Maxisil Pool & Fountains Sealant
Silicone sealant for pools, spas and fountains
Maxisil P Pool & Fountains Sealant is a neutral-cure silicone formulated for specified joints in swimming pools, spas, fountains and similar water features. Choose this pool-specific formulation when the finished joint will be exposed to pool or fountain service conditions. Suitable for service after curing does not mean it can be applied underwater.
Where it fits
- Compatible pool and spa joint details that call for a flexible, water-exposed silicone sealant.
- Fountain and water-feature joints within the manufacturer's substrate and chemical-exposure limits.
- Selected expansion, perimeter and connection joints where proper joint geometry and preparation are provided.
- Not for drinking-water applications. Use a product specifically approved for potable-water service when that is required.
Choose the pool formula and color
Choose from the Pool & Fountains color variants above; each is a 310 mL cartridge. This is not an all-purpose substitute for Wet Area silicone or Natural Stone silicone. Do not use Maxisil P on marble or natural-stone swimming pools: the current manufacturer Pool sheet excludes those substrates and refers to Natural Stone silicone for stone applications. Specialized pool finishes also require compatibility review.
Installation and the pool-fill waiting period
- Apply to properly prepared joints: clean, dry, sound substrates according to the manufacturer sheet; do not apply into a filled pool.
- Application temperature: approximately 5–35°C (41–95°F).
- Curing rate: approximately 2–3 mm per 24 hours at 23°C and 50% relative humidity. Full cure varies with joint depth and conditions.
- Before filling: the manufacturer states a minimum of four days, preferably two weeks before filling. Deeper joints or unfavorable conditions may require additional curing; follow the current technical sheet and project specification.
For tooling, use the Maxisil Applicator and Smoothtex A. See the current Maxisil Pool technical data sheet for joint and substrate requirements.
Common questions
Can I use this to patch a leaking joint while the pool is full?
No. Pool-service suitability is not permission to install the product underwater. Drain and prepare the joint as specified.
When can I refill the pool?
Allow at least four days; the manufacturer's preferred period is two weeks. Confirm full cure for the actual joint depth and site conditions.
Do you have a contractor case?
Yes. The Pool & Fountains case contains 15 cartridges of one chosen color plus a gun.
