Looking for answers about our jointing products?
Here we have collected the most frequently asked questions we receive from our customers,
about the jointing products Easy Fugesand, Quicksand and Strength Joints (L-series).
Easy Jointing sand
No, it is important to water the joint enough so that it is completely soaked. You may want to. “dig up” a bit of the joint and see if the joint is soaked.
Repairs are easily made, clean the joint where the jointing material has disappeared and add Easy jointing sand in the normal way. Alternatively, you can compress the joint by hitting a piece of wood with a rubber mallet on the pavement – this simulates a vibratory plate.
As long as the Easy grout fills the entire joint, it acts as a weed inhibitor.
Yes, Easy Jointing Sand sticks to the pavement.
We haven’t experienced it, but Easy jointing sand temporarily becomes soft and elastic when wet, but the joint still remains a solid cohesive joint and hardens when it dries again.
Yes, you can use Easy Jointing Sand for paving bricks, but always remember to start with a small area. This way, you ensure that you are happy with how your paving stones and jointing material visually work together.
The white foam that appears when you water Easy jointing sand means that you have activated the adhesive. Keep watering until there is no more foam.
Look for the foam. When you activate the binder, some white foam will appear. Continue until no more foam emerges from the joint. If necessary, you can also lift up the joint to check that the water has entered the joint completely.
After the Easy joint has been wetted, allow the joint to dry. When the joint is dry, it is hardened and ready for use.
Lithomex advises against the use of sandstone and ceramic tiles for all hard joints, as sandstone is generally highly absorbent, which can result in an undesirable appearance. Ceramic tiles are generally very thin and “move”. If you still want the benefits of a Lithomex hard joint with your sandstone or ceramic tiles, you should create a test area to see if you are satisfied with the result. All other paving stones can be used for Easy jointing sand as long as they fulfil the technical data in the Lithomex Easy brochures.
Easy jointing sand is available in 3 standard colours, natural, grey and black.
Yes, Easy jointing sand is frost and salt resistant.
No, water helps compacted Quicksand into the joint and does not damage the joint.
Yes, once the vacuum bag in the bucket is opened, the process is initiated, which means the entire bucket must be used.
Yes, Quicksand can be used in your pavement around your pool. If you use chemicals to clean around your pool, for example against algae, be aware that it can dissolve the Quicksand adhesive. You may want to test your chemical in an inconspicuous place.
Quicksand bonds/adheres slightly to the coating, but the strength of Quicksand comes more from its compressive strength than its adhesion. It is therefore important that your joint depth is at least twice as deep as the joint is wide, as this ensures that the joint sand stays in the joint.
Lithomex advises against the use of sandstone and ceramic tiles for all hard joints, as sandstone is generally highly absorbent, which can result in an undesirable appearance. Ceramic tiles are generally very thin and “move”. If you still want the benefits of a Lithomex hard joint with your sandstone or ceramic tiles, you should create a test area to see if you are satisfied with the result. All other paving stones can be used for Quicksand as long as they fulfil the technical data in the Lithomex Quicksand brochure.
Quicksand is a hard, firm and permeable joint, so heavy rainfall is no problem.
24 hours at an average bottom build-up and average temperature of 20 degrees. Higher temperatures accelerate the process. The pavement can be walked on when the surface is hard.
Lithomex does not recommend using sweepers/suction machines on areas with Quicksand. You can also test whether your sweeper can be used on a Quicksand surface.
No, Quicksand does not require any special tools or certificates. All you need is Quicksand, water and a broom or mop.
Quicksand comes in 3 standard colours, natural, grey and black.
For larger quantities, we can deliver in special colours.
Yes, Quicksand is frost and salt resistant.
The requirements for joint width and joint depth can be found in the brochure for the specific product. It is important to adhere to the minimum and maximum joint depths and widths, as well as the installation instructions, as the strength and weed control effect is only achieved if the joint is properly packed.
Strength joints (L-series)
Yes, as long as the technical data is still met. For example, the new L-series joint may need to be half the stone depth in traffic.
Yes, clean the joint and load your L-series joint in the normal way.
If your joint width for the L-series exceeds 50 mm, contact Lithomex for advice.
To achieve the extreme strength we have in L50, you can’t use a adhesive that can withstand water before it’s hardened. Hvis man tilføjer vand til L50 vil den ikke opnå den rette styrke, og man kan risikere et ”mælkehvidt” slør.
In connection with professional work in Denmark with epoxy products, such as Lithomex’s L-series, you must pass an epoxy and isocyanates course. Other countries may have other rules. At the time of writing, there are no requirements for non professional consumers.
No, only add the amount of water specified in the instructions and only at the time specified in the instructions. If you don’t follow the instructions, you risk a joint with weaker strength and possibly a milky white veil on the joint.
In order for weeds to grow in your weed-free joint, there must be a hole in the joint where the weeds have grown through. Therefore, always make sure that your grout is properly packed so that there are no gaps. Weeds may appear on top of the joint, which can be caused by a little soil and airborne seeds lying on top of the joint. This is easily solved by sweeping the pavement.
As long as the joints are intact.
No, once our jointing material has hardened, it is non-toxic.
After 24 hours the pavement can be walked on and is fully cured after 7 days at an average temperature of 20 degrees.
If the L-series grout is exposed to water/rain during curing, you may risk a milky white veil on the grout and stones.
In its uncured state, epoxy is considered harmless if:
No, the L-series does not emit any harmful substances in the hardened state.
No, hardened epoxy is harmless. Landfill in hardened condition – EAK code 08 04 09* Waste adhesives and sealants.
Yes, sweepers/suction machines are no problem for Lithomex L-series (strength joints).

The standard colours for the L-series are natural, grey and black.
Special colours are available.
Yes, Lithomex strength joints can withstand frost and salt.
Common to all our products is that all requirements for joint widths and joint depths can be found in the technical data section of the brochure. It is important to observe all technical data and carry out the jointing according to the instructions. If the technical data and instructions are not followed, the joint may not pack properly, resulting in too low a density and therefore too low a strength.
Yes, some water needs to be added to the L10/L20 to achieve the right strength.
Always follow the instructions in the brochure.
