Cracks and tears in concrete can cause your well to leak. Metal, in turn, can rust, corrode and also leak. Do you want to avoid such problems? Then it is best to protect it with a water-resistant coating.
Depending on the condition of your concrete or metal, you may need to repair the surface first. With concrete, you can do this with a quick cement or even better with a 2-component epoxy filler. This way, you can start finishing the surface.
In the case of metal, it is best to use a polyester-based putty. This may or may not need to be reinforced with glass fibres. A handy fibre-reinforced paste is V11. This can be coated after only 20 minutes.
As for the coating itself, it is best to use a completely odourless coating. After all, you do not want to be caught out by harmful vapours from the well.
With coatings, you have the choice of 1 or 2-component products. 1K means that your product is ready for use immediately. A disadvantage is the maximum layer thickness that can be applied in one go. This material needs 'air' to harden and the thicker you apply this layer, the slower it will dry.
With 2K, we speak of a resin and the hardener. You therefore have to add both together and stir them. Then you start a limited processing time. The strongest advantage is that you can apply the product in any desired layer thickness. Sometimes it is recommended to reinforce the seams. This is best done with a glass fabric tape. You place this between your two layers of coating. Our coatings are never hard, they keep their 'elasticity' which allows them to adapt perfectly to the substrate. Coatings are suitable for applications in permanent water contact. They are UV resistant and chemically resistant to most diluted acids and alkalis.
