ApplicationCoverage

• Rough cast: 1.5 kg/m_(one 25kg bag of KATYMPER PISCINE for approximately 16 m_) • Plaster : 12 to 14 kg /m_ for a thickness of 8 mm(one 25kg bag of KATYMPER PISCINE for approximately 2 m_).

Quality of substrate The substrate (concrete or waterproof plaster) must be sound, cohesive, clean andfree from dust or any substance that might affect the adhesion of the KATYMPERPISCINE product (laitance, form-removal oils, traces of paint, etc.).

Preparation of substrate Substrates which are uneven or have other surface defects (bubbling,honeycombing, spalling, etc.) must be reshaped or repaired. Use, for example, aSIKACEM PACK – based mortar.Re-entrant corners must be rounded off with a groove made from SIKACEM PACK-based mortar, for example.Rough cast :

• The day before application, wet the substrate to saturation point. Thenremove excess water: substrates must not be sweating.

• Prepare a rough cast made with 6 litres of SIKALATEX solution (4 litres ofwater and 2 litres of SIKALATEX) mixed with a 25kg bag of KATYMPERPISCINE. If applying the rough cast by projection, add approximately 5kgof 0/4 mm sand to the above mixture.

• Apply the rough cast to the substrates: by brush, trowel or projection.• Allow the rough cast to set before applying KATYMPER PISCINE : it must

be hard to the fingernail (waiting time: 12 to 24 hours at 20°C).• Note: on the floor surface, the application of rough cast is optional for

concrete paving which has a push-broom textured finish.

ApplicationConditions for use

• Temperature range for use: + 5 to + 30°C (substrate, product, surroundingair).

• In hot weather conditions it is recommended that work be done once thetemperature starts to fall (later in the day), in order to limit the gasexchanges which might be caused by the heating up of the substrate.

• Avoid working in very hot weather, direct sunlight or dry or heavy winds, toavoid dehydration, scorching or cracking of the coating.

• Be careful of efflorescence due to carbonation of the coating in the eventof application/start of hardening in temperatures lower than 8°C and highrelative humidity.

• If applying during pollination of the surrounding vegetation: protect thecoating during application to prevent it being contaminated by pollen (riskof stains forming).

Preparation of the mixture • Mixing equipment: slow-speed mixer (300 revs/min) equipped with a4-blade propeller, concrete mixer or plaster-projection machine.

• Quantity of water for mixing: 4.5 to 5 litres of water per 25kg bag(depending on the temperature and required consistency).

• Be careful to observe the correct quantity of water for mixing.• Do not mix for too long. Let the mixture stand for approximately 10

minutes.

Cleaning of tools Clean with water, before the product dries.

Application Wet the substrate to saturation point (dry rough cast or concrete paving withbrushed finish). Remove excess water: substrates must not be sweating.

Apply KATYMPER PISCINE to a minimum thickness of 8 mm, manually (using atrowel or float) or mechanically using a plaster projection machine.

• When working on the vertical surface, continue spreading the plaster to awidth of approximately 20cm over the floor surface also, in order to ensurecontinuity with the horizontal section.

• On the floor surface, apply KATYPER PISCINE in adjacent widths ofapproximately 50 cm, from the walls towards the centre of the concreteslab.

• Plane the KATYMPER PISCINE with a smoother and make the adjacentwidths uniform.

• Wait until the product begins to set (the product turns matt and can nolonger be indented by finger pressure), then rub the surface with a slightlymoist sponge float (rinse regularly).

• As you progress, chase out any occluded air bubbles and immediately fillwith plaster, if necessary.

• Be careful to obtain a smooth, homogenous and regular finish.

For further instructions, consult the KATYMPER PISCINE application guide.Finishes • Smooth finish: after finishing with the sponge float, let the KATYPMPER

PISCINE set (for a few hours, depending on the temperature).Remove any protuding grains from the surface by brushing the walls with abrush with medium-hard nylon bristles, until you obtain a smooth facing.

• Sanded finish: this finish gives the smoothest surface; it is vital forhighlighting the blue-coloured grains.

Take particular care with the evenness of the coating.Let the KATYMPER PISCINE harden for 24 to 48 hours.Sand the coating uniformly, taking care to completely remove the layer ofKATYMPER PISCINE laitance which comes to the surface as a result of the float-finishing.

HardeningCuring process Protect from dehydration during the hardening phase.

In high temperatures, spray (after the KATYMPER PISCINE has dried) with a jet ofwater regulated to the mist setting. This re-hydration must not be carried out in fullsun or on an overheated substrate. Avoid allowing the water to stagnate on thecoating: this may cause whitish marks (deposits of free lime from the mortardissolved in the water).

Sanding24 to 48 hours after the coating has been applied.

Filling with water24 to 48 hours maximum after application, in a continuous manner withoutinterruptions, in order to guard against marks and colour anomalies on the coatingas it hardens.Keep the walls wet if the filling of the pool takes longer than one day.

During the first filling after application of the coating, the pH rises above the valuerequired for swimming pool water (by 7). This phenomenon is natural with ahydraulic binder-based coating and is dependent upon the water supplied (pH andmineral content) and on the dimensions of the swimming pool.In order to optimize the curing and hardening of a new coating:

• do not carry out an chemical treatments on the water during the first weekafter filling;

• Then, only carry out water disinfection treatments during the followingweeks (3 to 6 weeks, until the pH has stabilized; time varies in accordancewith the characteristics of the water supplied);

• Then, adjustment of the pH can be commenced, taking care at the sametime to control and adjust, if necessary, the mineral content of the water(TA and TH between 10 and 15°F).

Restrictions of use Some advice concerning swimming pool treatments and maintenance.

• Only use «special swimming-pool» products in the doses recommendedby the manufacturer.

• Do not put concentrated products (disinfectants, pH correction products,etc.) directly in contact with the coating. For example, do not pour themalong the walls or leave them to dissolve on the bottom.

• «Shock» treatments can harm the coating.• Some electrolytic type water treatment systems can stain the coating:

consult the manufacturer.• Do not use copper sulphate as an anti-algae or hydrochloric acid as a pool

cleaner.• General recommendations for optimal treatment of swimming pool water

advise keeping the water at its chemical equilibrium (pH around 7, TA andTH between 10 and 15°F).In the case of water with a low mineral content, it is therefore necessary tocarry out a re-mineralization in order to achieve good water treatment andensure the durability of the KATYMPER PISCINE, which is a hydraulicbinder-based product with sand and limestone fillers.In the case of water with a high mineral content, any use of very acidicdescalers must be limited to zones where deposits are visible on thecoating. Also, it must be controlled (the use of gel-type products ispreferred, in order to avoid the risk of the product running, compliance withdilution instructions, contact time before rinsing, etc. in accordance withthe manufacturer’s recommendations), in order to allow removal of thedeposits without damage to the coating.

• In the case of automatic pH adjustment, be sure to check the adjustmentsand have the device regularly calibrated. If not, an excessive injection ofpH corrector could lead to a fall in the pH and demineralization of thewater, which is likely to damage the coating.

• Like all mortars used in a similar environment, KATYMPER PISCINE canbe subject to the development of micro-organisms (algae, fungi, etc.)which sometimes manifest by the appearance of marks of different colours(brown, grey, green, etc.). These proliferations of micro-organisms arecaused by agents exterior to the product and need suitable treatment(algaecide, biocide, bactericide, etc.).

• To clean the existing coating, do not use metallic tools (brush, scraper,etc.): as this may leave a deposit of iron particles, which could leave tracesof rust due to oxidation.
