your pool surface-waterproof, chemical-resistant, and permanent.
Detailed Application Instructions
Surface Preparation:
- Clean the Damage Area - Remove loose material, algae, or debris using a wire brush or pool brush
- Create Rough Surface - For better adhesion, roughen smooth damaged areas with a screwdriver or chisel
- Remove Standing Debris - Ensure repair area is free of loose particles before patching
- Plan Your Repairs - With 5kg available, plan multiple repairs in sequence for efficiency
Mixing Instructions:
- Use Clean Container - Start with a clean, dry mixing container (plastic bucket or metal pan)
- Mix in Batches - For 5kg container, mix only what you need per repair (typically 500g-1kg batches)
- Add Water First - Pour small amount of clean water (approximately 150-200ml per 1kg compound)
- Add Powder Gradually - Slowly add patching compound while stirring continuously
- Mix to Putty Consistency - Achieve firm, play-dough-like texture that holds shape but remains workable
- Work Quickly - You have 5-8 minutes working time before compound begins to set
- Mix Fresh Batches - Don't try to rehydrate or remix compound once it begins setting
Application Method 1 - Trowel Technique (Best for Accessible Areas):
- Scoop mixed compound onto a small rounded trowel (golf ball to tennis ball size)
- Cup your free hand around the trowel to protect compound from water currents
- Submerge and position trowel directly over damage area
- Press compound firmly into hole or crack using trowel edge
- Smooth surface with minimal passes (excess working weakens bond)
- Remove excess material carefully
- Do not disturb repair for 24 hours minimum
- Repeat process for multiple repairs using fresh batches
Application Method 2 - Plastic Bag Technique (Best for Deep/Awkward Areas):
- Place mixed compound in your hand
- Insert hand into plastic bag (sandwich bag or similar)
- Grip compound through bag and invert bag to seal compound inside
- Submerge to repair area while compound remains protected in bag
- Press compound firmly into damage using bag as barrier
- Work compound into all crevices and corners
- Carefully remove bag once compound is positioned
- Do not disturb repair for 24 hours minimum
Large Area Application (Unique to 5kg Size):
- For areas larger than tennis ball size, apply in sections
- Mix larger batches (1-2kg at a time) for efficiency
- Work with a helper for extensive repairs-one mixes while other applies
- Apply thin layers (15-20mm) rather than thick single applications
- Allow 30 minutes between layers for deep repairs
- Feather edges to blend with surrounding surface
Dry Surface Application:
- For above-water repairs, apply directly with trowel
- Keep surface damp during application for better adhesion
- Smooth finish with damp trowel or float
- For large dry areas, work in sections to maintain workability
- Cure time: 12-24 hours before re-submerging
Post-Application Care:
- Keep pool pump running to maintain circulation
- Do not vacuum or brush repair areas for 3 days
- Avoid swimming directly over repairs for 24 hours
- Allow 72 hours before acid washing or chemical treatments
- Monitor repairs for first week; reapply if needed for very deep damage
- Reseal 5kg container immediately after use to preserve remaining compound
Professional Tips for Best Results
Mixing Success:
- Add powder to water (never water to powder) to prevent lumping
- Mix to consistency of peanut butter or firm clay
- Too wet = compound washes away; too dry = won't bond properly
- Mix only what you can apply in 5 minutes
- Use drill with paddle mixer for consistent larger batches (optional)
- Keep mixing tools clean between batches
Application Excellence:
- Work during calm water conditions (turn off waterfalls/jets)
- Apply in morning when pool temperature is cooler for longer working time
- Press compound firmly-good pressure equals strong bond
- For deep holes, apply in layers rather than one thick application
- Slightly overfill holes; compound shrinks slightly as it cures
- Plan repair sequence: start with deepest/largest damage first
- With 5kg, you can afford to be generous-better too much than too little
Large Project Management:
- Break extensive repairs into manageable sections (complete 3-5 repairs per session)
- Keep detailed notes on which areas have been repaired and when
- Take before/after photos for documentation
- Consider working with a partner for large projects
- Schedule repairs during low-use periods for commercial pools
Common Mistakes to Avoid:
- Don't mix too much at once (compound sets quickly)
- Don't work the patch excessively after placement (weakens bond)
- Don't swim or vacuum near patches for 24 hours minimum
- Don't expect perfect colour match on first day (lightens as it cures)
- Don't apply in very cold water below 10 C (slows setting time)
- Don't leave container open between uses (moisture degrades unused compound)
