Frequently asked questions

You can if you wish (tape, nail, screw, cling film, plastic cap…), as long as it doesn't prevent the filter from being inserted through the nozzle.

It's preferable to wipe the nozzle before insertion to remove any residue that could stick to the filter or other parts of the Masticbox, otherwise you'd need to clean it before the next use.

Yes, all products that polymerise on contact with moisture. To make sure, check the storage instructions provided by the manufacturer: "Store in a dry place".

Exception: chemical anchor cartridges, which polymerise through the mixing of a base and a catalyst.

Yes. You can insert and store all types of cartridges without cleaning the Masticbox between two uses, as long as it's clean and free of residue from the previous cartridge on internal surfaces.

Yes. The vacuum quickly reduces the humidity inside the Masticbox and therefore very quickly stops the polymerisation of the product contained in your cartridge.

No. Use only a manual vacuum pump, identical to the one supplied with the Masticbox SADURR®.

Never use an electric vacuum pump — it doesn't allow you to control the vacuum and could damage the Masticbox components or the cartridge inside.

The valve must be stuck and adhering to the valve cap after a maximum of 3 to 4 pumps with the manual pump. The valve cap is then locked just like a jar under vacuum.

Yes. The slight vacuum quickly reduces humidity inside the Masticbox SADURR® (less air, less moisture) and therefore stops the polymerisation of the product contained in your cartridge.

Without this safety cap, we cannot guarantee optimal storage of your cartridges.

Clean each removable part with warm soapy water using a soft sponge, then dry everything with a cloth or absorbent paper before reuse.

If sealant residue remains on the walls, this doesn't affect the effectiveness of the Masticbox — except if the residue is on functional parts: the valve, the seals, the threads of either cap, or the perforated outer parts of the filter.

Warning: do not use solvent-based products, as they may damage the Masticbox.

During the manufacture of silica gel beads, some end up slightly crushed. The filter may therefore lose a few beads through the slots — these are silica gel beads which present no toxicity.

The filter is packed with a quantity of beads that stops about 1 cm from the cap closing the filter. This minimal loss does not affect the proper functioning of the product in any way.

You can use your Masticbox with full confidence and safety by following the instructions.

Yes. Place the filter in a microwave-safe container, in the centre, then run the microwave on normal mode until the beads turn orange again.

Duration: approximately 1 to 2 minutes depending on the microwave power — 600 watts maximum.

Important: the filter must never be opened. Do not use or regenerate the filter if you notice the slightest deterioration (caps, walls). Order a new filter — €8.00

When one of the filter compartments becomes entirely white/transparent, the filter becomes inactive and must be regenerated to ensure optimal storage.

Filter regeneration — 2 methods:

• In the oven: rack at mid-height, fan-assisted heat, thermostat 90°C/100°C maximum, about 1 hour or more, until the beads turn orange again.
• In the microwave: suitable container, normal mode, about 1 to 2 minutes (600 watts maximum).

Several months, provided the usage procedure is correctly applied. Do not exceed the expiration date indicated on the cartridge by the manufacturer.

Yes, all parts can be replaced without difficulty and are available individually.

Check the cleanliness of the valve, valve cap, and O-ring located in the valve cap. If needed, remove the valve and O-ring from the cap, clean these 3 parts with warm soapy water, dry them properly, then reassemble (without solvent-based products).

If the lack of adhesion persists, replace these parts:

• Valve — €1.80
• O-ring GM — €1.20
• Valve cap — €3.10

It is recommended not to leave the Masticbox in direct contact with UV rays.

If the Masticbox contains a cartridge, it's preferable to keep it sheltered from UV.

The slight vacuum created with the manual pump (which allows for a faster reduction in humidity) also forms a thermal barrier. Your cartridges are protected from extreme heat or frost, particularly when stored in a van.

Yes. It avoids throwing away still-usable cartridges and lets you make full use of the product. Fewer discarded cartridges means less waste, less packaging, and fewer material losses.

Yes. By reducing worksite waste and optimising the use of consumables, the Masticbox SADURR® fits into a responsible approach.

You can put a new cartridge in the Masticbox SADURR®, which will help preserve it under optimal conditions.

Important: the use of the Masticbox cannot replace the expiration date indicated by the cartridge manufacturer.

The commercial warranty is set out in our Terms of Sale.

The Masticbox SADURR® is made in France.

The Masticbox SADURR® is intended for all cartridge users who want to store their opened cartridges long-term:

For work involving watertight joints, rendering, bonding, or touch-ups, you often don't use a whole cartridge. The Masticbox SADURR® lets you store and preserve opened cartridges to reuse them later, without the product drying out.

It's particularly useful when working with multiple colours or different references across several worksites — you avoid waste and make material organisation easier.
