Shake the mixture, add the hardener in a ratio of 5:1 and mix in by shaking. If partial quantities are to be mixed, use the LOBA mixing container or weigh the quantities out. Can be used for 2 hours after mixing.
The surface must be professionally sanded. The floor must be dry and free of any old coatings, oil, grease, wax, silicone, sanding dust and other impurities.
The optimal processing conditions are room temperature +15°C to + 25°C, floor temperature +15°C to +22°C, rel. humidity 40% to 75%, material temperature +18°C to + 25°C, max. wood moisture 12%, sufficiently ventilate working rooms.
In order to prevent parquet damage, the room temperature should be set to the annual average expected for the use of the product.
To reduce the risk of excessive swelling, we recommend applying a maximum of 2 roll applications per day.
Transfer material to a LOBA varnish bucket before applying.
Shake the contents well.
Observe general and, if necessary, product-specific occupational health and safety regulations. Further information can be found in the GISCODE-related operating instructions which are available under www.wingis-online.de.
This product is part of the LOBA and Wakol “Connected Systems”. The approved combinations with Wakol parquet adhesives may be found in the "Connected Systems" Matrix: www.loba.de/connected-systems

Thinner / Mixing

The product is ready for use and must not be reduced!

Application tool / application rate

LOBA roller Deluxe 120 or LOBA roller Microfaser 100-120 or LOBA roller FiberTech / 100-120 ml(g)/m² = 8-10 m²/l(kg)

Drying time

Can be carefully walked on, intermediate sanding can be performed and can be varnished over after no less than 4 hours.
Light use after 24 hours.
Full use and covering possible after 5 days.
The floor can be covered earlier by using LOBA Cover 400, for details see the TI for the product.
Drying times are valid for +20°C and 50% relative humidity.

Intermediate sanding

Able to recoat without intermediate sanding within the first 24 hours. After this time, an intermediate sanding is necessary. An intermediate sanding before the last application will improve the optical appearence of the surface.Use LOBASAND perforated pad P120 or finer, alternatively Sanding Net P120 or finer.Carefully remove dust before overcoating.

Use on parquet and hardwood floors:

Prepare and prime the substrate properly.
Allow the primer to dry as specified.
Apply by roller.
Dry.
Intermediate sanding.
Apply second coating layer by roller.

Use on cork:

Seal only after the adhesive has set adequately.

Untreated natural cork:

Apply three layers of coating by roller.
Allow the first layer to dry overnight (reduces the risk of granule swelling).
Intermediate sanding before the final application.

Prefinished cork

Observe the cork supplier's instructions. If suitable for recoating, apply one or two layers of coating after an intermediate sanding

Renovation / recoating of old coatings

Basic cleaning with CareRemover. Use a rotary disk buffing machine and a LOBASAND SpecialPad green. Care product residues must be completely removed. Even small amounts of residue can adversely effect the bond of the coating. Clean with clear water (neutralise). After drying, carry out a thorough intermediate sanding. Apply coating in one or two layers by roller

Coloring tip

To achieve a brightening/whitening effect on light-coloured substrates, we recommend adding LOBA Whitener according to the technical information of the product. In order to minimize color reactions with tannins, the first layer of the paint must be applied to untreated cork in the delivery form without color additive. Subsequent drying overnight is necessary.
To achieve a color intensification on natural cork and brownish and reddish colored cork floors, we recommend adding LOBA Amberizer according to the technical information of the product.

Linoleum and PVC:

Thoroughly clean using LOBA CareRemover according to the technical information. A single-disc machine with a green LOBASAND special pad must be used. Residues from care products must be completely removed, as even small traces of residue can prevent the finish from adhering properly. Wipe (neutralise) with clear water. Allow to dry. Factory finished coverings must be matted with a LOBASAND Polishing fleece after thorough cleaning (1 polishing fleece is sufficient for approx. 20 m2). Roll on a layer of finish.

Suitable product combinations

We recommend using a primer:

To minimise side bonding and to seal off wood constituents, e.g. in exotic timber.

EasyPrime
VivaPrime
2K Intensive
PrimaSeal Plus (contains solvent)

Additives

The range of application, properties and appearance can be extended by combining with LOBA additives. Please refer to the respective technical information of the additives for possible combinations, detailed application information, and drying times.
