APPLICATION INSTRUCTIONS
SUBSTRATE PREPARATION
The substrate must be clean, dry, sound and homogeneous, free from oils, grease, dust and loose or friable particles. Sikasil® Pool adheres without primers
and/or activators.
However, for optimum adhesion and critical, high performance applications, such as on multi-story buildings, highly stressed joints, extreme weather exposure or water immersion, the following priming and/or pretreatment procedures shall be followed:
Non-porous substrates
Aluminium, anodised aluminium, stainless steel, glass, galvanised steel, powder coated metals or glazed tiles have to be cleaned and pre-treated using Sika® Aktivator-205, wiped on with a clean towel. Before sealing, allow a flash-off time of > 15 minutes (< 6 hours).
Other metals, such as copper, brass and titanium-zinc, must also be cleaned and pre-treated using Sika® Aktivator-205, wiped on with a clean towel. After the necessary flash-off time, use a brush to apply Sika® Primer-3 N and allow a further flash-off time of > 30 minutes (< 8 hours) before sealing the joints.
PVC has to be cleaned and pre-treated using Sika®
Primer-215 applied with a brush. Before sealing, allow a flash-off time of > 30 minutes (< 8 hours).
Porous substrates
Concrete, aerated concrete and cement based renders, mortars and bricks shall be primed using Sika®
Primer-3 N applied with a brush. Before sealing, allow a flash-off time of > 30 minutes (< 8 hours).

For more detailed advice and instructions please contact the local Sika Technical Services Department.
Note: Primers are adhesion promoters. They are neither a substitute for the correct cleaning of a surface, nor do they improve the strength of the surface
significantly.

APPLICATION METHOD / TOOLS
Sikasil® Pool is supplied ready to use.
After the necessary substrate preparation, insert a suitable backing rod to the required depth and apply any primer if necessary. Insert a foil pack or cartridge into the sealant gun and extrude Sikasil® Pool into the joint making sure that it comes into full contact with the sides of the joint and avoids any air entrapment.
Sikasil® Pool sealant must be firmly tooled against the joint sides to ensure adequate adhesion.
It is recommended to use masking tape where exact joint lines or neat lines are required. Remove the tape within the skin time. Use a compatible tooling agent (e.g. Sika® Tooling Agent N) to smooth the joint surfaces. Do not use tooling products containing solvents.

CLEANING OF EQUIPMENT
Clean all tools and application equipment immediately after use with Sika® Remover-208. Once cured the residual material can only be removed mechanically.


IMPORTANT CONSIDERATIONS
▪ Sikasil® Pool cannot be overpainted.
Colour variations may occur due to exposure to chemicals, high temperatures and/or UV-radiation (especially with the colour shade white). However, a change in colour is purely of aesthetic nature and does not adversely influence the technical performance or durability of the product.
▪ The use of non-prescribed tooling agents must be tested prior to use in application to ensure they will not cause aesthetical changes (such as discolouration).
▪ Do not use Sikasil® Pool on bituminous substrates, natural rubber, EPDM rubber or on any building materials which might bleed oils, plasticizers or solvents that could attack the sealant.
▪ Do not use Sikasil® Pool for structural glazing or insulated glazing, and food contact applications.
▪ Do not use Sikasil® Pool for medical or pharmaceutical uses.
▪ Before using Sikasil® Pool on natural stone, please contact our Technical Service Department for advice.
▪ Recommendations for use in swimming pools / warm water whirlpools: Allow Sikasil® Pool to cure completely before the filling of the pool; minimum of 7 days (depending on the temperature, humidity and thickness of the sealant applied).
▪ The resistance of a sealant to chlorine is dependent on the pH value of the water and the amount of free chlorine.
▪ Sikasil® Pool can be used in swimming pools and warm water whirlpools in which a pH value between 6.5 and 7.6 is maintained, and the free chlorine remains less than 5 mg/l (5 ppm).
▪ To reduce the risk of fungal attack on Sikasil® Pool, the free available chlorine level shall not be ≤ 0.3 mg/l in swimming pools and ≤ 0.7 mg/l in warm water whirlpools. Continuous water circulation is required to avoid chlorine concentrations.
▪ If there is a very strong smell of chlorine, check the pH value accordingly.
▪ Do not use acid-based detergents as they increase the danger of fungal attack.
▪ When joints are reconstructed due to fungal attack, Sikasil® Pool must be removed completely.
