HIGH PERFORMANCE OXYGEN CROSSLINKING POLYURETHANE
FINISHING SEALER

Description
ECOSCREED PU Sealer is a high performance 100% polyurethane sealer for wood floors or for the finishing and sealing of ECOSCREED RAPID 24 and ECOSCREED Terrazzo pumped screeds. The sealer is a one pack system and provides a low odour, fast drying and hardening finish thereby allowing a Rapid 24 return to service with the minimum disruption to the client. The product will protect the newly installed pumped screed from absorbing oil or other common spillages.

Design Use
As a sealing or finishing coat to either pumped cementitious screeds or any type of wood floor. Sealing and coating of the ECOSCREED range of pumpable screeds. Specifically designed for where enhanced chemical resistance is required and where the screed needs to be protected from oil of other chemical spillages. As a hygienic, easily cleanable coating for walls, ceilings and floors.

Benefits
- May be applied direct to surface of cementitious screeds
- Available as a clear sealer with a silk finish
- Low odour
- Excellent resistance to water, oils, skydrol, petrol, dilute acids and alkalis, many solvents etc
- Very good adhesion to concrete
- Hygienic and easily cleaned

Typical Properties
Colours : Clear
Material : 100% Polyurethane
Drying time : 2 hours at 20ºC

Substrate Preparation
ECOSCREED PU Sealer can be applied direct to the surface of ECOSCREED cementitious screeds 24 hours after their application or on concrete that is hard, sound and free from dirt, dust, oil, grease, paint, plaster, laitance or other contaminants which could act as a barrier to adhesion. Concrete substrates shall have a residual moisture content of below 6% and temperatures of 10ºC or above. Wood floors should be suitably sanded to provide a smooth clean surface prior to application. Remove all fine dust prior to application of the finish. On wooded floors it is extremely important that all previous polish and cleaning residues are removed to ensure good adhesion and correct cosmetic appearance of the finish. Previously waxed wooden floors will require specialist preparation.For advice please contact our Technical Department on 01372 842 102

Mixing
The product is a one pack system and should be thoroughly stirred with a drill and stirrer prior to use.

Application
Apply using a suitable applicator and pad at a rate of approximately 75 - 80m² per 5 litres
Apply a minimum of 2 coats and allow the first coat to cure for a minimum of 2 hours at 20ºC prior to applying the second coat.

Packaging
ECOSCREED PU Sealer is supplied in 5 litre containers.

Coverage
Covarage is dependent upon porosity but as a general rule a 5litre pack should cover approximately 75 - 80m²

Storage & Shelf Life
Store in dry, frost free conditions at temperatures between 10ºC and 25ºC. The material has a minimum shelf life of 12 months when stored in original, unopened containers in accordance with the manufacturers instructions.

Limitations
Do not apply to wet or uncured concrete surfaces
Do not apply at temperatures of below 10ºC

Health & Safety
Avoid contact of the material with the eyes and skin. Wear appropriate gloves, overalls and eye protection during use. Please refer to the Material Safety Data Sheet for additional information

HIGH PERFORMANCE WATER DISPERSIBLE EPOXY COATING

Description
ECOSCREED WD 250 is a high performance, water dispersible epoxy coating for the treatment of floors and walls and has been specifically designed to be compatible with the ECOSCREED range of pumpable levelling compounds. The coating is both user and environmentally friendly, containing no solvents and having a very low odour during application. It can be easily applied by brush, roller or airless spray to provide a decorative abrasion and chemically resistant coating of excellent durability.

Design Use
Sealing and coating of the ECOSCREED range of pumpable screeds where enhanced chemical resistance is required. As a hygienic, easily cleanable coating for walls, ceilings and floors.

Benefits
- May be applied to dry or damp surfaces
- Available in range of colours
- Low odour
- Excellent resistance to water, oils, skydrol, petrol, dilute acids and alkalis, many solvents etc
- Very good adhesion to concrete
- Hygienic and easily cleaned

Typical Properties
Colours : Red, Grey (other colours available on request)
Pot Life : 80 minutes at 20ºC and 120 minutes at 10ºC
Volume Solids : 65%

Substrate Preparation
ECOSCREED WD 250 can be applied to surfaces that are hard, sound and free from dirt, dust, oil, grease, paint, plaster, laitance or other contaminants which could act as a barrier to adhesion. Where the floor has been contaminated by chemicals or mineral acids, the specific advice of the ECOSCREED Technical Department should be sought on 0836 582 033 or 01372 842 102. The preparation of substrates by mechanical methods such as shotblasting , scabbling or diamond grinding are considered the most effective means of providing a suitable mechanical key. Concrete substrates shall have a residual moisture content of below 6% and temperatures of 7ºC or above.

Mixing
Pour contents of the BASE component into the CURING AGENT container and mix by mechanical means until a uniform colour and appearance is obtained. For the first coat the mixed material may be thinned by the addition of up to a maximum of 5% by volume of potable water.

Application
Apply by brush, roller or airless spray to the prepared surface at a nominal rate of 0.20 to 0.25 kg/m² per coat, equivalent to a dry film thickness of 100 - 125 microns. A minimum of two coats is recommended with the second coat being applied after a minimum interval of 18 hours curing. Ensure good ventilation after application as this will speed up the physical drying stage of the curing process. Should a non-slip finish be required then a suitable silica sand should be scattered onto the first coat whilst it is still wet. The following day any excess sand should be swept or vacuumed from the surface prior to the application of the second coat.

Curing
Allow to cure for a minimum of 48 hours prior to normal traffic. Full chemical resistance will be achieved following 7 days cure at 20ºC

Packaging
ECOSCREED WD 250 is supplied in 15kg packs

Coverage
A 5kg pack is, depending on the smoothness of the substrate, sufficient to treat 10 - 12.5 m² of surface with the recommended two coat treatment giving an overall dry film thickness of 200 - 250 microns. (15kg pack pro rata)

Storage & Shelf Life
Store in dry, frost free conditions at temperatures between 10ºC and 25ºC. The material has a minimum shelf life of 12 months when stored in original, unopened containers in accordance with the manufacturerers instructions.

Limitations
Do not apply to wet or uncured concrete surfaces
Do not apply at temperatures of below 6ºC
In poorly ventilated areas forced extraction must be provided.

Health & Safety
Avoid contact of the material with the eyes and skin. Wear appropriate gloves, overalls and eye protection during use. Please refer to the Material Safety Data Sheet for additional information
