Universal Mortar & Fillet Seal is a Thixotropic, Fibre-reinforced, multi-purpose cementitious mortar which can be used as a mortar for waterpoofing, levelling and re-profiling. It can also be used as a Fillet Seal at wall to floor, wall to wall and wall to ceiling junctions.

Supplied in 25kg Bags inside a Bucket which can be used for mixing, available in Grey colour only.

Description

Universal Mortar

Universal Mortar & Fillet Seal is a single component, thixotropic, fibre reinforced, polymer and micro silica modified cementitious mortar which cures rapidly to produce a high performance, fair faced levelling coat, render and profile mortar with enhanced waterproofing properties. Universal Mortar & Fillet Seal can be used as a mortar for waterpoofing, levelling and re-profiling. It can also be used as a Fillet Seal at wall to floor, wall to wall and wall to ceiling junctions.

Typical Applications:

  • As a Mortar for waterpoofing, levelling and re-profiling

  • As a Fillet at wall to floor, wall to wall and wall to ceiling junctions

  • Foundations, slabs, retaining walls etc.

  • Drinking water structures

  • As a High build repair mortar

Product Benefits:

  • Factory batched mortar which provides consistent quality.

  • Wide range of applications from a single product.

  • Ideal for use with specialist waterproofing systems such as our Tanking Slurry Products.

  • High bond strength which ensures monolithic performance.

  • Fibre reinforced to give improved tensile and impact strength.

  • Dense matrix provides excellent protection from ingress of acid gases, moisture and chlorides.

  • Suitable for horizontal, vertical and overhead applications.

  • Economic mortar which generally requires no substrate inter-layer priming.

Preparation

Substrate Suitability:

Universal Mortar & Fillet Seal can be applied to Concrete, Brick and Structural Blockwork

Surface Preparation:

Active water leaks must be stopped using Water Stop Plugging Compound prior to application of Universal Mortar & Fillet Seal.

Areas to be levelled, filled or repaired must be clean and free from all unsound materials.

For localised repair, saw cut or cut back the extremities of the repair locations to a depth of at least 10mm to avoid feather-edging and to provide a square edge.

Break out the complete repair area to a minimum depth of 10mm up to the sawn edge.

Brickwork and Blockwork:

Remove by suitable means all loose pointing, any remaining render or plaster, wood, dust, grease, oil, organic growth or other foreign materials that may cause contamination or adversely affect adhesion properties.

Concrete:

If there is any exposed steel present, apply two coats of suitable corrosion inhibitor to the exposed steel by brush.

Remove all loose material and surface latencies, i.e. dust, oil, grease, corrosion by products and organic growth, preferably by using wet grit or water blasting techniques or equivalent approved methods. The strength of the concrete sub-base must be a minimum of 20 N/mm².

Priming:

On all prepared substrates thoroughly dampen the surface with clean water prior to application.

If the substrates are of a highly porous nature it is recommended to apply 1 coat application of SBR at a 1:1 dilution with water, allow approximately 1 - 2 hours drying time prior to application of Universal Mortar & Fillet Seal.

Mixing:

  1. Place between 3.00 - 3.75 litres of clean water into suitable mixing bucket.

  2. Using a slow speed electric paddle mixer (400 - 600rpm), gradually start to add the powder whilst mixing.

  3. Ensure all the powder is added.

  4. Mix for approx. 3 minutes to achieve a creamy lump free consistency.

  5. If required, add a small amount of water to obtain the correct consistency depending on application.

Application

Application Methods:

Universal Mortar & Fillet Seal is applied by gloved hand, trowel or suitable spray equipment.

As a Fillet Seal Application:

Using bricklaying or pointing trowel, apply a minimum 25mm Fillet at wall / floor, wall / wall and if necessary wall / ceiling junctions.

Ensure Universal Mortar & Fillet Seal is pressed firmly into the chase at the wall / floor and joints at wall / wall, whilst still green form a “bottle” cove and feather for 50mm - 100mm along the adjacent surfaces. Achieve a smooth finish to the fillet.

Where excessive stress concentrations can be expected at the wall / floor joints it is recommended a dilution of SBR at 1:2 with water used as the gauging solution.

By Spray Application:

Use traditional wet mortar spraying equipment and processes.

On Vertical Surfaces:

Universal Mortar & Fillet Seal is to be applied at a minimum of 5mm up to a maximum of 15mm layer thickness in one working operation.

Apply the product by trowel using a standard rendering technique or spray technique ensuring to remove any trapped air. If more than one coat is required to obtain the desired build, ensure that previous layers are well keyed and stable but not fully set prior to application of the subsequent layers.

Final profiling to a high quality can easily be achieved using a steel float after allowing the surface to stabilise.

Wooden or plastic floats and damp sponges may also be used to achieve the desired surface texture.

On Horizontal Surfaces:

Place Universal Mortar & Fillet Seal onto the horizontal surface, compact and strike off to a maximum layer thickness of 50mm.

After initial hardening, final profiling can be achieved to a high quality using a steel float or a brushed finish using a broom to increase skid resistant properties.

Soffits and Overhead Applications:

When using Universal Mortar & Fillet Seal as a levelling coat, apply at a minimum of 5mm up to a maximum of 10mm layer thickness in one working operation.

Apply the product by trowel using standard rendering technique or spray technique ensuring to remove any entrapped air.

If more than one coat is required to obtain the desired build, ensure that previous layers are well keyed and stable but not fully set prior to application of subsequent layers.

If sagging occurs during application, Universal Mortar & Fillet Seal should be completely removed and reapplied at a reduced thickness on to a correctly prepared substrate.

Localised Repair Applications:

Apply Universal Mortar & Fillet Seal to the prepared substrate by gloved hand or trowel. Care must be taken to ensure that an initial 5mm - 10mm thickness of mortar is well placed and adhered prior to building up to larger depths.

Thoroughly compact the mortar on to the prepared substrate and around any exposed reinforcement if present. If necessary, support with shuttering to allow for compaction when working to reveals, etc.

The application thickness achievable is dependent upon the substrate.

For repairs which require multi-layer application, it is important to esnure that previous layers are well keyed and stable but not fully set prior to the application of subsequent layers. No inter layer priming is required.

Final profiling of a high quality can easily be achieved using a steel float after allowing the surface to stabilise.

Application Conditions:

Do not apply Universal Mortar & Fillet Seal in temperatures below 5°C and rising or above 35°C (ambient and substrate).

Curing:

Curing procedures should be strictly adhered to. It is important that the surface of the mortar is protected from strong sunlight and drying winds with either a suitable curing compound, polythene sheeting, damp hessian or similar.

Coverage:

A 25kg bag of Universal Mortar & Fillet Seal covers approximately 1.40m² at 10mm thickness.
