About Epoxy and This Product Epoxy grout is a type of grout commonly used in tile and stone installation. Unlike traditional cement-based grout, epoxy grout is made from epoxy resins and hardeners. This composition gives epoxy grout several distinct properties, such as waterproof, stain, crack and chemical resistance, no efflorescence, much better bonding, compressive and tensile strength, etc.Its growing usage is also due to the facts of more large format tiles being installed and narrower joint width becoming more popular. Less volume of grout per site balances the concern of its high material cost (almost 4 times to the cement grout).The main benefit of this product is to complete the grouting with epoxy much more easily, no mixing or stirring needed, no worry of too much or too little liquid added causing color inconsistency, no more that sort of physical labor to float the grout into the joints, no more 2-3 times of water and sponge washing, no haze cleaning, no extra sealing needed, much less maintenance required after the installation.Due to this product's special design and different installation way, please thoroughly read the following instructions before you make the purchase. Test in a small area first to check the color and try the installation steps, before applying on the whole project. 1. Ready the site 1.1 Clean the site Make the site clean, dry, even, free of debris.Dry site matters. Wet or damp site would affect product's performance. It is another difference from water cleanable grout.Better to vacuum the joints. Too much dust left inside would affect the bonding. 1.2 Apply the wax Spread the cleaning paste (works as anti-bonding wax) lightly OVER the tile joint surface. Do not spread inside the joints.It facilitates the clean up of the cured grout excess a lot.It is a must for any rough, texture, abrasive, unglazed, or not smooth surface tile. or Use the masking tape Able to peel off just after shaping the grout. Need not wait for the curing to remove the epoxy excess.Peel slowly to avoid to take out the grout from the joints. or No wax and tape Only advised on glazed and even edge tile or stone. 2. Ready the cartridge 2.1 The seal and nozzle Keep the cap if to reseal for a next time usage. Store erectly.For 1/16" or 1/8" wide joint, the default 3/32" nozzle outlet is good to go. Just make sure no burr at the outlet.Cut or flatten the outlet if needed. Advise a vertical cut. 2.2 Load the cartridge Lock the cartridge neck in position to fix well.The nozzle inlet ID is 27 mm, different from other 21 mm. 2.3 Discard the 1st pump Get rid of the initial 4 inch material, of which the two components are regarded not mixed evenly, and thus not advised to grout the joint.Visually check the mixing state in the nozzle. 2.4 Pressure release To stop the material flowing out, press the pressure release button.To pull back or push forward the rods, also press this button. 3. Do the grouting 3.1 Dispense the grout Dispense slowly to make the joints fully packed and the material count.If material touches skin, use wet or alcohol wipe to clean. 3.2 Shape the joints Use the gadgets to shape the grout after finishing each cartridge, which normally takes about 10 minutes.The trick for shaping is to divide the excess from the grout inside the joints. It eases the residue removal after it cures. 3.3 Clean the shaper Use tissue or rag to clean the shaper after each press.If any voids spotted, use the material on the rag to refill.After shaping, leave the site as is for itself to cure. DO NOT use water or sponge to wash. It would cause mess. 3.4 Scrape the excess Scrape the cured excess and the job is done.It's able to scrape in 4 hrs at 77°F. Advise to scrape the next day.Colder weather, longer time to set. Hotter, sooner.Finger touch the excess to feel the set. How Many Units for the Project? Coverage Data is without considering the material loss. Brick Bond, 50% Offset Say the tile is 12"×24", then the joint length to be grouted for this floor or wall is 84 ft. Suppose the joint size is 1/16" width × 1/8" depth, then 1 unit is enough. Transverse line: 2'×4×7=56 ft Vertical line: 1'×4×7=28 ft Square Grid Say the tile is 12"×12", then the joint length to be grouted for this plane is 40 ft. Suppose the joint size is 1/8" width × 1/8" depth, then 1 unit is also enough. Transverse line: 1'×5×4=20 ft Vertical line: 1'×5×4=20 ft Before You Buy The correct caulking gun and gadgets are needed to apply.This product is not for grouting small size tiles such as mosaic or subway. Too many lines.It is not water-cleanable. DO NOT use water or sponge to wash the excess.It is unsanded but with superior crack resistant and bonding strength.It is a little glossy, not matt.It takes time (4 hrs at 77°F) to set initially to start scraping the epoxy excess. It might be a drawback for a contractor if he originally does not have to return to the jobsite.Due to the epoxy's intrinsic character, bright white color may yellow a bit after long time exposure to UV. This might be a concern for the exterior application of this color.A new cartridge has to use a new mixing nozzle. Applicable in Cold Weather In cold weather (below 41°F), the epoxy may become viscous and difficult to dispense out.Heat the cartridge with head down in hot water (140°F) for 20 minutes. This helps the grout flow.Use a heating bag if hot water is not available, which is helpful for frequent usages. Search B0DBLHZVZM as its ASIN.
