Instructions for use

Preparation

 

Concure 1315 should be gently stirred immediately prior to use to ensure uniformity of the material as applied.

New concrete

 

Application to freshly placed concrete should not begin until the surface is free from water, and should not commence at all if bleed water is apparent. Concure 1315 should be applied as soon as practically possible after removal of shuttering, and whilst the concrete surface is still damp. However, any traces of laitence, grout runs or loose material should be removed.

Application

 

Concure 1315 should be applied uniformly by brush, roller or spray, with no overlap of applications. Under standard site conditions, a single coat of Concure 1315 applied at a uniform rate of 7 to 10 m2 per litre. Extra porous substrates will necessitate application of Concure 1315 at a rate of 5 – 10 m² per litre. In case of sealing and dustproofing application, 2 coats at the above range must be applied. The second coat should be applied at a coverage of 10 – 15m² per litre.

The applied film should not be trafficked until fully dry, and care should be taken to ensure that the film is not broken.

Spray equipment

 

Motorised or knapsack spray equipment, which produces a fine spray, is recommended for use with Concure 1315.

Cleaning

 

Spray equipment should be cleaned immediately after use by flushing through with water. Any residual traces of resin which are left in the nozzle may be cleaned with warm water.

Subsequent finishes

 

The resin used in Concure 1315 allows direct application of many floor coverings and paint systems, as given typically below:

• water based emulsion paints containing PVA, PVC, acrylic co-polymers or pliolite**.
• bituminous emulsions and solutions
• thin section polymer modified cement systems
• epoxy resin coatings which do not rely on penetration for substrate bond
• polyurethane coating
• water and solvent based acrylic coatings

Estimating

Coverage

 

Coverage figures quoted for Concure 1315 are indicative; and based upon application to fresh or damp concrete at the appropriate time. Care should be taken to ensure that the concrete is indeed ready to accept the curing membrane.

Application rates outside the range given below may be used if necessary, but it is recommended to first contact your local fosroc office.

Concure 1315                        :  5 to 10 m2/litre

Storage

When stored in warehouse conditions below 35°C, Concure 1315 has a minimum shelf life of 12 months.

Freezing and exposure to heat and/or direct sunlight should be avoided.

Containers should be kept sealed and airtight to prevent any reduction in shelf life.

Limitations

• Concure 1315 should only be applied within the temperature range of >5°C and <50°C.
• Any concrete surfaces which receive treatment with Concure 1315 should not be disturbed until the concrete has gained sufficient strength to bear surface loading.
• Concure 1315 should not be exposed to moving water, or rain, during application or before it has become tack free.
• Concure 1315 has been tested for bond to subsequent finishes and found to perform However, many variations of each individual type of finish exist and it is not possible to test each and every one. It is therefore recommend that an onsite bond test is carried out to determine absolute suitability.
• Not recommended for areas intended for heavy traffic or immersed

Why use polymer curing compounds?

Polymer curing compounds are ultimately more efficient and cost effective than water because they are a one time, one coat application.

The alternative, with water curing, is to constantly monitor the concrete surface and replenish with water as and when necessary. During the summer months this can easily become a full time occupation – right through the night – and is very difficult to maintain on vertical or inclined elements.

In contrast, polymer compounds are practical, very easy to apply and produce a constant, controlled rate of cure, which will underwrite the future durability of the concrete.

• more efficient cement hydration – more durable concrete

• improved surface quality – reduces permeability

• reduced plastic shrinkage – minimises cracks and repairs

The Concure range

Fosroc has developed the Concure range of concrete curing compounds to suit a variety of concreting applications.

Each Concure product is designed to meet specific site criteria; and each one is classified, according to ASTM C309, as a high performance curing compound. The range itself can be split into two distinct categories:

• General purpose –    Concure WB
  • Concure RB90

 

• Dual purpose –            Concure DPM
  • Concure 1315

General purpose

The general purpose category is designed for common concreting applications; such as floor slabs, columns etc. Both products are available in clear and white pigmented versions, the latter being of particular benefit in reducing solar heat gain on large, exposed surface areas.

Concure WB

 

• water based curing compound > 80% efficiency

• economic answer to curing problems

Concure RB90

 

• resin based curing compound > 90% efficiency

• cost effective, high performance

Dual purpose

The dual purpose compounds, as the name suggest, not only provide efficient curing, but also include equally important, permanent and supplementary features.

Concure DPM

 

• bitumen based curing compound

• provides permanent waterproofing

Concure A

 

• acrylic resin based curing compound

• acts as a permanent hardener and dustproofer

Concure 1315

 

• acrylic polymer, water based curing compound

• chemical, UV and abrasion resistant

• acts as a permanent hardener and dustproofer
