WATER DISPERSIBLE POLYMER PRIMER

Description
ECOSCREED AP1000 Primer is a milky white dispersion of synthetic polymer dispersion in a water base, designed to give maximum penetration into the substrate for enhanced bond. ECOSCREED Primer AP1000 has been specially formulated to be used with ECOSCREED cementitious materials and is available in 10 or 25 litre containers and 1 tonne IBC's.

Benefits
- Water based, non toxic and safe to use
- Provides excellent adhesion on a wide range of substrates
- Ensures enhanced bond strength
- Suitable for use with all bonded ECOSCREED cementitious products
- Prevents air problems that can spoil the finish of pumpable screeds

Substrate Preparation
Substrates should be hard, sound and free from dirt, dust, grease, paint, plaster laitance and other contaminants which could provide a barrier to adhesion. Where the substrate has been subject to chemical contamination then advice should be sought from the ECOSCREED Technical Department. The preparation of the substrate by mechanical methods such as shotblasting or scabbling is recognized as being the most effective way to provide a good mechanical key prior to applying cementitious bonded screeds.

Primer Appilaction
A priming system is recommended as follows:-
Sealing/ Bonding Coat : 1part primer to 2 parts water (allow to fully dry)

Particularly absorbent or porous surfaces may require a further sealing/bonding coat to prevent air rising from the substrate and affecting the final finish in pumped screeds. ECOSCREED AP1000 Primer should only be applied with a soft broom ensuring that all puddles, ponding and drips are fully brushed out prior to screeding or tiling applications. Allow the primer to fully dry.

Properties
Appearance : Milky white liquid MFT : 3%
Specific Gravity : 1.03 kg per litre Solids content : 50%
pH : 8.0 - 9.0 Drying Time : Overnight*

SOLVENT FREE EPOXY DAMP PROOF MEMBRANE

Description
ECOSCREED Epoxy DPM is a two component solvent free epoxy resin based damp proof membrane specifically designed as a residual moisture suppressant for concrete to allow the early installation of moisture sensitive flooring in fastrack building programmes. One or two coats may be applied depending on the degree of dampness present in the sub-floor. The product is available in grey and red colours to allow control of uniform coverage.

Design Use
As a surface damp-proof membrane.
As a moisture suppressant on concrete and cementitious screeds
As damp tolerant primer for concrete and resin screeds.

Benefits
- Provides surface damp-proof membrane
- Coloured to monitor progress
- Low viscosity, easily applied
- Excellent adhesion
- Low temperature cure
- Solvent free, low odour
- Allows Rapid 24 laying of floor coverings to power floated concrete.

Typical Properties
Colour : red and grey
Viscosity : 500 cps @ 20ºC
Pot Life : 45 minutes @ 20ºC - 90 minutes @ 10ºC
Application rate : 3 Sq.m/kg - first coat (depending upon substrate texture) - 4 Sq.m/kg - first coat (depending upon substrate texture)
Adhesive Strength : 3.6 N/Sq.mm (concrete failure) (to damp concrete)
Curing : 5 hours @ 20ºC touch dry - 12 minutes @ 20ºC hard dry - Flexural Strength 64 N/Sq.mm
Water Absorption : < 0.2% after 7 days immersion

Susbtrate Preparation
ECOSCREED Epoxy DPM can be applied to concrete 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. Moisture testing of the substrate in accordance with BS8203 shall be carried out on new concrete floors. A sub-floor moisture reading of 95%RH can be accommodated by ECOSCREED Epoxy DPM. If the readings exceed this figure, then the floor must be allowed to dry out further.

Mixing
Pour the contents of the CURING AGENT component into the BASE container and thoroughly mix together by mechanical means until a uniform colour and consistency is achieved.
NB: Larger packs may be site batched using a mix ration of 2 parts by volume BASE to 1 part by volume CURING AGENT.

Application
Apply a first coat of ECOSCREED Epoxy DPM, RED, by brush, roller or airless spray, to the prepared substrate at a nominal rate of 3 Sq.m/Kg. Within 24 hours apply a coat of Grey material at a nominal rate of 4 Sq.m/Kg and 'blind' out with an appropriate 16/30's silica sand. Excess sand may be swept or vacuumed from the surface following a minimum of 12 hours @ 20ºC or 24 hours @ 10ºC.

Packaging
ECOSCREED Epoxy DPM is available in 15Kg pack sizes.

Storage & Shelf Life
Store in dry conditions at temperatures between 10ºC and 25ºC. Do NOT expose to freezing.
Minumum shelf life of 12 months when stored in accordance with rccommendations.

Limitations
Do not apply at temperatures below 2ºC
Do not apply on surfaces which have condensation or standing water

Health & Safety
Avoid contact with eyes and skin. Wear protective gloves, goggles and overalls during use. Wash off with soap and water if the material comes into contact with the skin.
