Installation and Maintenance

CUSHIONS

Robert Plumb’s standard Sunbrella Taupe cushion covers are removable and can be machine washed in cold water (less than 100°F/38°C). Depending on wash load size, use normal amounts of mild laundry soap and allow fabric to air dry.

For general or light cleaning, brush off any loose dirt, prepare a cleaning solution of 2 ounces (1/4 cup) mild soap per gallon of lukewarm water (less than 100°F/38°C). Use a sponge or a soft bristle brush to clean allowing cleaning solution to soak into fabric, rinse thoroughly to remove all soap residue and allow fabric to air dry.

DOORMAT

The natural coir matting used in our doormats is susceptible to swelling when exposed to water i.e. rain, hoses etc. To overcome this we offer two variations:

1. Maude Doormat (Outdoor)

2. Maude Doormat (Indoor)

The Maude Doormat Outdoor allows the natural expansion of the coir fibres to take place without altering the function or affecting the aesthetic appearance of the doormat.

We do stress that if the doormat is to be placed in an outdoor environment, only the Maude Outdoor Doormat be selected. Robert Plumb accepts no responsibility for warping due to exposure to water for the Maude Doormat Indoor. Please note that when dry, the mat will shrink back to its original size.

If a client wishes to use an indoor frame in an outdoor situation, an outdoor sized coir mat will replace the indoor mat. This will create a necessary gap between the mat and frame to allow for the coir fibres to expand when exposed to water.

LETTERBOXES

       Stainless Steel –

316 stainless steel is reputed for its unparalleled anti-corrosion quality when compared with other grades of stainless steel. It is widely used in marine applications, therefore also known as marine grade stainless steel. 316 stainless steel does however require maintenance/cleaning to look its best. Without regular maintenance, the stainless steel may become discoloured over time, impairing its appearance. This brown discolouration is referred to as ‘tea staining’;  however this does not affect the structural integrity or longevity of the material. Any tea staining can be removed with a mild abrasive cleaner while minor scratches can be removed using a Scotch Brite pad in the direction of the grain. Tea staining occurs most commonly near salt water areas but wind exposure, pollution, and higher temperatures can also create environments where tea staining may occur.
Robert Plumb stocks a great product called Rapelle which is a Stainless Steel cleanser and protector which will increase the longevity of the original condition of your stainless steel.

Copper –

“Patina” is the tarnish that forms on the surface of copper and is the result of atmospheric corrosion. This does not affect the structural integrity of your letterbox. It is generally a bright green colour when well established, but may initially be black before turning green.

Timber –

The Robert Plumb timber letterboxes are made with New Guinean Rosewood. If left to weather naturally the timber will turn a silver or grey colour. During the weathering process hairline cracks may appear however this does not affect the structural integrity of the letterbox. If you wish to prevent the weathering process we recommend oiling the timber with a water based penetrating oil such as Resene, available at Resene.com.au.

Locks –

Please note our locks will require maintenance over time. Please take care when installing the letterbox to ensure no sand, cement or gravel enters the lock, as this will impair the working parts. Never build the wall around the letterbox, if possible inset integrated letterboxes after completion of the wall.  We recommend every 6 months unscrewing the lock and barrel from the inside, lightly scrub with warm soapy water and let air dry before replacing it and applying a small amount of lubricant (Graphite Powder or WD 40).

Replacement Keys –

Every letterbox will come with a corresponding key for the lock. Please record the 3 digit number found on your key as this is the only way to get a replacement.  Robert Plumb uses Australian locks which most specialty lock smiths will keep on file. Keys can be copied using this unique number. Please contact your local lock smith.Please note Robert Plumb letterboxes are NOT water proof.

STAINLESS STEEL PRODUCTS

All Robert Plumb stainless steel products are constructed with marine grade 316 stainless steel (unless otherwise stated).

316 stainless steel with its unique metallurgical composition, is reputed for its unparalleled anti corrosion quality compared with other grades of stainless steel. It is widely used in marine applications, therefore also known as marine grade stainless steel.

316 stainless steel also requires maintenance/cleaning to look at its best, just like many other materials. Without regular maintenance, stainless steel may become discoloured over time, impairing its outlook. This brown discolouration is referred to ‘tea staining’, which does not affect the structural integrity or longevity of the material. Any tea staining can be removed with a mild abrasive cleaner and warm soapy water. Any minor scratches can be removed by rubbing with a Scotch Brite pad in the direction of the grain.

TIMBER  PRODUCTS

Unless otherwise stated, Robert Plumb timber products are constructed with New Guinea Rosewood. As with any timber product they are affected by natural weathering when exposed to the environment. The weathering process will turn the timber to a silver colour. However the original furniture colour can be retained by applying a rich penetrating timber oil, such as Feast and Watson Outdoor Furniture Oil ‘Clear’, every six to eight weeks. Smoothness of the timber can be retained by lightly sanding the horizontal surfaces with fine grade sandpaper as required.

Leaching occurs naturally in timber products and can cause light staining to the surface on which the timber is placed. Surfaces affected by leaching can be cleaned with a bleach and other cleaning products containing Oxalic acid.
