Our french concrete and therefore all the creations resist the water and they are even impermeable. On the other hand, to prevent water from leaving brands on concrete, we advise you to protect it, at The French Vikings, we useTHE FRENCH PROTECT And we advise you to use the same.😉

YES ! Since the french concrete is fit for food contact. We still recommend putting a protective product: THE FRENCH PROTECTAlso fit for food contact.

🛁 How to wash and protect my creation?

Your creations will be washable as well by hand as in the dishwasher. However, beware, in the long term the dishwasher will make your concrete dull and it will lose its glow of color. The best solution remains a good sponge and elbow oil. You will already have the hand after mixing our french concrete. You can also use the protection product: THE FRENCH PROTECT. It can be used on all creations since it is fit for food contact.

🛡️How to protect my creation?

🌬️ How to dry my creation?

Prohibition to let it dry in the sun so that it dries faster. We advise you a constant temperature place ideally 20 degrees max. And above all, remember to cover your mold with a plastic to prevent water from evaporating and the concrete embroilises.

🌊 Can I add so much water to my preparation that I wish?

The addition of water is to avoid except in very small quantities. The first times the concrete seems difficult to mix but you will quickly realize that the initial dosage is enough :). To make it more liquid, simply you will simply mix, the more you mix it, the liquid will become liquid.

🎨 How to achieve a perfect mix?

To make the mixture easier, the following steps should be followed:

1. Put all the water in the mixing basin.

2. Put half the concrete and mix until a homogeneous mixture is obtained.

3. Add the rest of the concrete in small amounts and mix well between each addition (you will have to put the rest of your concrete in 4 times minimum). Your mixture must be fluid without lumps.

⚖️ I do not have a scale, how to dose my concrete?

Do not panic ! You can use a dosing glass according to the data below:

- 200g of concrete equals 150ml of water in the metering glass.

- 300g of concrete equals 225 ml of water in the metering glass.

💯 How many times can I use the mold?

The mold can be used a good dozen times without any worries! With the exception of the Freja Bowl mold which is very difficult to unmold.

📏 What will be the measures of my creation?

Visit the product cards :)

🔎 What is the composition of your products?

The French concrete is composed of Calcia white cement from Careers in Ile-de-France, dry dried river, fiberglass and fluidifier. Our pigments are natural or synthetic according to the colors and come from the south of France

🌈 Can pigments be used with another material?

They are initially recommended for use with concrete.

✂️ Is it possible to have a custom kit?

Unfortunately, we do not realize a custom kit and we do not customize existing koffrets.

♻️ Is my creation recyclable?

The concrete is recycled very well. For example, it can serve as charge in new concrete. It is also widely used in road making. It is crumped to serve as a sub-layer before flowing the bitumen. This is this last solution that allows us to recycle our waste with our partner Calcia.
