Stage one of the Allnex AQUAGUARD™ Fibretech System involves draining the pool using high out-put pumps. The structural composition of concrete allows the pool to be emptied without requiring any bracing. Dependant on the size of the pool, the draining process is usually complete within 1 to 1.5 hours.
A large industrial tarp tent is then erected over the swimming pool site to assist with protecting the AQUAGUARD™ products and our Technicians from UV rays and weather elements. This tent also assists with containing dust and fibres, ensuring a clean and safe work site.
Our team ensure safety is paramount throughout the entire renovation process, with the use of full Personal Protective Equipment and the latest in specialised trade tools.
Once the pool has been emptied and thoroughly dried, the old and defective plaster and/or paint is removed by our technicians using specialised grinders. The grinding process is a methodical and extensive operation which allows our technicians to diagnose any underlying issues, all while removing the plaster or paint to expose the underlying shell. This process can take between 1-3 hours to complete.
Special attention is paid to concrete swimming pools suffering with delaminating or drummy areas and structural cracks. Treatment for these issues is meticulous and labour intensive, ensuring complete removal and repair.
Delaminating areas can range in size and severity, from the size of a coin to the size of a coffee table or larger. Delaminated areas require complete removal and application of new plaster to reconstruct and prepare the surface for the following layers. Structural cracks fracture both the plaster and concrete layer of the pool shell. This can be caused by two main factors; movement in the pool surrounds and/ or incorrect spacing of reinforcement bars within the concrete shell.
To repair structural cracks, the damaged area is widened and filled with a Vinyl Ester Filler, it is then reinforced with several layers of fibreglass matting. This multi-step process enables flexibility in the structure, thus reducing the likelihood of further cracks in the future. It also significantly enhances the strength and durability of the pool’s interior.
Dependant on whether your pool has a tiled waterline, Perth Pool Co offer each client the option of keeping the original tiles, removing them completely or replacing with new mosaic tiles from our extensive swimming pool tile range.
The second stage of the resurfacing system involves the Diamond Key Cut process. This process of keying in or securing the fibreglass to the concrete is critical and must be done correctly to ensure the new fibreglass layer permanently bonds to the concrete shell.
Once complete a Vinyl Ester Resin Primer is applied to the entire pool interior. This primer adheres to the freshly ground shell preparing the surface for the new fibreglass laminate.
A 300gsm Chopped Strand Fibreglass Matting is applied in conjunction with a secondary layer of Vinyl Ester Resin. These layers consolidate or fuse, which removes any hidden air pockets within the new fibreglass laminate. High traffic areas, such as steps and swim outs, will have this process repeated, providing strength and durability while the laminate and primer yields a superior chemical and water resistance, ensuring long lasting product performance.
The third stage of the resurfacing process consists of ensuring the fibreglass matting layer has fully cured in preparation for the Vinyl Ester Fillcoat. This Fillcoat is applied to the entire pool interior and ensures any small holes or imperfections possibly left after the fibreglass layer are removed. This layer also consists of the first stage of pigment or colour which enhances the final cosmetic finish. It is imperative the Fillcoat is applied correctly, as not only will this create a smooth surface for the final Top Coat but also a secondary chemical barrier. This process is then left to fully cure overnight.
The finishing stage of the AQUAGUARD™ system involves a light grind, ensuring the removal of any final imperfections. At this stage we install a customised Non-Slip Surface to high traffic areas, steps and swim outs. Our Senior Technicians will then conduct a final inspection of the pool interior to ensure the pool is ready for the final Top Coat.
The Top Coat layer is not only vibrant and decorative but also contains built in protectants in the way of Styrene Wax, which prevents colour fading and provides exceptional durability. This coat needs to be applied carefully and according to manufacturer specification.
We undertake stringent quality control procedures and testing throughout the renovation, ensuring the highest level of product performance.
A final and comprehensive inspection of the resurfaced pool will be carried out by a Senior Technician, once the Top Coat process is complete. Once approved, the area will be fully cleaned and all equipment and the tarp tent removed.
The Senior Technician will then provide information on the completed resurface and run through any questions you may have.
Detailed swimming pool pre start instructions are provided to each client to assist with refilling the pool once fully cured.
The result… An amazing looking pool with an exceptionally smooth and durable finish!
