Renders & Decorative Finishes

Rendering over painted render and backgrounds

Painted backgrounds aren't suitable for rendering directly over, so the paint will first need to be removed

Repairing cracks in external rendered walls

More noticable cracks in monocouche render can be repaired to retain a similar level and texture to the existing render

Protecting render from algae growth and other contaminants

Whilst monocouche render is low maintenance, like any other building facade it is not immune from the gradual buildup of organic growth and dirt

Applying render over existing masonry

Existing masonry is designed as a finish in its own right but may not be suitable to accept a direct application of render

Rendering on surfaces with poor key

Renders are not adhesives and require a combination of suction and mechanical key to bond to the substrate

Insulating and rendering a timber-framed construction

Although timber frames are treated, they are vulnerable to rot and need to be kept in a warm, dry environment

Rendering over existing render

We do not recommend rendering over existing render due to the large amount of unknown factors affecting its suitability

Using a decorative finish over existing render

Applying a decorative finish over existing render is the preferred option when refreshing the appearance of existing render

Removing and replacing existing render

Removing existing render is a large undertaking and is likely to result in damage to the substrate

External Wall Insulation

Insulating structural frames

A proven fast-track method of concrete or steel frame construction. Infill walls need to be provided and the structural frame kept warm and dry

Refurbishing decaying concrete facades

Concrete structures often show signs of unsightly degradation over a period of time and can eventually affect the structure

Insulating single-skin construction

Single-skin construction requires significant attention to detail at openings to avoid moisture tracking around seals and into the inner face

Upgrading non-traditional housing

Early non-traditional or system built housing wasn't built for the long-term and doesn't meet today's thermal standards

Upgrading the thermal insulation of a building

Initially a choice needs to be made regarding where to position additional insulation in the structure

Remodelling facades

Changing the use of a building often requires physical changes to its external fenestration, completely reshaping its structure

Using mesh reinforcement in external render

Rendering inappropriate surfaces

Renders are sometimes required to be applied to cover up bad construction practice and inappropriate surfaces

Tile Fixing Products

Tiling onto floating floors

Floating floors are those which are used to improve insulation and/or to reduce noise. As they are not attached to a rigid substrate, they require extra care when tiling onto.

Tiling onto green screeds or concrete

Newly-laid screeds take time to stabilise, so tiling onto the screed too early can end in disaster as the screed shrinks during the drying process.

Tiling with natural stone

Tiles classed as 'natural materials' vary immensely from ceramics in appearance and application requirements

Working with natural stone - protection/maintenance

Natural stone tiles require careful preparation prior to grouting, and need regular maintenance

Strengthening a wooden floor for tiling

Because wooden floors naturally bend, bounce and expand, tiles can end up cracking under the pressure if installed incorrectly.

Tiling over tiles

Tiling over existing tiles is possible, but there are a few things to first consider.

How to lay large format floor tiles

When tiling with large tiles extra considerations must be made to ensure they are fixed level and firmly in place

Application of webersys protect tanking kit

Protecting a water-sensitive substrate

Tiled areas in kitchens, bathrooms and showers can be subject to high humidity or water, which means the a waterproofing layer needs to be applied before laying tiles.

Tiling on wood

Tiling onto wood comes with a number of considerations regarding substrate strength and flexibility of adhesive used. Image courtesy of Schluter Systems Ltd.

Tiling with an uncoupling membrane

Since uncoupling membranes are available in many different types, it is important to be aware of issues you may face when tiling.

Tiling uneven floors

Preparing an uneven floor prior to tiling involves a number of steps to ensure a smooth and even finish

Tiling onto anhydrite screeds

Anhydrite screeds have become quite popular, but tilers must be aware of a number of potential problems.

Tiling with underfloor heating or under tile warming

Underfloor heating can cause an array of issues if not tiled onto correctly, from cracking due to heat expansion to damaging wires with your trowel.
