Care Instructions for Your Fibreglass Pool
Updated: 12 minutes ago
Your pool has been resurfaced using the Aquaguard® Fibretech Pool Resurfacing System.
Correct pool care and water chemistry are essential to maintaining the appearance, performance and service life of the new surface. Failure to properly maintain the pool water may result in staining, discolouration, fading, surface deterioration or other damage and may affect warranty coverage.
These instructions should be read together with the pool chemical manufacturer's instructions and any documentation provided by Splash Pool & Spa Resurfacing.
1. Initial Filling of the Pool
The resurfaced pool must remain empty and dry for a minimum of 7 days following completion of the resurfacing works.
Longer curing periods may be required in cooler weather or where otherwise advised by Splash Pool & Spa Resurfacing.
The pool must not be exposed to moisture during the curing period.
Once the minimum curing period has passed and the surface has been confirmed as fully cured, the pool may be filled with water.
The Allnex Aquaguard® Fibretech Application Guide specifies a minimum 7-day cure before filling and notes that longer curing times may be required in cooler conditions.
2. Water Chemistry After Filling
There is no requirement to wait an additional seven days after filling the pool before commencing normal water balancing.
Water chemistry should be tested and adjusted as soon as reasonably practicable after filling, in accordance with the instructions provided by the relevant chemical supplier.
Chemicals must always be used in accordance with the manufacturer's instructions.
Where appropriate, pre-dissolving chemicals in a clean bucket of pool water before adding them near a return inlet may assist with even distribution.
Do not add concentrated chemicals directly onto the pool surface unless specifically instructed by the chemical manufacturer.
3. Saltwater Pools
Salt may be added as part of the initial water-balancing process.
Where a saltwater chlorination system is used, we recommend using a good-quality, fine-grade pool salt, as this generally dissolves more quickly.
After adding salt:
Ensure the salt is distributed throughout the pool as directed by the salt/chlorinator manufacturer.
Brush or broom the pool surface to assist in dissolving and distributing any undissolved salt.
Do not allow piles or concentrated areas of undissolved salt to remain on the pool surface.
Operate the filtration system in accordance with the equipment manufacturer's instructions.
Allowing concentrated salt to remain in contact with the surface may increase the risk of surface discolouration.
4. Ongoing Water Chemistry
Maintaining stable and appropriate water chemistry is the customer's responsibility.
Pool water should be regularly tested and maintained in accordance with:
the chemical manufacturer's instructions;
the requirements of the pool equipment manufacturer;
the recommendations of the relevant pool professional; and
any specific instructions provided by Splash Pool & Spa Resurfacing.
Avoid prolonged periods of excessively high or low chemical levels.
Particular care should be taken following heavy rainfall, significant water replacement, periods of heavy pool use, equipment failure or extended periods when the pool has not been operating normally.
Do not deliberately maintain chemical levels above the manufacturer's recommended range.
5. Chemical Addition
Always follow the dosage, dilution, application and safety instructions provided by the chemical manufacturer.
Do not mix different pool chemicals together.
Where dilution is recommended, dissolve the chemical as directed before adding it to the pool.
Allow chemicals to disperse through the circulation system before adding further chemicals, unless the chemical manufacturer's instructions state otherwise.
Never leave concentrated chemicals sitting directly on the pool surface.
The Aquaguard® Fibretech system is designed to provide resistance to pool chemicals; however, the manufacturer also notes that pool surfaces can deteriorate over time and that proper procedures and maintenance are important for satisfactory performance.
6. Cleaning & Brushing
Regularly brush the pool walls, floor, steps and other areas to prevent the accumulation of dirt, minerals, algae or undissolved chemicals.
Use pool-cleaning equipment suitable for the surface.
Avoid aggressive scraping, abrasive cleaning methods or equipment that may damage the coating.
Any chemical deposits, staining or discolouration should be investigated promptly rather than being allowed to remain on the surface for extended periods.
7. Water Testing & Maintenance Records – Warranty Requirement
To support any warranty claim, the customer must maintain reasonable records demonstrating that the pool has been properly maintained throughout the warranty period.
As a minimum, we recommend:
Monthly Professional Water Testing
A water test performed by a reputable pool shop or qualified pool professional at least once per month is recommended.
The customer should retain the test result/report or other written record showing the date of testing and the relevant water-chemistry results.
A monthly pool-shop water test is considered acceptable supporting evidence of regular water-chemistry monitoring; however, a monthly test alone does not replace the customer's responsibility to monitor and maintain the pool between professional tests.
Between Professional Tests
Customers should also regularly monitor the pool water and maintain appropriate chemical levels in accordance with the chemical manufacturer's instructions.
Where possible, retain records of:
date of testing;
relevant water-chemistry readings;
chemicals added;
significant chemical adjustments;
salt additions;
unusual water conditions;
major water replacement;
equipment or chlorination issues; and
professional pool-shop testing.
Photographs of test results, digital records or pool-shop receipts/reports may be retained as supporting evidence.
8. How Missed Maintenance May Affect Warranty
A single missed water test or isolated maintenance event will not automatically invalidate a warranty.
However, warranty coverage may be affected where there is evidence of repeated, prolonged or significant failure to properly maintain the pool water or surface, particularly where the condition complained of may reasonably be associated with inadequate water chemistry or poor maintenance.
For warranty assessment purposes, Splash Pool & Spa Resurfacing may request maintenance and water-chemistry records for the relevant period.
Where there is 30 consecutive days or more without reasonable evidence of required water-chemistry monitoring or maintenance, or where records demonstrate prolonged exposure to unsuitable water chemistry, this may be considered a significant maintenance deficiency when assessing a warranty claim.
This does not mean that a warranty is automatically cancelled after 30 days. Any warranty assessment will consider the nature of the alleged defect, the available maintenance records, water-chemistry history, the condition of the surface and any other relevant circumstances.
Where a surface issue is found to have resulted from improper chemical balance, chemical misuse, prolonged neglect, staining, contamination, equipment failure or other customer-controlled maintenance conditions, such damage may not be covered by the applicable warranty.
9. Customer Responsibility for Water Chemistry
The customer is responsible for maintaining the pool water after completion of the resurfacing works.
Splash Pool & Spa Resurfacing does not control:
the source or quality of the pool water;
chemical products selected by the customer;
chemical quantities added by the customer;
operation of the filtration or chlorination system;
frequency of cleaning;
periods when the pool is unattended;
weather exposure;
contamination from surrounding areas; or
subsequent alterations or additions to the pool water or equipment.
Accordingly, warranty assessment may require evidence that the pool has been maintained appropriately throughout the relevant period.
10. Changes, Additives & Unapproved Products
Do not add, mix or apply products to the resurfaced surface other than products intended for use in swimming pools and used in accordance with their manufacturer's instructions.
Do not apply coatings, sealers, solvents, acids or other products directly to the resurfaced surface unless specifically approved by Splash Pool & Spa Resurfacing.
The Allnex Application Guide states that adding or combining other materials or contaminants with Aquaguard® products can affect surface properties and performance, and that adding anything to the topcoat may void the manufacturer's warranty.
11. Water Level & Equipment
Maintain the pool at an appropriate operating water level.
Do not allow the pool to remain empty for extended periods unless specifically advised by Splash Pool & Spa Resurfacing or a qualified pool professional.
Ensure the filtration, circulation and chlorination systems are operated and maintained correctly.
Any equipment failure that may affect water circulation or water chemistry should be addressed promptly.
12. Warranty Claims
If you notice unusual discolouration, blistering, surface deterioration, staining, loss of gloss or any other potential surface issue, contact Splash Pool & Spa Resurfacing promptly.
Do not attempt to sand, chemically treat, repaint, coat or otherwise repair the affected area before contacting us, unless specifically instructed to do so.
For warranty assessment, we may request:
photographs and videos of the affected area;
water-chemistry records;
pool-shop test reports;
chemical purchase or treatment records;
details of chemicals used;
salt/chlorinator information;
maintenance history;
information regarding any equipment failures; and
access to inspect the pool.
Failure to provide reasonable maintenance information may make it difficult to determine whether an issue is related to the resurfacing system, water chemistry, maintenance, equipment or another cause.
13. Important Warranty Note
The resurfacing warranty applies subject to the applicable warranty terms and conditions provided by Splash Pool & Spa Resurfacing.
The warranty does not replace the customer's responsibility to properly maintain the pool.
The Aquaguard® Fibretech Application Guide itself notes that the quality and performance of the finished system depend on factors including surface preparation, environmental conditions and application methods, and recommends following the relevant Technical Data Sheets (TDS) and Safety Data Sheets (SDS).
These Pool Care Instructions form part of the maintenance information provided to the customer and should be retained for future reference.
Please retain all water-testing and maintenance records for the duration of the applicable warranty period.
💧 Water Chemistry Guidelines (Fibreglass Pools)
Maintaining correct water chemistry is vital to protect your pool’s surface and equipment.
Chlorine: 1.0 – 2.0 ppm (never exceed 4.0 ppm). Higher levels will damage the gelcoat surface.
pH: 7.2 – 7.8 (ideal for fibreglass: 7.2 – 7.4, balancing gelcoat longevity with swimmer comfort).
Total Alkalinity: 80 – 120 ppm (can be up to 300 ppm, but ideally 80 – 100 ppm for stability).
Calcium Hardness: 90 – 300 ppm (soft water is corrosive; hard water causes scaling).
Cyanuric Acid (Stabiliser): 30 – 50 ppm recommended (per local pool shop guidance).
Total Dissolved Solids (TDS): < 1,500 ppm. Check annually with a pool professional.
📌 Why this matters:
Low pH = corrosive water that can damage gelcoat and equipment.
High pH = chlorine becomes less effective (at 7.8 pH, chlorine effectiveness drops by half).
Poor balance can cause chalking, staining, or surface blistering.
Tip: Use the Langelier Saturation Index (LSI) to confirm water balance. Keep LSI between -0.5 and +0.5 (slightly positive is safer than negative).
🧽 Maintenance Best Practices
Brush and clean the pool weekly (twice weekly for the first month).
Test water chemistry weekly with a reliable kit.
Run the filtration system daily (minimum 8 hours).
Use a robotic or automatic cleaner where possible.
Keep water level above the skimmer.
Avoid superchlorination/shocking the pool — this can bleach or damage the gelcoat.
Schedule professional servicing at least once per year.
🌟 Important Notes
Always add chemicals gradually and pre-dilute when possible.
Collect water samples from about 45 cm (18 inches) below the surface, ideally near a return jet.
Do not leave the pool drained or partially drained for long periods.
Maintain a logbook of chemical treatments (date, product, dosage).
Non-compliance with water chemistry may void your warranty.
It’s vital for saltwater system swimming pools to use high-quality products that dissolve completely upon contact with water. If a product does not dissolve immediately, it’s important to use a pool brush or broom to distribute it, so that the undissolved material does not sit in one place on the pool surface. This helps to prevent stains or discolouration.
Using low-quality products, or failing to ensure proper dissolution, can lead to permanent stains on pool surfaces — damage that is usually not covered by warranty. Even products labelled for pool use can contain impurities or coarse particles that settle and react, especially if the salt used is of poor purity. In saltwater pools, metals or minerals introduced by impure salt can combine with chlorine or with pool surfaces to produce visible stains.
To avoid problems:
Always choose chemical and salt products specifically graded for pool / saltwater systems.
Pre-dissolve or distribute carefully, especially in areas where water circulation is weaker (steps, shallow ends).
Run circulation and filtration soon after adding chemicals to ensure even mixing.
Brush or sweep the pool surface if you notice undissolved product settling.
Maintain correct water chemistry (pH, chlorine levels, total alkalinity), which helps prevent discolouration and metal precipitation.
Dissolve first in a bucket if needed
Add slowly while pump/circulation is running
Brush / sweep undissolved granules
Test water after treatment
