Mortars and Plasters
A range of cement-based mortars suitable for where a high depth of repair or levelling to concrete is required, as well as compatible plasters for use with Newton’s range of meshed waterproofing and damp proofing membranes.
Rapid Set and High Strength mortars and plaster
Mortars and plasters are essential ancillaries in the installation of effective waterproofing. For example, our cement-based structural mortar HydroSeal 203-RM has been instrumental in a wide range of waterproofing projects. Mostly used for durable repairs to concrete structures, it can also be used to repair bridges, floors, footpaths, roads, runways, and decks.
Mortars such as this are also regularly used for concrete levelling where a completely flat and uniform surface is required quickly. With the addition of water, they create a rapid-curing mortar which will set quickly and be safe for foot traffic within hours.
Benefits of using Newton mortars
HydroSeal 203-RM is a single component, fast setting mortar. It is polymer modified and fibre reinforced with a high adhesion and compressive strength. The mortar can be installed up to 100mm deep, or it can be mixed with sharp sand to create a screed with a maximum depth of 300mm.
Overall, HydroSeal 203-RM provides the following benefits:
- Strong and durable even at sub-zero temperatures
- High bond strength greater than concrete
- Sets in ten minutes for quick application
- Resistant to 10 bar water pressure
- Non-toxic when cured and suitable for use in reservoirs or other drinking water containment areas
- Resistant to acid gases, chloride ions, and sulphates
Limelite Whitewall One Coat Plaster
One Coat Plaster is a pre-blended, one coat plaster that is applied like a standard backing plaster but gives the finish and durability of a first-class finishing plaster. Whitewall One Coat is resistant to humidity and is therefore ideal for use with cavity drain membranes.
Tough, hard wearing finish
Whitewall One Coat provides a tough finish that is highly resistant to impact and casual damage.
Versatile
Can be used on a wide range of traditional substrates such as solid brick and stone. It can also be used on walls that have previously suffered from damp or flooding.
Easy to use
Limelite Whitewall One Coat Plaster is lightweight, easy to mix and is applied using standard plastering tools and techniques without any additional training requirement. It is applied like a backing plaster yet has the finished appearance of a finishing plaster
No need to paint
Limelite Whitewall One Coat Plaster makes it easy to achieve a smooth, matt off white finish that can be left unpainted for a natural look. This saves on decorating costs.
Responsibly sourced
All of our products are manufactured in the UK and certified under BES 6001 Responsible sourcing. Tarmac was the first company within the cement and lime sectors to be awarded the BES6001 ‘Excellent’ rating across its entire product range.
Tarmac Whitewall is the recommended plaster for application to Newton Meshed Membranes. Whilst Tarmac Whitewall is a single coat application to most substrates, to Newton meshed membranes it is a two coat application. A subsequent smooth finish coat product will also usually be applied prior to decoration. Please read the installation instructions of the membrane the Whitewall will be applied to for further information
