How to put on your Bloccs Protector

Please read the following instructions carefully before using your Bloccs Protector.

These instructions must be followed to use your protector safely and to ensure that the watertight seal is effective.

The decision to take a bath, shower or to enter a swimming pool is taken at your own risk. Medical advice should be sought to ensure that the activity will not affect your injury.

As your Bloccs protector is made from natural rubber, you should remove any sharp jewellery and take care not to puncture the cover with your fingernails. If there appear to be any sharp or rough edges on the cast you should cover these with tape or a stretchy bandage, particularly if it is a fibreglass cast.

To put the Bloccs protector on easily, turn half the protector down so that the seal is at the bottom. Put the first half on and then slowly roll up the remainder until the seal is in the correct position at the top, above the bandage or cast.

Gently remove any air from the protector by holding the seal open at the top and flattening the protector against the cast, moving upwards until all the air has been removed. When bathing or swimming, this can also be done by gradually lowering the limb into the water; the pressure of the water will force the air to the top of the protector. Gently pull the seal away from the skin to remove the air before submerging.

Warning – natural rubber can become slippery when wet. See instructions on use of full or short leg Bloccs protectors. Please also see instructions for using a Bloccs protector at a swimming pool.

Using your Bloccs protector at a swimming pool

Bloccs protectors have been designed using the same type of seal found on a dry suit which is used for water sports.

The seal will be effective for gentle use in a swimming pool or spa pool for someone who is recovering from an injury.

You should not jump or dive into the pool. The protectors have not been designed for diving or snorkelling.

All air should be removed from the Bloccs protector before entering the water by massaging the cover upwards towards the seal to release any trapped air. This can also be done by gradually lowering the limb into the water, the pressure of the water will force the air to the top of the cover, gently pull the seal away from the skin to remove the air before submerging.

We recommend that the Bloccs protector is regularly checked during use to ensure that the seal has remained watertight and is still comfortable.

The protector can be worn for up to 60 minutes providing it is still comfortable to wear, does not feel too tight and it is checked regularly.

Use Bloccs Leg Protectors

Natural rubber can be slippery when wet. You should use a bath mat in the shower or bath and ensure that you step onto the mat. A non-slip mat or towel should be placed on the floor for when you get out of the bath or shower.

If you are using a Bloccs leg protector to enter a swimming pool, you must ensure that all the air is expelled from the cover, as described previously. As rubber can be slippery when wet you should not walk around the side of the pool wearing a Bloccs protector.

The protector should be put on just before entering the pool and removed as soon as you leave the pool.

Care should be taken when using swimming pool steps as they may be slippery. You should ensure that you hold on tightly to the hand rail at all times when using steps.

Bloccs Protector Care

The Bloccs protector is subject to wear and tear but should last for about 4 weeks of normal use.

Over time, all latex rubber loses its ability to stretch, becoming hard and brittle. This process of perishing or degradation occurs due to exposure of the rubber to the environmental factors of light, heat and ozone which induces chemical changes in the latex.

The protector must be checked before each use to ensure that there are no signs of damage or fatigue.

If the protector has deteriorated or becomes damaged in any way a replacement should be purchased.


Ever wondered what happens if you get your cast wet?

Well, it’s not good news:

If you have a Plaster of Paris Cast and it gets wet, it quickly turns into a soggy mess and won’t hold the bone in place.

If you have a Fibreglass Cast and water seeps under the cast, not only does this weaken the cast, it can soak the padding under the cast, which can then cause irritation and infection of the skin can develop.

We’re all keen to get rid of our cast as quickly as possible, wearing a Bloccs Waterproof Cast Cover can keep your cast dry for showering, bathing and swimming, helping you recuperate quickly.


The storage temperature should be kept below 26 degrees Celsius and the protector should be stored away from heaters. In extreme cold the protector may become stiff; this is not permanent and warming will correct this.

Moist storage conditions should be avoided. The protector should be protected from prolonged exposure to light, in particular direct sunlight and artificial light with a high UV content.

Avoid contact with copper and copper- containing alloys.

Keep away from naked flames.

Contact should be avoided with solvents, oils and greases.


The Bloccs protector can be washed in warm water and should then be dried carefully inside and out.

If you dust the inside lightly with talc, this will make the Bloccs protector easier to put on.

Do not tumble dry the protector or dry on a radiator.

How long will a Bloccs Cast Cover last?

We recommend checking the protectors before each use to ensure that there are no signs of damage or fatigue.

Customer Testimonials

We've helped thousands of people find relief while they are recuperating and we're an ACC approved vendor. 
Meet a few of our customers and see how Cast Covers has impacted their recovery:

'"We have just returned from a 2 week holiday in Rarotonga. Before we left our 8-year-old daughter fell off her scooter and broke both bones in her arm. This was a huge blow for us as our holiday was all booked and we were nearly packing to leave. I went online and google searched cast covers and thankfully you guys came up! I was absolutely blown away by how amazing this product was … no more plastic bags, yay !!! Our girl was able to enjoy the holiday just like the rest of us, even diving and jumping into the pool and snorkelling out in the lagoon for hours on end. We have just had her cast removed but will be holding onto this wee gem for the future, thanks so much!!!  I can’t stress enough how awesome your product is. Even after using it every day for 6 weeks in plaster it’s still in absolutely pristine condition." 

Jenna Sayer, Queenstown

" I would just like to congratulate you not only on the great service, but also the great product i.e. Waterproof Protector. My wife received hers yesterday, she has been suffering from an ulcer on the lower part of her leg which has required heavy bandaging twice a week for some time, and today had the first carefree shower that she has been able to have for many weeks. We will both be eternally grateful for this great product. Thank you so very much."

Neville & Dian Butler

"Just wanted to drop you a line to let you know how I am going with my evenup. 

I have been using it every day since going from a cast into a moonboot and honestly do not know what I would do without it! Although I am still uneven due to my moonboot having a particularly large sole to it, the evenup at least reduces the strain on my other Achilles’ tendon and my hips and back. 

I have been interested to observe that few physiotherapists are even aware these are available and are very impressed with the concept on seeing mine."
