Neutral curing silicone

15 months from date of production

The Product must be stored in original, unopened and undamaged sealed packaging in dry conditions at temperatures between +5 °C and +25 °C. Always refer to the packaging.

Refer to the current Safety Data Sheet for information on safe handling and storage.

Compatible with the following non-porous substrates:

• Aluminium

• Anodised aluminium

• Stainless steel

• Copper

• Brass

• Titanium- zinc

• PVC

• Galvanised steel

• Powder and PVDF coated metals

• Glazed tiles

• Glass

Compatible with the following porous substrates:

• Concrete

• Unglazed tiles

For other substrate types, contact Sika Technical Services.

• Good resistance to chlorinated water and common swimming pool cleaning chemicals

The resistance of sealant to chlorine is dependent on the water pH value and the amount of free chlorine.

Contact Sika Technical Services for additional information.

-40 °C min. / +80 °C max

The joint dimensions must be designed to suit the movement capability of the sealant. The joint width must be a minimum of 10 mm and a maximum of 35 mm.

The joint depth must be a minimum of 6 mm and a maximum of 10 mm. For larger joints, contact Sika Technical Services for additional information.

Use closed cell, polyethylene foam backing rod.

+5 °C min. / +40 °C max.

The substrate temperature must be at least +3 °C above dew point to reduce the risk of condensation decreasing adhesion.

+5 °C min. / +40 °C max. 

Sikasil® Pool adheres without primers or activators.

Poor adhesion due to inadequate surface preparation

Note: Primers are adhesion promoters. Primers cannot replace proper surface preparation and surface cleaning.

1. Do not use primers for improving poorly prepared or poorly cleaned joint surfaces.

IMPORTANT

Degradation of sealant due to substrates leaching oil, plasticisers, or solvents

Bitumen, natural rubber or EPDM rubber can leach oils, plasticisers, or solvents that can degrade the sealant and cause the Product to become tacky.

1. Do not use the Product on building materials which leach oils, plasticisers, or solvents.

The substrate must be sound, clean, dry and free of contaminants such as dirt, oil, grease, cement laitance, sealant residues and poorly bonded coatings which could affect adhesion of the primer and sealant.

The substrate must be of sufficient strength to handle the stress induced by the sealant during movement.

1. Use techniques such as wire brushing, grinding, grit blasting or other suitable mechanical methods to remove all weak substrate material.
2. Repair all damaged joint edges with suitable Sika repair products.
3. Remove dust, loose and friable material from all surfaces before applying the sealant.

Use the following priming or pre-treatment procedures to ensure optimum adhesion and joint durability:

NON-POROUS SUBSTRATES

Aluminium, anodised aluminium, stainless steel, galvanised steel or glazed tiles

1. Lightly roughen the surface with a fine abrasive pad.
2. Clean the surface.
3. Pretreat the surface with Sika® Aktivator-205 applied with a clean cloth.

Other metals, such as copper, brass and titanium-zinc

1. Lightly roughen the surface with a fine abrasive pad.
2. Clean the surface.
3. Pretreat the surface with Sika® Aktivator-205 applied with a clean cloth.
4. Wait until the flash-off time is over.
5. Prime the surface with Sika® Primer-3 N applied with a brush.

PVC substrates

1. Prime the surface with Sika® Primer-215 applied with a brush.

Glass substrates

1. Clean the glass with Isopropanol before application.

POROUS SUBSTRATES

Concrete and unglazed tiles

1. Prime the surface with Sika® Primer-3 N applied with a brush.
2. Wait until the flash-off time is over.

Before applying onto natural stone, contact Sika Technical Services.

IMPORTANT

Poor adhesion due to incorrect priming procedure

Incorrectly defined or uncontrolled priming procedures may lead to a variation in Product performance.

1. Test adhesion on project-specific substrates and agree on procedures with all parties before full project application. For more information contact Sika Technical Services.

IMPORTANT

Strictly follow installation procedures as defined in Method Statements, application manuals and working instructions which must always be adjusted to the actual site conditions.

Incorrect acid and base dosage increases the risk of fungal growth.

1. Use the Product in swimming pools and warm water whirlpools with a pH value between 6.5 and 7.6, and free chlorine < 5 mg/L (5 ppm).
2. Free available chlorine level must not be ≤ 0.3 mg/L in swimming pools and ≤ 0.7 mg/L in warm water whirlpools.
3. Maintain continuous water circulation to avoid chlorine concentrations.
4. Do not use acid-based detergents.
5. When joints must be reconstructed due to fungal growth, remove Sikasil® Pool completely beforehand.

1. Apply masking tape where neat or exact joint lines are required.
2. After the required substrate preparation, insert a backing rod to the required depth.
3. Prime the joint surfaces as recommended in substrate preparation. Note Avoid excessive application of the primer.
4. Fit the nozzle and cut it to the desired bead size.
5. Apply the Product into the joint. Note Avoid air entrapment. Make sure that the Product comes into full contact with the adhesion area of the joint.
6. IMPORTANT Do not use tooling products containing solvents. As soon as possible after application, tool the Product firmly against the joint sides to ensure adequate adhesion and a smooth finish. Use a compatible tooling agent such as Sika® Tooling Agent N to smooth the joint surface.
7. Remove the masking tape within the skin formation time of the Product.

Sikasil® Pool must be cured completely before filling the pool: minimum 7 days (depending on the temperature, humidity and thickness of sealant).

Colour variations

Note: Colour variations may occur due to the exposure in service to chemicals, high temperatures or UV-radiation (especially with white colour shade). This effect is aesthetic and does not adversely influence the technical performance or durability of the product.

Clean all tools and application equipment immediately after use with Sika® Remover-208 or Sika® Cleaner-350H. Once cured, hardened material can only be removed mechanically.
