Epoxy Grouting
Epoxy grout is the king of grouts and Le Fong is the leader in installation. It is the most bulletproof grout available and the benefits are amazing. Initially it was heavily used in commercial and industrial applications due to its great features, however, over the past few years it has gained a lot of popularity in the domestic sector. A lot of people are appreciating the advantages epoxy grout has to offer and are happy to spend a little extra initially knowing they will save 10 fold in the long term.
Epoxy grouting involves installing new epoxy grout into joints that have never been grouted before. Epoxy re-grouting involves removing the old grout, cleaning all the joints and installing new epoxy grout of your choice.
Some key features of epoxy grout are:
- Extremely difficult to stain
- Repels most chemicals and acids
- Does not shrink, chip or crack.
- Very hard wearing
- Can be installed on floors and walls
- Variety of colours
- Never needs sealing
In commercial situations speciality epoxy grouts are used in hospitals, cafes, restaurant kitchens, bathrooms, pubs, cool rooms and freezers. Please remember that commercial epoxy grout is different to a domestic version. Not all epoxy grouts are the same and definitely not a “one type suits all”. We carry special commercial grout range which meets Singaporean Standards. These grouts are difficult to install and require experienced technicians and equipment. All our technicians have been trained by epoxy grout manufacturers.
In domestic applications, epoxy grout is widely used in showers, walls and floors mainly due to the fact that it is very difficult to stain, doesn’t allow mould to grow and does not get affected by chemicals found in shampoos and conditioners. Being so stain proof it doesn’t require heavy duty scrubbing or cleaning like regular grout does. It is also often used on kitchen splashbacks and floors, it repels oil stains as well as stains from general cooking.
Epoxy Grout is more difficult to install than regular grout and it does require specialists like our technicians. More labour is required and speed is very important as pot life is extremely short. Special cleaning solutions are needed in order to rinse epoxy grout residue from tiles, if the residue is not removed within a specific time frame, permanent damage can be caused. Cured epoxy grout haze is not removable.
We only install the highest quality epoxy grouts in both commercial and domestic applications. Years of experience and extensive training has enabled us to master the trade of epoxy grouting. Today’s market offers quite a few different types of epoxy grout, we do not use or recommend the ‘cheaper’ types. Our epoxy products are not cheap but they are of the highest quality available and just like with anything else, you get what you pay for.

Grouting Joint

Suggested Method Statement For Grouting Tile Joints
Grouting Joints
- Check and ensure that the tiles are soundly bonded. Clean off all loose toppings or any substances that may reduce or inhibit the adhesion of the grout to the tile joints.
- Mix the entire content of Parts A & B of QUICSEAL 613 in a clean container with a slow speed spiral mechanical mixer for approximately 2-3 minutes until a smooth homogeneous paste is achieved.
- Transfer the mix onto the working area and apply the paste with a hard rubber trowel to fill the joints completely. The working time allowable is approximately 30 minutes, depending on site condition.
- To facilitate clean-up, use the hard rubber trowel at 90° angle to remove the surplus paste from the tile surface.
- Allow the grout to settle for 10 -15 minutes before cleaning.
- Clean the surface with an abrasive sponge such as Scotch-Brite and water in a circular motion to aid cleaning.
- Rinse the sponge frequently in a clean pail of water. Do not overwork the joints as this will affect the finished appearance.
- Continue this process until all the excessive grout is removed. Make sure to remove any excess water that is left on the epoxy grout.
- Clean the installation 6 – 12hours later with denatured alcohol if stubborn haze film still remains on the tile surface
Harden grouts can only be removed by mechanical means.
Leave for at least 24 hours before allowing foot traffic.
QUICSEAL 613
QUICSEAL 613 EPDXY GROUT is a specially formulated three-component epoxy resin based product mixed with silica sand and special additives to obtain a bonding paste with extremely high adhesion strength. QUICSEAL 613 EPDXY GROUT adheres well to most surfaces and hardens rapidly without noticeable shrinkage to allow early foot trafficking. Once cured, EPDXY GROUT mortars are highly resistant to water and chemicals.
Typical Uses
QUICSEAL 613 is a chemical resistant grout and adhesive for both wall and floor applications:
• Internal and external areas; ceramic tiles, homogenous tiles, quarry tiles, agglomerates (artificial stones), natural & moisture sensitive stones, etc.
• Areas subjected to chemical contact such as dairies, breweries, food and chemical industries, swimming pools
• Areas subjected to heavy traffic such as walkways and pavements, etc.
Advantages
• Available in many colours
• Good chemical resistance
• Excellent abrasion resistance
• Excellent water resistance
• Water cleanable
Substrate Preparation
The substrates must be clean and sound, free of dust and loose particles. Laitance, oil, grease, mould release agents or curing compound must be removed from concrete surfaces by using wire brush, scabbler or other means.
Preparing the Mix
Mix QUICSEAL 613 (Part A) and Part B together in a clean pail thoroughly using a low speed mechanical paddle mixer for 3-5 minutes. Pour QUICSEAL 613 Part C into the blend and mix for approximately 3 minutes until a homogeneous paste is achieved.
Grouting Tile Joints
Apply the QUICSEAL 613 paste with a hard rubber trowel to fill the joints completely. Remove the surplus paste with a damp nylon scrub pad or sponge. Rinse the sponge with clean water. Continue this process until all excess grout have been removed. Leave for at least 24 hours before allowing foot traffic.
N.B.
Do not use QUICSEAL 613 to grout terracotta tile joints. When grouting unglazed impervious tiles or tiles of contrasting color ( i.e. beige coloured QUICSEAL 613 against white tiles ), a preliminary test is recommended. Pre-treatment of such tiles with a suitable impregnator may be necessary prior to grouting work.
Cleaning
Cleaning should begin immediately after application. All tools and hands may be cleaned with abundant water before the adhesive sets. After setting, cleaning can only be done by mechanical means.
Coverage
For grouting tile joints, consumption depends on the tile dimension and joint.
Packaging
QUICSEAL 613 is supplied in 6kg set
Storage
12 months in a cool and ventilated place in the original packaging.

Recommendations
- Because of the tessara’s reduced thickness, it can also be used for grouting glass mosaics with joints less than 3 mm.
- When grouting ceramic tiled floors and walls subject to oleic acid attack (e.g. ham and sausage industries, oil-mills, etc.) and aromatic hydrocarbon, it can be used (available in 113 or 130 reference colour).
- For flexible expansion joints or joints subject to movement use an elastic sealant.
- It does not ensure perfect adhesion when used for grouting tiles with wet edges or contaminated with cement, dust, oil, grease, etc.
- Unglazed klinker tiles should be grouted with the same colour tone. All other colours should be used only with glazed tiles.
- Do not use it for grouting terracotta tiles because they are difficult to clean.
- Make preliminary sample tests before grouting porcelain tiles with a contrasting colour (e.g. black on white).
- Always carry out preliminary tests before grouting stone or ground porcelain with a porous or rough surface.
- Do not add water or any solvents to it to make it more fluid.
- Use the product in temperatures between +12°C and +30°C.
- The quantities are already in the correct proportions, therefore mistakes should not be made. Do not guess the quantities when mixing the two components. A wrong catalysis ratio could impair the hardening process.
- When removing already cured it from the joints, use a hot air industrial drier. Remove hardened from the tiles with Pulicol 2000.
- When grouting large floor surface areas, it is recommended to use it, available in grey 113 (other colours are available upon request for quantities higher than 300 kg) because it is very fluid and easy to apply.
Application Procedure
Preparing the joints
The joints must be dry, clean, free of dust and emptied at least 2/3 of the tile thickness. The excess adhesive or mortar should be removed while still fresh.
Before grouting, make sure that the installation mortar or the adhesive has set and released most of its moisture.
It is not affected by the moisture on the surface; the joints should not be wet during work.
Preparing the mix
Pour all the hardener (component B), into a bucket containing component A and mix well until a smooth paste is obtained. For perfect mixing and avoiding overheating of the mixture, which could reduce working time, a low speed electric stirrer should be used. Use the paste within 45 minutes from mixing.
Applying the grout
Spread it with the appropriate float, making sure the joints are completely filled. Use the same float, but on edge, to remove excess grout.
Finishing
After grouting, floors and walls should be cleaned immediately, before the product dries.
Wet the surface thoroughly and emulsify with an abrasive pad for cleaning joints, making sure not to wash-out the joints. When cleaning walls, the cleaning pad should be fully soaked with water. The excess liquid can be removed with a hard cellulose sponge, and should be replaced when too full of resin. Use the same type of sponge for the final tooling of the grout. It is very important that once the finishing process has ended, no traces are left on the tile surface because it will be very difficult to remove. It is therefore necessary to frequently rinse the sponge with clean water during the cleaning process.



When finishing large floor surface areas, use a rotary, disc-type power float abrasive pads, well saturated with water. All excess liquid can be removed with a rubber squeegee. The final cleaning cycle may be carried out using special cleaning solution for epoxy grout. It may also be used to remove thin residues of grout several hours after application. In such cases, the product must be left to react for longer (15-20 mins.).
The efficiency depends on the amount of resin residues and how much time has passed since application. Cleaning must always be carried out while “fresh” as described above.
Application Procedure As An Adhesive
After mixing the two components as described above, spread the adhesive with a notched trowel. Apply the tile under firm pressure to ensure good contact. After setting, bonding becomes extremely strong and resistant to chemical agents.
Set to Light Foot Traffic
At +20°C, floors are set to light foot traffic after 24 hours.
Ready for use
4 days. Surfaces can also undergo chemical attack after 4 days.
Cleaning
Clean tools and containers with plenty of water before hardens. When it has hardened, removal is only possible by mechanical means.

Technical Characteristics
It is a two-component, epoxy resin-based product, with silica sand and other special components. It has excellent resistance to acids and is very easy to clean.
It has a bacteriostatic agent, preventing from the proliferation of bacteria and the formation of mould on the surfaces of grouts, making tiled surfaces hygienic and safe.
This is a product with very low emission of volatile organic compounds and is classified Emicode EC1 R Plus by GEV when used for grouting.
When applied correctly, it produces tile joints with the following characteristics:
- Excellent mechanical strength and resistance to chemicals, therefore excellent durability;
- Smooth and compact, surface finish which is non-absorbent and easy to clean; guarantees a high level of hygiene and blocks the formation of mildew and mould;
- High degree of hardness, excellent resistance to heavy traffic;
- No shrinkage and, therefore, no cracking;
- Uniform colour, resistant to atmospheric agents;
- Excellent workability, highly improved compared with traditional epoxy mortars thanks to its creamy consistency, which guarantees faster application times and makes it easier to clean the surfaces, with less waste and easier to obtain a good finish.
Recommendations
- Even if it already seems clean after passing over the surface with a rubber float, always clean the surface using a pad and water, to emulsify traces of resin on the surface which could otherwise modify the final surface finish.
- Use it to grout ceramic and where floor finishes will be subject to attack by oleic acids (ham curers, sausage factories, oil mills, etc.) and aromatic hydrocarbons.
- Use a flexible sealant for flexible expansion joints or for joints subject to movement.
- It does not guarantee perfect bonding if the edges of the tiles are wet or contaminated with cement, dust, oil, grease, etc. during grouting.
- Do not use it to grout terracotta tiles, the finish of the tiles may be altered.
- Always carry out preliminary tests before grouting stone or ground porcelain with a porous or rough surface.
- Do not add water or solvents to it to increase its workability.
- Use the product at temperatures between +12°C and +30°C. However, at temperatures below +15°C application may be more difficult.
- The packages are pre-dosed and, therefore, it is not possible to make mixing errors if all the contents are mixed together. Do not rough guess the quantities when mixing the two components: hardening will be compromised if the catalysing ratio is wrong.
- If hardened and it has to be removed from the joints, use an industrial hot air blower. If hardened localized residues of the product remain bonded to the tiles, use P2000 for cleaning.
Acid Resistant Grouting Application Method
Preparation of the joints
The joints must be clean, free of dust and free from adhesive to at least 2/3 of the thickness of the tiles. Any adhesive or mortar which has seeped into the joints while laying the tiles must be removed while still fresh.
Before grouting, make sure the installation mortar or adhesive has set and most of the moisture has been lost.
It is not harmed by damp from the base, but the joints must not be wet when grouting.
Preparation of the mix
Pour the catalyser into the container of part A and mix well until a smooth paste is obtained. We recommend using a low-speed electric mixer to guarantee perfect blending, and to avoid overheating of the mix which would reduce working times. Use the mix within 45 minutes of preparation.
Application
Spread it over the tiled surface with a special grout float, making sure that the joints are filled right down to the bottom. With the edge of the same float, strike off excess material.
Finish
After grouting with it, floor finishes must be cleaned while the grout is still “fresh”.
Cleaning of the joints may be carried out using a small amount of water and an abrasive sponge for cleaning joints, followed by a cellulose sponge, taking care to avoid removing grout from the joints. The sponge must be saturated with water when cleaning finishes.
The residual liquid may be removed with the same sponge, which must be replaced when it becomes too impregnated with resin, and the same technique may be used when finishing off the grouted joints.
After the finishing operation, it is very important that no traces of it remain on the surface. Once hardened, it is very difficult to remove.
Therefore, rinse the sponge often with clean water during cleaning.



In the case of very large floor surfaces, finishing may be carried out by wetting the surface and using a single-head rotary machine with special abrasive felt disks. Residual liquid may be drawn off using a rubber squeegee. Cleaner (special cleaning solution for epoxy grout) may also be used for the final cleaning cycle and may also be used to remove thin residues of grout up to several hours after application. In this case, the product must be left to react for longer (at least 15-20 minutes).
The efficiency of Cleaner depends on the amount of residual resin and how much time has passed since application.
Cleaning must always be carried out while the product is still “fresh” as described above.
Application Procedure as an Adhesive
After mixing the two components as described above, spread the adhesive with a notched trowel. Apply the tile under firm pressure to ensure good contact. After setting, bonding becomes extremely strong and resistant to chemical agents.
Set to Light Foot Traffic
Floors may be subjected to foot traffic after 12 hours at +20°C.
Ready For Use
3 days. After 3 days, the surfaces may also be subjected to chemical attack.
Cleaning
Tools and containers may be cleaned while the product is still fresh using plenty of water. Once it has set, it may only be removed mechanically.
Consumption
The consumption varies dependent on the size of the joints and the size and thickness of the tiles.
Packaging
It is supplied in pre-dosed packages. It is contained in tubs which contain component A and a canister containing component B, which must only be added at the moment it is required. The product is available in 3 kg and 10 kg containers only for the coloured versions n. 282 – 283 – 100 – 113 – 114 – 132.
Colours Available
