Waterproofing/Resurfacing/Decorative Surfaces – Concrete Swimming Pools Repair.

Specification New Concrete Pools  | VIDEO

Concrete Swimming Pools repair – with very smooth surfaces, Marblesheen, pebblecrete and other decorative surfaces, are prone to extreme variations in surface quality due to raw material variations, application techniques, marblesheen additives and surface deterioration. Inspect the surface carefully for soundness. If the surface is crumbly, soft, or drummy in any area, it is suspect and must be removed and repaired using Maxrest.

Products required


CAUTION: The following preparation details MUST be adhered to for the successful adhesion of MAXSEAL FLEX.


1. Prepare area to be coated by removing any loose materials ensuring a clean and sound surface, free from efflorescence, laitance, organic growth and other contaminants.

2. Apply MAXREST PASSIVE  to exposed steel to protect against corrosion.

3. Any damage to the surface should be repaired using MAXPLUG, where leaking, or MAXREST where there are no leaks

4. Using a “RIPPER” disk with a 24 grit minimum abrade the total surface to create an open porous base.
Use commercial Hydrochloric or Muriatic Acid to etch the surface thoroughly, a small area at a time.
Immediately scrub the entire surface with a NYLON  broom. When the bubbling reaction stops (approximately 5-15 minutes), flush the entire area with fresh water.
NEVER ALLOW THE ACID RESIDUE TO DRY ON THE SURFACE after the surface has been etched correctly, the surface needs to be neutralised with a solution of Bicarbonate and water (1Kg Bicarbonate 10 litres warm water) flush with clean water.
It is important to concentrate on a small, workable, section at a time. This will ensure that no bicarbonate of soda is deposited onto the surface.

5. Thoroughly wet the entire surface before applying the first coat of MAXSEAL FLEX. The MAXSEAL FLEX is a flexible cement-based waterproof coating that will not only prevent moisture from escaping the pool but will also prevent ground water from entering the pool.

6. Leave over night between coats.

7. Dampen surface before applying second coat.

8. When rendering over MAXSEAL FLEX a slurry coat of neat Bondcrete mixed with cement should be “flick” applied to the surface to assist with adhesion.

9. Allow 5-7 days to cure before finishing the surface. Waterproofing Concrete Swimming Pools Repair
