Acrylic resin, water based

12 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 packaging.

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

63.5 %

50.9 %

Resistant to acidic and alkaline detergents, disinfectants and chlorinated water in swimming pools with controlled water treatment equipment.

Not suitable for use if water treatment is by ozone or electrolysis.

Not resistant to organic solvents.

In case of higher chlorine concentrations, the coating may be susceptible to chalking and discoloration. Refer to DIN 19643-2 Treatment of water of swimming pools and baths - Part 2: Combinations of process with fixed bed filters and precoat filters.

120 µm wet film thickness per layer

Beware of condensation. The substrate and uncured applied product must be at least +3 °C above dew point to reduce the risk of condensation or blooming on the surface of the applied product. Low temperatures and high humidity conditions increase the probability of blooming.

No rising moisture (ASTM D4263, polyethylene sheet)

Note: Times are approximate and will be affected by changing ambient conditions, particularly temperature and relative humidity.

Before filling the pool, leave Sikagard®-140 Pool to cure for at least 14 days after the final application. The temperature must not be below +10 °C during the curing process.

Note: Times are approximate and will be affected by changing ambient conditions, particularly temperature and relative humidity.

160 g/m² per layer, minimum 2 layers to be applied

IMPORTANT

Strictly Follow Installation Procedures

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

APPLICATION EQUIPMENT

• Brush

• Fleece roller

• Airless spray equipment

For airless spray application use the following settings:

Existing coatings must be tested to confirm their adhesion to the substrate and their compatibility. As guidance, adhesion test average ≥ 0.8 N/mm² with no single value below 0.5 N/mm².

IMPORTANT

Exposing Blow Holes and Voids

When mechanically preparing the surface, make sure to fully expose blow holes and voids.

EXPOSED CONCRETE OR CEMENTITIOUS RENDER

1. Remove weak cementitious substrates.
2. Prepare cementitious substrates mechanically using abrasive blast cleaning or planing / scarifying equipment to remove cement laitance.
3. Before applying thin layer resins, remove high spots by grinding.
4. Use industrial vacuuming equipment to remove all dust, loose and friable material from the application surface before applying the Product.
5. Use Sikagard®-720 EpoCem® or Sikafloor®-81 EpoCem® to level the surface or fill cracks, blow holes and voids.

Contact Sika® Technical Services for additional information on products for levelling and repairing defects.

COATED SUBSTRATE WITH INADEQUATE ADHESION

1. Remove existing coatings using suitable removal equipment such as abrasive blast cleaning or high pressure water jetting.
2. Prepare cementitious substrates mechanically using abrasive blast cleaning or planing / scarifying equipment to remove cement laitance.
3. Before applying thin layer resins, remove high spots by grinding.
4. Use industrial vacuuming equipment to remove all dust, loose and friable material from the application surface before applying the Product.
5. Use Sikagard®-720 EpoCem® or Sikafloor®-81 EpoCem® to level the surface or fill cracks, blow holes and voids.

COATED SUBSTRATE WITH ADEQUATE ADHESION

1. Thoroughly clean the surface of all contaminants using pressured water cleaning equipment.
2. Lightly abrade or grind the surface with mechanical grinding or abrading equipment to achieve a sheen free surface.
3. Use industrial vacuuming equipment to remove all dust, loose and friable material from the application surface before applying the Product.

IMPORTANT

Ventilation In Confined Spaces

Always ensure good ventilation when applying the Product in a confined space.

Exposure To Direct Sunlight

Note: When the product is exposed to direct sunlight, there may be some discolouration and colour variation. This has no influence on the function and performance of the coating.

SPRAY APPLICATION

1. Spray apply the Product in a continuous operation and at a speed to achieve a consistent thickness and surface finish.

2. Control the layer thickness during application using a thickness gauge. The coating must be continuous, pore free and to the required surface finish.

3. Protect the Product from rain, condensation and water for at least 24 hours at +20 °C and at least 48 hours at +10 °C.
4. Apply additional coats as required.

MANUAL APPLICATION

1. Apply the Product evenly over the surface with a short pile fleece roller at the required consumption.
2. Control the layer thickness during application using a thickness gauge.

3. To achieve a smooth finish, smooth the surface with a brush. The coating must be continuous, pore free and to the required surface finish.

4. Protect Product from rain, condensation and water for at least 24 hours at +20 °C and at least 48 hours at +10 °C.
5. Apply additional coats as required.

Clean all tools and application equipment with water immediately after use. Hardened material can only be removed mechanically.
