Finely Crafted Jesmonite Casting & Moulds

Here at Artisan Plastercraft, we understand the importance of a property’s façade. This is the first impression provided by a building of any type when approached by a visitor, and can mean the difference between leaving said visitor in awe, or leaving them feeling apathetic. By providing finely crafted jesmonite casting and moulds, we will be able to assist you in creating a magnificent structural exterior that is more than certain to leave guests or other distinguished individuals admiring every inch of your property’s frontage.

Our specialist jesmonite mouldmaking and casting services are available if this is what you would like carried out for your property. Contact us today by phone or email, and we will listen carefully to what you wish to have carried out, before providing a quote for what you will need completed. Alternatively, if you would like to see an example of jesmonite work we have already noted in our portfolio, please see our work on the Beaumont Hotel.

What is Jesmonite?

This may be the first question one would think when considering materials for mouldings, would it not? Jesmonite is not widely known or considered in most day-to-day work or projects which require moulds, despite being one of the few water based resins available today. It is a composite material, made from a liquid acrylic compound that binds gypsum powder. This mixture will take on the properties of plaster for 24 hours, before hardening to a substance not unlike acrylic resin.

There are several types of jesmonite available for use in either interior or exterior work projects. These range from AC100 jesmonite, which is durable and suited for general outdoor applications, to AC200 jesmonite and AC300 jesmonite, which are most used on interior spaces. AC730 is also available for architectural use, but is most suited to water features and submersed casting, as well as stone finishes.

If you require professionally crafted jesmonite casting to complete the aesthetics of your exterior space, please contact us today. One of our highly trained and experienced members of staff will be able to discuss the work you require, before our master craftsmen begin their task of providing you with the expertly made casts that will bring a stately charm to your property.

What we do

As specialists in the manufacture and installation of exterior mouldings, we will use jesmonite castings to create long-lasting external modern and period features. This simulates the natural stone and metals which would have provided the original façade for many properties in times past, either returning your exterior space to the zenith of its golden years, or giving it a grandeur equal to architectural marvels several times older.

Our jesmonite casts are available in a number of different, stunning stone finishes, from Portland or Bath, to Marble or Granite, and each mould will be crafted to the individual requirements of our customers. This ensures that you will receive exactly what you need for your property, and nothing less.

How we do it

In order to create our moulds, we use computer-aided design (CAD) to show you the exact model before any further work is carried out. This also offers us the opportunity to be as precise as fine-crafted features require, eliminating the risk of flaws in projects. From this method, we will provide any architectural feature you may wish to use for your property, from fascia coving, cornices, eaves dentils and corbels, to gallow brackets, door arches, porticos and columns.

When we are called to carry out work on your property, we will also be happy to carry out a complimentary site survey, assisting you in determining the best course of action for your planned project. The solution we use will be decided by the discoveries made in our survey, and we will provide this for you in a report after the survey is complete. This report will also contain our quote for the work your property will need, as well as advice on how to care for and maintain the jesmonite mouldings you have received.

How we work and where

Our highest quality work may be found across the length and breadth of this country, as prized features of buildings from large, private residences to palaces, embassies and art galleries. We have even carried out work for the Houses of Parliament, so we are certain that we will be able to provide the perfectly cast jesmonite mouldings you need to maintain the aesthetics of your property, exactly as you have been imagining.

Your specifications are of paramount importance to us, and with our skill and expertise, as well as your faith in us, we know that we will be able to undertake any task you require. No matter your architectural building style, or the type of finish you would like for your property, we will be able to cast it for you.

In order to discuss what you need for your own jesmonite mouldings, please do not hesitate to contact us via phone or email today. One of our staff members will be ready and waiting to speak with you about the work project you have planned for your property, before informing our fully qualified craftsmen of your requirements. They will then use this information to begin work on your own jesmonite features, completing them in the exact manner that you have asked from us.

After our initial site assessment survey, we work with you to understand the projects: objectives, challenges and then offer you workable solutions. To get a feel for our work view our grade-two listed Beaumont Hotel project.

Technique Talk

What is Jesmonite?

Its a modern alternative to original render and stonework. It has an excellent strength-to-weight ratio making it ideal for impressive structures, yet lightweight.

Why use it?

It’s flame resistant, durable and resistant to impact (therefore suited to exterior hazards). It can be used to fabricate both small and large objects. It uses a low toxic mixing process and finished products emit no toxins.

Where found?

Large public building exteriors in developed areas: theatres, hotels and retail centres.

Bit of trivia

Jesmonite decorative detailing was used heavily on the Royal Barge Gloriana for the 2012 Thames Diamond Jubilee Pageant. Decorative details included dolphins and Old Father Thames. A perfect material of choice due to its ease of form and lightweight nature.
