HydrEpoxy - water based Epoxy waterproofing membrane
PRODUCT DESCRIPTION
Shelter HydrEpoxy 300 is a water based two component epoxy polyamide coating that forms a waterproof membrane or a water stop allowing the application of other coatings sensitive to substrate moisture. Shelter HydrEpoxy 300 has no noxious odours, is non flammable and compatible with fresh cement.
FEATURES/BENEFITS
- Non-flammable & negligible odour
- Can be applied to wet or damp surfaces free from running or ponding water
- Can be safely applied to freshly laid hardened (green) concrete.
- When applied to fresh concrete, acts as an effective concrete curing membrane.
- Certified as conforming to the requirements of the Australian Building Code as a waterproofing membrane.
- Easy clean-up using water
- Has excellent adhesion to most substrates including brick, masonry, concrete block, concrete and stone.
- Cured membrane will withstand 250 kPa hydrostatic pressure, which is equivalent to a 25m head of water.
- Can be overcoated using almost any decorative or industrial finishing paint.
- Safe to use in sensitive locations (e.g. around food or habitable areas) and environmentally friendly.
TYPICAL USES
TWO COATS
- As a low water vapour transmission membrane over floors to prevent water, under hydrostatic pressure, passing through to the internal.
- As a waterproofing membrane to prevent water seepage or dampness penetration through to the interior of walls and floors basements, tunnels, liftwells, retaining walls and carparks.
- As a waterproofing membrane in potable (drinking) water tanks, reservoirs and animal water troughs to prevent water leakage.
- As a waterproofing barrier in waste water collection drains and pits and on retaining walls.
- As a waterproofing membrane over freshly laid hardened (green) concrete, prior to the application of conventional carpet and tile adhesives or most paints.
ONE COAT
- As a barrier/seal coating over freshly laid concrete or wet surfaces to prevent the water or moisture affecting the drying or curing of subsequent membranes and coatings.
- As a barrier/seal coating over internal above ground walls to prevent rising damp and mildew.
- As an economical prime/bond coat over porous surfaces or Shelter HydrEpoxy 200 prior to the application of other surface coatings such as Shelter HydrEpoxy 900.
LIMITATIONS
- Should not be applied when the surface temperature is below 8°C or above 35°C or when the relative humidity is above 90%. The curing reaction of Shelter HydrEpoxy 300 will cease at temperatures below 8°C and recommence slowly and get progressively faster as the temperature rises above 8°C.
- Good ventilation should be provided, either naturally or artificially, during the drying and curing cycle. See Norcros "System Information Sheet" #001 for further information.
- Is not ultra-violet stable, unless under water.
- Is not a trafficable surface
- Do not sandwich water or solvent based adhesives between Shelter HydrEpoxy 300 (or any other waterproof membrane) and low permeability floor coverings. The covering should be sufficiently permeable to allow the water or solvents to escape through the covering. Use of cement based ceramic tile adhesives is satisfactory as the cement consumes the water in reaction.
SURFACE PREPARATION
All surfaces to be treated should be structurally sound and thoroughly cleaned free from all surface contaminates.
All existing coatings should be removed and major surface imperfections should be filled using Sheltercrete Patching Mortar and mobile and expansion joints should be reinforced as described in the Norcros Systems Information Sheet #005.
Weak concrete, poorly cleaned surfaces or fine texture finishes should be primed with Shelter HydrEpoxy 200 prior to applying the Shelter HydrEpoxy 300. The Shelter HydrEpoxy 300 should be applied in not less than 90 minutes and within the same day as the Shelter HydrEpoxy 200.
APPLICATION
Each component should be individually mixed to form homogeneous components. Thoroughly mix the two components in the ratio of 1:1 by volume, preferably using a power stirrer, until a homogeneous mix is obtained. Only mix as much as may be used within the pot life of the product and avoid excessive aeration during mixing.
AS A WATERPROOF MEMBRANE
Apply a 40-50 mm bondbreaker (masking Tape) across mobile and expansion joints and apply a liberal stripe coat across joints to 150 mm on each side of the joint.
Apply the first coat of Shelter HydrEpoxy 300 to all surfaces to be treated at a coverage rate of 3.0 square metres per litre. Allow to hard dry.
While the stripe coat remains liquid, knead in a layer of Shelter Deckweb and thoroughly wet out the Deckweb.
Apply a second full coat to all surfaces at a coverage rate of 3.0 square metres per litre.
AS A WATER STOP
Apply the first coat of Shelter HydrEpoxy 300 to all surfaces to be treated at a coverage rate of 3.0 square metres per litre. Allow to hard dry.
AS A CEMENT PAINT
Prime surfaces to be treated with Shelter HydrEpoxy 200. Only prime sufficient area as can be coated with the slurry while the Shelter HydrEpoxy 200 remains wet or tacky (approximately 60-90 minutes)
Mix Shelter HydrEpoxy 300 and add an equal volume of Portland (for grey finish) or white (for white finish) cement. Add river washed sand to achieve a slurry consistency. Note: white cement may cause the coating to be slower curing.
Apply the slurry to the surface using a trowel, roller or brush and finish using a long nap roller.
AS A PRIME COAT
Apply Shelter 200 at a rate of 5 square metres per litre to all surfaces to be treated. Allow not less than 90 minutes for the product to penetrate and within the same day before coating with Shelter HydrEpoxy 300 at a coverage rate of 12 sq. mtrs. per ltr.
CLEANING & THINNING
Thinning is not normally necessary except on very fine grained surfaces such as very high strength concrete (approximately 60 MPa) when up to 20% thinners may be added. If thinning is required use only fresh clean water.
Wash all equipment in water or water/detergent immediately on completion of work since HydrEpoxy 300 will cure underwater if equipment is left.

Dry Film Thickness
300mm theoretical dry film thickness is achieved when the product is applied at 1.5 square metres per litre. The apparent dry film thickness will reduce depending on the porosity of the substrate, however the product absorbed by the substrate forms part of the waterproofing function.
Coverage
Must be applied at a rate of 1.5 square metres per litre to achieve an effective waterproofing membrane. Minimum two coats are recommended to achieve uniform coverage.
SAFETY DATA
Shelter HydrEpoxy 300 is classified as non-toxic, non-flammable and non-explosive.
Avoid contact with skin and eyes and avoid breathing vapour or spray mist. Wear eye protection and protective gloves when mixing and using
FIRST AID
If poisoning occurs, contact a Doctor or the Poisons Information Centre. If swallowed, do NOT induce vomiting. Give a glass of water. If skin contact occurs, remove contaminated clothing and wash skin thoroughly. If in eyes, hold eyes open, flood with water for at
