Rising damp and White Rot: A case study

white rot rising damp Rising damp is a common problem that affects many homes and buildings. It occurs when moisture from the ground travels up through porous building materials, such as bricks, mortar, and timber. Moisture in timber frames that have been affected by flood water, can also be trapped behind plaster sheet, tiles and architraves. This remains sight unseen. When this moisture reaches the timber frame of a building, it can cause a number of problems, including the growth of white rot.

TWA Woodcare Range Rationalisation

Since Preschem has taken over the distribution of the TWA Woodcare range in July last year, we were always intending to rationalise this range. If you were not already aware, there were a few duplicated products. These products are identical in formulation in every sense, just different in name only. Which products you may ask?

UPDATE 31st March: The Victorian Government has put the state under Stage 3 lockdown effective immediately from this date. Preschem still continues to operate under these restrictions and is fully compliant with the requirements imposed by our state Premier. Please note that Preschem is protecting the health of our staff and is therefore not accepting walk in sales from the general public. This is to ensure we can supply our utility customers throughout this crisis, so they can keep the lights on.

We are still here to assist you and can be contacted to place orders or for technical support on 03 9532 0679.


UPDATE 27th March: We are still open for business, but we are no longer accepting walk in counter sales from the general public. Unfortunately, we have had to stop this, as we’ve had customers ignoring our signage to not enter if showing any flu like symptoms (yes, heavy coughing is a flu like symptom). Should you wish to obtain product directly from us, please ring through your order and pay via credit card. We will then courier it to you (additional charge). This will ensure we are able to operate through this crisis.


23rd March: Dear customer, as you are aware the State and Federal Government response to the COVID-19 crisis has been to shut down all non-essential services within Victoria. Preschem supplies the electrical distribution and transmission industry with power pole preservatives to ensure the continued supply of electricity. This is a critical essential service. Preschem is open for business and continues to manufacture our products to support our utility customers. We will continue to do so for as long as it’s deemed safe.

We are monitoring the unfolding situation closely and should the circumstances change, will update you on the website as soon as possible.

We have taken steps to minimize potential exposure to COVID-19 with our staff including such measures as daily temperature checks, personal separation and improved hygiene practices. Where practical, we are allowing our staff to work from home.

We would appreciate that if you need to visit our office, that you do so only if it’s urgent and that you display no signs of flu-like symptoms. We may request that you allow us to take a temperature reading with an IR thermometer and will ask anyone with an unusually high temperature to leave the building.

But we are also able to despatch orders door to door and encourage you to use this as a priority.

We wish all of our community to remain healthy and safe through these difficult times.

Videos by Drive Marine Services

Preschem has an old and very knowledgable retail customer who supplies Preschem products for timber boat maintenance. Dave and Scott at Drive Marine Services certainly know their way around timber boats, and have developed a number of specialised marine grade epoxy and acrylic products that perform brilliantly in this tough environment. Dave is also the star of a number of short but informative YouTube videos on the products he sells, including some showcasing Preschem Products.

And the interesting thing about these products for the marine market is that they’re mostly compatible with many of the Preschem timber preserviatives. Head over to the Drive Marine Services website for more details, or give them a call on 02 9533 5470.

Deck Preparation for Staining and Oiling

Sooner than you think, the warm weather of spring and summer will return. Everyone will be looking forward to entertaining on, or simply enjoying their timber deck. So that means it’s time to start planning the deck preparation as part of its maintenance. After all we all want our decks liking like it did when it was first installed all those years ago.

But before you start oiling you have to prepare the deck to get a great result. This means removing the dirt, grime and the UV weathering that has built up. The best means to do that is to use Preschem’s Grey Deck Cleaner. This is a mild oxalic acid based cleaner that restores your deck to the “as new” colour. This doesn’t take long and you’ll need an hour or so. And I’ll let you in on a little secret. When I did my deck at home last year, it had been 2 years since I last done it. So I’m going to take you through this process step by step, with photos along the way.
