Cemcrete Underwater Pool Patching - Marbelite Repair Compound - 1kg
Product Description
Fix 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 pool repairs quick, easy, and cost-effective. This specialized 1kg patching compound is formulated to work where ordinary cement fails-applied directly to submerged surfaces without disintegrating or washing away.
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, or filling small holes and cracks, 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
Mixing Instructions:
- Use Clean Container - Start with a clean, dry mixing container (plastic or metal)
- Add Water First - Pour small amount of clean water (approximately 150-200ml per 1kg)
- 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
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
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
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
- Cure time: 12-24 hours before re-submerging
Post-Application Care:
- Keep pool pump running to maintain circulation
- Do not vacuum or brush repair area for 3 days
- Avoid swimming directly over repair for 24 hours
- Allow 72 hours before acid washing or chemical treatments
- Monitor repair for first week; reapply if needed for deep damage
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
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
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 patch 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)

Frequently Asked Questions
Q: Can I paint or resurface over the repair?A: Yes, once fully cured (7 days), the patch can be painted, acid washed, or included in full resurfacing.
Q: Will the repair match my pool's colour exactly?A: The marble dust base closely matches most marbelite finishes. Colour may appear slightly lighter initially but will darken with pool chemical exposure over time.
Q: How deep can the repairs be?A: Effective for damage 5mm to 50mm deep. For deeper holes, apply in multiple layers, allowing each layer to cure 30 minutes before adding the next.
Q: Can I use this on fibreglass pools?A: This product is designed specifically for marbelite, plaster, and concrete surfaces. For fibreglass repairs, use fibreglass-specific repair kits.
Q: Does it work in saltwater pools?A: Yes, fully compatible with salt chlorination systems and all pool chemical types.
Q: How long will the repair last?A: When properly applied, repairs are permanent and will last as long as the surrounding pool surface.
