Substrate Preparation

1.11

Where so designated on the drawings, internal floor surfaces shall be treated with a trowel applied, high build, epoxy resin floor topping screed system.

1.12

General

All surfaces shall be prepared and the epoxy resin material applied strictly in accordance with the manufacturer current technical data sheet.

All work shall be carried out by an experienced contractor, who is well trained in the application of the specific, documented, floor topping screed system.

All materials used in conjunction with the floor topping screed system, shall be approved by the coating manufacturer.

1.13

Surface Preparation to existing concrete floor

All surfaces to which the new epoxy resin topping screed material is to be applied, shall be clean, sound, and free from loose material and contamination such as carpet glue, plaster, oil, paint and grease, to achieve maximum adhesion.

Dry removal of laitance and contamination by light scabbling or captive shot blasting is preferable, but where this is not feasible, treat with an acid wash, followed by thorough rinsing with water and complete drying. Dust and other debris should then be removed by vacuum brush.

All large substrate cracks and holes surface imperfections are to be primed, filled, and dry, prior to epoxy floor topping application. Where water vapour, seepage, or moisture are of concern, pre-treatment and priming with a manufacturer-approved, moisture barrier must be used.

Substrates should not have a relative humidity greater than 80% at the time of epoxy resin screed application.

1.20

Priming / Sealing

All epoxy floor topping screed surfaces are to be primed with one coat of Nitomortar 903 primer. Porous substrates are to receive two primer coats. Primer coats must be

allowed to dry before applying the epoxy floor screed topping.

1.30

Joints / Joint Sealants

All existing floor joints are to be expressed within the new epoxy resin floor topping screed system. A purpose suitable joint sealant is to be employed to address the issues of the joint movement, traffic type and frequency.

1.40

Epoxy Resin Topping Screed System

1.41

The designated floor areas shall be surfaced with a four component, coloured, durable, epoxy resin binder and filler floor screed topping. The topping is to provide a durable, chemical resistant, matt, slightly textured, anti-slip floor surface.

It shall provide the following properties, when laboratory tested @ 23oC:

Compressive Strength: / 50 MPa / (BS 6319)
Flexural strength: / 17 MPa / (BS 6319)
Cure time: / Foot traffic / 24 hours
Vehicular traffic / 48 hours
Chemical / 7 days
