More than ever before, you want peace of mind when choosing the materials to build your home. Amongst the many options for exterior cladding – plaster is an option. Perhaps you are considering plaster because you like the look, like the textural appeal or perhaps you need to make your extension or renovation match your original building.
Substrates including polystyrene and all masonry surfaces such as concrete, concrete block, AAC concrete, brick, clay and stone, straw-bale, rammed earth, and fibrous cement sheeting can be plastered over. It all comes down to your budget and which product suits your build.
WHAT PLASTERERS DO
Plasterers are required to learn a wide range of skills on the job, from selecting and measuring the right materials to applying and creating the required finish. There are two exterior plaster specialities in New Zealand (some professional plasterers
choose to specialise in both):
* Solid plaster: This is where the contractor applies protective and decorative coats of sand and cement-based plaster.
* PPCS (Proprietary Plaster Cladding System): The contractor installs a variety of exterior cladding substrates and finishes them with coats of plaster modified to form a ‘system’ with the particular substrate.
Most plastering contractors have a variety of services on offer so it pays to check that the contractors you consider have the skills and experience to complete your job to your satisfaction. The type of services that most registered plasterers offer will usually fit into the following categories:
* Old and new houses * Ugly Brick or Blockwork, painted or unpainted. * Garden walls * Boundary fences * Block bases of houses * Ponds and water features * Barbeque areas * Indoor/outdoor fireplaces * Plasterboard * Hardiplank * Planter boxes * Cornices * Fibrous sheets, niches, domes, fireplaces * Concrete steps and terraces * Detail bands letter work or negative detail * Letterboxes.
This is one of the most exciting projects you will ever undertake! Finding a good Plasterer will remove some of the stress of your build. They should be able to manage the full aspect of your plastering. Generally, your Plasterer will need a set of plans and they can provide you with a Quotation. Look out for systems that come complete with a Construction Systems Manufacturers warranty and for a plasterer that has an Applicators warranty.
RENOVATIONS AND REPAIRS
Is an extension on your mind? Has your teenager driven into the side of your house? or have you been affected by a natural disaster and have an Insurance Claim? Your chosen Plasterer should be able to give you some ideas on how to make it as good as new. If you are wanting to modernize then your Plasterer should be able to offer you different options to meet your taste and budget.
Is it time for an update to your homes exterior look? Maybe you have been stung by the Leaky Home Syndrome. Whatever your reason for considering a plaster reclad you should look for someone who is a Licensed Building Practitioner (LBP) and who has the experience and knowledge to assist you.
Every project is different and therefore the cost will vary. Factors that affect your costing are things like:
The size and shape of your home. How much work is required. The extent of any post reclad redecoration work required. Whether any alteration work is required or is to be undertaken at the same time. Whether new joinery (i.e. window and door joinery) is being installed. Access (i.e. is the house on a step site requiring extensive scaffolding).
The recladding costs for a stand-alone mid-sized (3-4 bedroom) house fall into the following ranges: –
Remedial Design: $6000 – $11,000 Building Consent: $6,000 – $10,000 Building Consultant: $2,500 – $4,000 Building Work: $200,000 – $500,000
A general rule of thumb with your exterior plastered home is a full house repaint every 10-12 years. Extra care is required when painting over your texture to ensure a weathertight covering. A ‘Render Spec’ which gives you a detailed description of how your Plasterer plans to manage your project should be received. This covers what system will be used, what products will be used, and a timeframe of works. Look out for extra costs which may not be quoted like scaffolding costs.
Since ancient times, plaster has been used as an Interior & Exterior wall material. Unique, natural based systems which when applied correctly can give you a ‘Standout’ feature in your home. There are various options available to achieve this – Earthen Clay and Marrakesh Lime based plasters are popular.
Clay earth plaster is a practical, environmentally friendly alternative to cement, gypsum and acrylic plasters. It is compatible with the “breathable” construction recommended for both historic and new buildings.
* Clay plaster naturally controls the interior climate by absorbing and releasing moisture in response to environmental changes.
* Walls are warm to the touch in Winter and cool in Summer
* It contains NO VOC’s (Volatile Organic Compounds)
* Does not provide a “home” for mould growth.
* No potentially harmful gases from petroleum-based additives or formaldehydes.
* The natural movement of water vapours through clay plaster releases Negative Ions into your home. Negative Ions have been proven to evoke feelings of well- being.
Are you a plaster home owner? If you have found that moisture is getting into your home it is best to act quickly. If left untreated, the moisture damage will eventually lead to major structural failure and this is not cheap to fix – think in the hundreds of thousands of dollars to fix. Living in a damp moist environment can cause severe health problems for you and your family. If your home is leaky, find a Plasterer that can advise and guide you through the Weathertight Homes Resolution claim process. Even if your home is a relatively new build – say built in the last 10 years or so, you may still be able to present a claim to the Weathertight Homes Resolution Service for the cost of your repairs.
