"If you’ve got a big property or just a massive list of chores, this 12L Marolex is a total lifesaver. I was sick of constantly refilling my smaller sprayer, so the extra capacity on this one is huge. Even when it’s full, it’s comfortable to carry, and the pump action is smooth as."

Overview

The 12L Marolex Sprayer is the professional-grade partner for your Wet & Forget concentrates, designed for those who value efficiency & durability. Engineered to provide maximum coverage with minimum effort, this high-capacity sprayer ensures you can treat your entire home, driveway, or roof in one seamless application.

By moving the weight of the liquid to your back with ergonomic, padded shoulder straps, you maintain better balance and control while applying moss and mould treatments or garden fertilisers. The robust pump mechanism ensures a consistent flow rate, allowing you to coat surfaces thoroughly for the most effective results. Whether you are treating a weathered fence or a mossy brick path, this 12L unit provides the volume required to complete the job in a single session without the interruption of constant refills.

Protect Your Plants

If you are treating areas near garden beds, water your plants thoroughly before application to create a protective barrier, and rinse them down again once you have finished to wash away any accidental overspray.

Mix your concentrate.

Fill the 12L tank with water and add your chosen Wet & Forget concentrate according to the label's dilution ratios.

Pump to build pressure.

Secure the backpack straps comfortably and pump the side handle until you feel firm resistance in the application wand

Spray for complete coverage.

Using the extendable wand, coat the targeted surface thoroughly until it is visibly wet, ensuring the formula can penetrate deep into the growth or grime.

Love this product, makes cleaning the house so easy and effortless and fast

Product works well on pine decks, only requiring medium scrubbing with the long handled brush. However with hardwood decks such as our purple heart deck it does require A LOT of scrubbing. Had to get knee pads and scrubbed on all fours for half a day with a hand held brush. I think I expected it to be easier to be honest but still happy with the outcome.

You had me until the last few words you have to scrub it. Any cleaning product would work if you scrub it

Have waited 2 months for something to happen, still waiting.

This product did not work. I followed the instructions to the letter and been waiting over a month now and nothing has happen. Will not buy again.

are you spose to brush webs away first ...cause they are everywhere ...i want them gone first ....and will this KILL them or just a barrier ?

Amazing stuff! Extremely easy to clean the windows with a quick spray, wipe and rinse. No hard scrubbing is needed. My husband and I got out windows done on our 100m2 house in about 15 minutes. Used with the extending window cleaning pole, this stuff makes window cleaning a breeze.

Fantastic product, spray, light scrub, rinse and done. So easy. Commonsense is required - it contains chemicals, rinse to stop processing

Wet and Forget, you have stopped all of the arguments in our household regarding streaky windows! The new product Window Witch is the best product ever, we washed our windows at the weekend with no streaks at all! First time ever!

I wouldn’t be without this product! It makes washing my doors and windows so quick and always with a perfect result. Could never go back to doing my joinery any other way!

Frequently Asked Questions on Sprayer - 12L Marolex Back Pack (Pump)

Can I use this sprayer for all Wet & Forget products?

Yes, this sprayer is perfect for our concentrated formulas that do not have their own reach nozzle (like Rapid Application)

Does this sprayer require a lot of maintenance?

To ensure longevity, always rinse the tank and wand with fresh water after every use, especially after using weedkillers or salt-based products, to prevent residue build-up.

Can I reach a second-storey roof with this wand?

The Marolex sprayer provides excellent pressure, but for very high peaks, we recommend using our Rapid Application, which features a nozzle that reaches up to 8 metres.

Is the sprayer safe to use around my pets?

The sprayer is simply a tool; safety depends on the product inside. Once you have applied your treatment and the surface is completely dry, it is most likely safe for pets to return to the area.
