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.

Surface Preparation

Concrete and Ceramic

As with all concrete repairs, it is essential to remove all grease, oil, dust and other loose materials. Concrete substrates must be adequately prepared either by use of a suitable mechanical method such as scrabbling, grit blasting or needle gunning.

Steel

Degrease steelwork if neccessary. Remove dust and debris. Ensure surfaces are dry and prime with QUICSEAL EPOXY PRIMER working well into the surfaces. Allow to dry for 30 minutes before firmly applying QUICSEAL 301.

A smooth surface maybe obtained with a damp or heated trowel.

QUICSEAL EPOXY PRIMER may be applied to dry or slightly damp, but not wet surfaces.

When applying QUICSEAL 301 to damp surfaces, one must work the epoxy mortars thoroughly into the wet surfaces to obtain complete surface adhesion.

QUICSEAL 301 should not be applied more than 20 mm thick in one application on vertical surfaces to prevent slumping.

Site Instructions

Mechanically clean concrete and steelwork to remove loose, weak and ontaminated surfaces and dust, scale, etc. Degrease steelwork if neccessary. Remove dust and debris. Ensure surfaces are dry and prime with QUICSEAL EPOXY PRIMER working into surface. Allow to dry for 30 minutes before firmly applying QICSEAL EPOXY MORTAR. A smooth surface may be obtained with a damp or heated trowel. QUICSEAL EPOXY PRIMER may be applied to dry or slightly damp, but not wet surfaces. QUICSEAL EPOXY MORTAR may be used on wet surfaces but must thoroughly worked into the wet surface to obtain complete surface protection and adhesion.

QUICSEAL EPOXY MORTAR should not be applied more than 20 mm thick in one application on vehicle surfaces, to prevent slumping. In most cases, where concrete surface is rough, no primer is required.

Underwater APplication – QUICSEAL EPOXY MORTAR

Surfaces must be mechanically cleaned, free of weak or loose material, marine growth, rust, scale, etc. Mixed QUICSEAL 301 should be carried in plastic bags to work area in small quantities, approximately 5 mm thick, pressed, pressed into position ensuring that all water is expelled from between the repair surface and the QUICSEAL 301. Mixed mortar should be applied within 30 minutes of mixing. COntact between the mixed mortar and water should be avoided until the point of application. Uncured material should be protected from scouring and displacement by moving water until cured.

Mixing and Storage

Store the materials away from sunlight or heat before using, as heat will shorten pot-life of materials. Mix materials in the ratio of 3:1 by weight (Part A:Part B) until a homogenous colour is obtained (1 to 3 mins). For large quantities, mechanical mixer should be used, for small quantity, it can be hand mixed.

Packing

3 kg and 12 kg set

Storage

The shelf life of QUICSEAL 301 is 12 months when stored unopened in a cool and dry place.

Health & Safety

Gloves and goggles should be worn. Any splashed to the skin or eyes should be washed off with clean water. In the event of prolonged irritation, seek medical advice. Powder products should be handled to minimize dust formation. Use a light mask if axcessive dusting is unavoidable.

QUICSEAL 302LV Epoxy Injection Resin

QUICSEAL 302LV Epoxy Injection Resin is a two-component, solvent-free, low viscosity epoxy resin specially designed to repair cracks in concrete. It is moisture tolerant, allowing for injection into damp cracks and provides good water resistance and protection against chemical attack.

Uses

  • injection sealing of hairline cracks in concrete structures and masonry
  • rebonding and cavity filling of hollow walls and floors
  • grouting machinery base when combined with clear dry silica sand
  • virtually impermeable to carbon dioxide and protects the concrete against carbonation

Advantages

  • Fast cure – Short downtime
  • Non Shrink – negligible volume shrinkage after cure
  • Low viscosity – Allows penetration to very fine gaps
  • Adheres to damp surfaces – Allows injection into damp cracks

Instruction for Use

QUICSEAL 302LV Epoxy Injection Resin is particularly useful as a method of carrying out structural repairs of concrete and masonry. It forms a bond between the broken sections stronger than the materials itself and seals the cracks the cracks against ingress of water and other aggressive agents which may have a deleterious effect on reinforcement.

Before deciding to inject cracks, the cause of the cracks must be established and ensure that they are not still moving by using suitable tell tale devices. If movement is occurring, the crack should be treated as a normal movement joint. Otherwise, the crack and surrounding surface must be thoroughly clean, dry and all loose debris removed.

QUICSEAL 304 EPOXY PUTTY is then used to the surface and bond on the injection nipples will be approximately 1 ½ – 2 times (less for very fine cracks) the thickness of the concrete member to be repaired. Cracks through the entire thickness of the concrete member should be sealed on both sides. Once QUICSEAL 304 EPOXY PUTTY has hardened, which normally takes about an hour, the injection resin is mixing by using slow-speed drill and paddle for about 1-3 minutes until a homogenous honey coloured liquid is achieved. Simply inject the mixed resin into the horizontal or vertical cracks.

Note

The gel time of premixed material is dependent on the quantity of the batch and temperature. A large batch is likely to react much faster than a small quantity of material. Therefore it is crucial the user of single component equipment to monitor closely to prevent premature reaction in the pump system. If a reaction of the batch occurs while pumping, immediately shut down the machine and flush with a cleaner to avoid built up and clogging of the equipment.

Coverage

1 litre will fill a length of 13m for a cavity of 25mm deep by 3mm wide.

Cleaning of Tools

Tools and equipment may be cleaned with xylene or aromatic solvents

Packing

QUICSEAL 302LV Epoxy Injection Resin is supplied pre-weighed in 1.5kg & 6kg set.

Precaution

  • as with all EPOXY RESIN products, wear protective overalls and gloves- prolonged contact with the skin should be avoided.
  • ensure adequate ventilation
  • skin contamination should be cleaned immediately with soap and plenty of water. If resin or hardener enters the eyes, wash immediately with running water and consult a doctor immediately
