Information
Application Details
Consumption Joint Design:
The joint width must be designed to be within the movement capability of the
sealant. Movement joint widths with Sikasil Pool shall be > 10 mm and < 15 mm.
Sikasil Pool shall not be used in joints of more than 15 mm width and a minimum
depth or thickness of 6 mm must be applied.
Joint width 10 mm 15 mm
Joint depth 8 mm 10 mm
Joint length / 300 ml ~ 3.5 m ~2m
Substrate Quality Clean and dry, homogeneous, free from oils and grease, dust and loose or friable
particles. Cement laitance must be removed.
Substrate Preparation / Stainless, steel, PVC, GRP, Stainless steel
®
Priming Surfaces must be cleaned using a fine abrasive pad followed by Sika Aktivator-
®
205 (Sika Cleaner-205) using a clean towel / cloth. There shall be a ‘flash-off time
of at least 15 min.
Concrete, tiles, glazed tiles:
®
Surfaces must be primed with Sika Primer -3N using a brush. Before sealing the
joint there shall be a ‘flash-off time of at least 30 min. (max. 8 hrs.).
For other substrates please contact the Sika Technical Service Department for
advice.
Important note: Primers are only adhesion promoters. They neither substitute for
the correct cleaning of the surface nor improve their strength significantly.

Application
Instructions
®
Application Method / Sikasil -Pool is supplied ready to use.
Tools
After suitable joint and substrate preparation, insert the Backing Rod to the required
depth and apply primer if necessary. Insert cartridge into sealant gun and firmly
®
extrude Sikasil -Pool into the joint making sure that it is in full contact with the side
®-
of the joint. Fill the joint and avoid air entrapment. Tool Sikasil Pool firmly against
the joint sides to ensure good adhesion.
Use masking tape where sharp and exact joint lines or exceptionally neat edges are
required. Remove the tape whilst the sealant is still soft. Finish the surface of the
joint with a suitable smoothing liquid for a perfect sealant surface.
®
Cleaning of Tools Clean all tools and application equipment with Sika Kwiklean immediately after
use. Remove hardened / cured material mechanically.
Notes on Application / Do not use on bituminous substrates, natural rubber, chloroprene, EPDM or on
Limitations building materials which might bleed oils, plasticizers or solvents.
®
Do not use in totally confined space because Sikasil -Pool requires atmospheric
moisture to cure.
®
Do not use Sikasil -Pool for structural glazing, insulated glazing, food contact
applications, or for medical or pharmaceutical use.
Recommendation for use in swimming pools / warm water whirlpools:
®
Cure Sikasil -Pool fully before the filling of the pool, minimum 4 days up to 14 days
(dependent on the temperature, ambient humidity and the thickness of the sealant
applied).
For a minimum of fungus attack, disinfect the swimming pool water with chlorine.
The pool water shall be in following conditions:
Swimming pools: 0.3 - 0.6 mg/litre of free chlorine
Warm water whirlpools: 0.7 - 1.0 mg/litre of free chlorine
The present state of the art allows an amount of up to 1.2 mg/litre of free chlorine.
The pH value of pool water has to be regulated to 7.0. Deviations up and down
between 6.5 and 7.6 are allowed in incoming fresh-water.
If there is a very strong smell of chlorine, check the p-H value accordingly.
Regular water circulation is required and must not be interrupted. If interrupted,
partial or variable chlorine concentrations arise and may locally fall below the
minimum concentration.
Do not use acid based detergents as they increase the danger of fungal attack.
In case of a fungal attack, the sealant must be removed completely when joints are
reconstructed.
The required vulcanisation or curing time extends with the increasing thickness of
the sealant applied.
One component silicones must not be used for bonding applications where the
silicone is spread all over the surface. Such applications require a different type of
sealant formulation – please contact Sika Technical Service Department for advice.
