For intensive grease stains on concrete patios, side walks or driveways, a special wrap may be required.

Since the wrap acts by blending into the substrate and then drawing the stain out as it dries, it’s best to make sure the stain and surface are dry before applying the poultice. The dry surface will optimize the absorption capacity of the wrap and its effectiveness.

Wrap products are often described as having a pancake consistency that you pour directly over the grease stains. Then, as the wrap dries, it draws the residue out of the concrete. After the compress is completely dry, simply sweep it away and dispose of it.

It often happens that after removing the compress, the surface stained with grease should be washed with a liquid for removing grease stains from concrete. An oil and grease stain remover such as Conlix or Conlix-Bio is exceptionally easy to apply as it does not require additional equipment, putty,  or plastic coating. It is enough to pour the liquid on the fat stain and then wash it off with the liquid itself by using water. The final choice between a compress or a fluid is of course yours.

In most cases, one application of a degreaser to remove oil and grease will also remove the deposited grease stains from the concrete. However, some heavy grease stains on concrete may require to repeat the application several times.

When the compresses dry, cracks appear on them. This is perfectly normal. A network of cracks on the entire surface of the compress is a signal that the compress is completely dry. Then it is safe to use a broom or a stiff bristle brush and dustpan to sweep the dried wrap. As mentioned above, you will probably also need to treat the stain with one of our Conlix or Conlix-Bio liquids. Only liquids of this type will keep the concrete in good shape.

For stains smaller than 2 meter square of grease-stained concrete, 1 litre of Conlix should suffice. The product is also available in a 20 litre canister that can clean up to 40 metre square.
