Hydrostatic Two parts Epoxy Primer Primeseal MC

Hydrostatic Two parts Epoxy Primer Primeseal MC

Product Information

Primeseal MC 20L two parts kits, price includes GST and freight to Sydney Metropolitan areas only.

Primeseal MC (Moisture Cure) is a water based, epoxy waterproof membrane.
It is a high performance, versatile, two-part, water based, hydrostatic pressure resistant, waterproofing barrier membrane coating suitable for most types of porous and semi-porous surfaces including green (newly laid) hardened concrete and damp surfaces.
It cures to form a strong, waterproof, hydrostatic pressure resistant and water vapour pressure barrier and is formulated for application on to damp, newly laid concrete and most other construction surfaces.
It is suitable for potable (drinking water) applications and can withstand up to 25 metre head of water pressure.
It's versatility makes it also ideal as a primer for waterproofing membranes, paints, industrial coatings and as a bridging coating for normally incompatible coatings.
It's standard colour is light grey but is also available in off-white and black (minimum quantities apply).
It has very low VOCs and meets the 'Green Star' environmental  criteria.

Uses 

  • It is formulated for demanding waterproofing, sealing and priming applications including:
  • Waterproofs and seals damp and green (newly laid) hardened concrete.
  • Waterproofs negative (inside) surfaces.
  • Waterproofs positive (outside) surfaces.
  • Waterproofs above and below grade surfaces.
  • Low water vapour pressure barrier. (Prevents or minimises bubbling of membranes due to vapour emmissions from the substrate).
  • Waterproofs basements, retaining walls, lift wells, cellars etc.
  • Waterproofs tanks and water retaining structures, i.e. concrete or cementitious structures.
  • Excellent primer for subsequent Wrimco membranes, paints and industrial coatings.
  • Seals and primes timber floors prior to applying waterproofing membranes and other coatings.
  • Seals concrete floors before laying timber floors.

Suitable Surfaces 

It is suitable for most construction surfaces including:
Concrete, green (newly laid) hardened concrete, cement, cement render, brick, block work, masonry, Hebel, timber, FC sheeting, CFC sheeting, plasterboard and painted or coated surfaces.
Damp surfaces - but freedom from standing, running, seeping water, saturated substrates and continual dampness is essential.

Additional Uses: 

  • A general and universal primer on most types of substrates for membranes, paints and industrial coatings.
  • A sealer coat over bitumen surfaces to allow the application of solvent and water based waterproofing membranes and other coatings.
  • A sealer over damp surfaces to allow the application of urethane based waterproofing membranes.
  • An intercoat bridging coating to allow the application of incompatible coatings.
  • A primer and sealer of concrete, cement, cement render, timber, brick, block work, FC sheeting, CFC sheeting, plasterboard and bituminous surfaces.
  • A primer over bituminous and torch-on membranes so that they can be top-coated or re-membraned.
  • Top coat over Crystoflex to provide an attractive colour and finish.

Specification 

The information contained in this product data sheet is typical but does not constitute a full specification as conditions and specific requirements may vary from project to project. The instructions should be considered as a minimum requirement but the applicator or contractor must use their skill, knowledge and experience to carry out additional works as may be necessary to meet the requirements of the project. Specification for specific projects should be sought from the Company in writing.

Limitations 

Being an epoxy, it has low flexibility and is NOT designed to bridge live cracks or expansion joints. 
It can be effectively used for sealing inside (negative) wall surfaces, but this method should only be employed if waterproofing the outside (positive) surfaces is not feasible or inaccessible.
Application Temperature Limitations: Between 10°C and 35°C.
Curing Limitations:
Temperature must exceed 10 C and relative humidity must be less than 85%. 
If these conditions are not present then artificial ventilation and heating should be used.
In confined, enclosed areas ventilation should be used to circulate air to enable the evaporation of water from the product.
It is not a permanently trafficable membrane, but suitable for service or trade foot traffic.
Where the product is to be used in hydrostatic water pressure applications, the surfaces on which it is applied must be and remain structurally sound and stable.

Benefits and Advantages: 

  • It is user and environmentally friendly, solvent free and has negligible odour.
  • Very low VOCs and meets the 'Green Star' environmental criteria.
  • Can be applied to green (newly laid) hardened concrete.
  • Can be applied to damp surfaces.
  • Is a barrier against low water vapour pressure.
  • Suitable for contact with potable (drinking) water. Conforms to AS4020-2000.
  • Non-toxic and non-flammable.
  • Can be applied in sensitive areas.
  • Withstands up to 25 meter head of water.
  • Easy to apply by brush, roller, squeegee and spray.
  • Quick drying.
  • Has excellent adhesion.
  • Excellent water barrier.
  • Can be used as a primary waterproof barrier on rigid surfaces.
  • It will not re - emulsify.
  • Seals over most existing coatings.
  • Can be used to seal both the negative and the positive sides of the substrate.
  • Compatible with all Wrimco waterproofing membranes and floor coatings.
  • Acts as a bleed sealer over bituminous surfaces.
  • Excellent primer over torch-on waterproofing products.

Precautions in Use: 

It is water based and contains very low VOC's and is considered safe to use. However, observe good hygiene and safety practices. The wearing of gloves and goggles against splashes is strongly recommended. Good ventilation is recommended and avoid contact with skin, eyes and mouth. If poisoning occurs contact Poison Information Centre. If swallowed DO NOT induce vomiting, give plenty of water to drink and seek medical advice. If in eyes thoroughly flush with clean water, holding lid open to ensure any product maybe flushed away. If on skin wash with soap and water.

Priming and Surface Preparation: 

Good preparation is essential. Surfaces must be sound, stable, dry, clean and free of dust, loose, flaking, friable material and substances that may diminish adhesion.To achieve a maximum bond existing coatings, membranes and adhesives should be removed so that the product can bond directly to the substrate. 
Holes, gaps, blowholes, honeycombed surfaces and non-structural cracks should be suitably filled and made sound using a suitable non-shrink mortar. If the surfaces needs to be bagged, a bagging mix as follows should be applied to the surface.
Mixing:
Before combining, each component should be individually well stirred. Then mix equal portions of Part A and Part B thoroughly to a homogeneous  consistency before application. Avoid undue aeration. Only mix enough product that can easily be applied within 1 to 2 hours or pot life, which may be effected by prevailing climate conditions.
Bagging Primer Mix:  
If a bagging mix is desired or required due to the condition of the substrate, it is important that the following mixing sequence is followed. Before combining, each component should be individually well stirred. Then mix equal portions of Part A and Part B thoroughly to a homogeneous  consistency. Add 30% water and thoroughly mix and then add sufficient 3:1 sand: cement mix to the Primeseal MC liquid to form a brushable or rollable consistency. Apply to surface, by brush or roller ensuring that the product is worked well in to the surface and that all holes, voids, indentations are properly covered. Allow to dry.

Application: Apply by brush, nylon broom, roller, squeegee or spray, in 2 or more coats, at the recommended application / coverage rate, to produce a uniform, solid coating. The wet film thickness per coat should approximate 330 microns (0.33mm).
If applying Primeseal MC to dry concrete, cement, blockwork or Hebel it is recommended that the surface be lightly pre-dampened with a fine water spray before application.
The product should be worked well in to the substrate ensuring that all holes and voids are adequately covered. Avoid pinholes.
The first coat may be thinned up 20% to achieve good penetration depending upon the type, density and porosity of the surface. Generally, this should not be required and if possible should be avoided. However, if diluted, coverage must be adjusted (increased) to achieved net usage and curing times may increase. If in doubt as to the adequacy of coverage, apply a further coat. Allow each coat to dry before applying the next.

Coverage: The stated average coverage rate may vary depending upon type, condition, porosity, texture of the surface and application technique.As an effective waterproofing membrane or barrier against low water vapour pressure:
A minimum of 2 coats applied at 3 m² per litre per coat. 
If this coverage is not achieved in two coats, an additional coat should be applied.
The minimum dry film thickness should be 0.33mm.
The waterproofing properties are enhanced when used in conjunction with suitable Duram waterproofing membranes.

Coverage per Kit Size for 2 Coats:
4 Lt. Kit for 6 m²
10 Lt. Kit for 15 m²
20 Lt. Kit for 30 m² 

Drying and Curing

Drying and curing of the product is affected by type, dryness and porosity of the surface, temperature, humidity, ventilation, climate conditions and application technique and therefore drying and curing can only be given as a guide. It is essential  that the membrane must not be damaged in any way including when applying subsequent coatings. Damp and cold surfaces will increase drying times.
Storage: Store in a cool, dry area away from direct sun light. Ensure unused product is sealed properly. Keep out of reach of children. Clean Up: Wet spills must be promptly be cleaned up with water, but should be avoided as it is difficult to remove entirely from surfaces.
