Application
Coverage

MIXING
Employ all appropriate safety equipment before use. Refer to the Safety Data Sheet for details.
SikaTile®-825 Epoxy Grout parts A (2 lbs.), B (1 lbs.) and C (10 lbs.) are packaged to ratios for proper curing. Stir then pour all material from the Part A containers into the mixing bucket then repeat using Part B. To ensure product performs to specifications empty out all contents of Part A and Part B by using a margin trowel to thoroughly scrape all material from the containers. Add all of Part C colored powder. Always mix complete units and do not add any other materials to this mixture. Use a slow-speed mixer (at 300 rpm), or manually mix with a margin trowel. Avoid prolonged mixing, which will trap air and shorten the pot life. Mix thoroughly until a homogenous, consistent color is obtained with a thick peanut butter like consistency. Scrape the edges of the mixing container at least once during mixing. Wash tools immediately with water before the epoxy hardens. Do not place the lid on the container after the material has been mixed.
APPLICATION
Read all installation instructions before installation.
For use as a grout:
Remove mixed SikaTile®-825 Epoxy Grout product from the container and place it in small piles (if grouting a wall, place the product on kraft paper laid on the floor). Use an epoxy grout float with a sharp edge to force the grout into the joints in a continuous manner, leaving it flush with the tile edge and be sure that all joints are well-compacted and free of voids or gaps. Thoroughly remove excess grout from the face of the tile before it loses its plasticity or begins to set by holding the rubber float at a 90-degree angle to the tile surface and dragging the float across the tile surface diagonally to the grout lines. Clean tiles immediately after applying each unit of SikaTile®-825 Epoxy Grout by applying a liberal amount of cold water to the freshly grouted area. Scrub the tile surface diagonally to the joint line using a white nylon scouring pad. Apply enough pressure on the pad to loosen any film without removing grout from the joints. Rinse pads frequently while cleaning. To remove the loosened epoxy residue and water, drag a clean sponge diagonally across the tile surface. Use one side of the sponge for each pass over the tile, rinsing the sponge following the second pass and regularly changing water in the buckets to avoid residue buildup. Do not allow SikaTile®-825 Epoxy Grout to harden on the tile surface. Do not step on freshly cleaned tiles, as this could permanently damage the grout.
For use as a mortar:
Remove the mixed SikaTile®-825 Epoxy Grout product from the container and place it in piles on the floor. Choose a notched trowel with sufficient depth to achieve more than 80% mortar contact to both the tile and substrate for all interior applications, and more than 95% for exterior, commercial floor and wet applications. It may be necessary to back-butter the tile to meet these requirements. With pressure, apply a coat of mortar by using the flat side of the trowel to key the mortar into the substrate. With the notched side of the trowel, apply additional mortar by combing it in a single direction parallel to the shortest dimension of the tile. Spread only as much mortar as can be tiled before the product skins over. Open time can vary with jobsite conditions. Set tiles firmly into the wet mortar and push the tiles back and forth in a direction perpendicular to trowel lines to collapse the mortar ridges and to help achieve maximum coverage.
FINAL CLEAN UP:
After 24 hours, the grout installation can be cleaned with clean water. Cleaning with acid is not recommended.
MOVEMENT JOINTS:
All expansion, control, construction, cold, saw-cut, isolation, contraction, and seismic joints in the structure should continue through the tilework, including such joints at vertical surfaces, as specified per TCNA Method EJ171 or TTMAC Specification Guide 09 30 00, Detail 301MJ.
PROTECTION:
Do not disturb grout or walk over installed tiles for at least 24 hours after setting. Do not allow any activity in the area that will cause dirt or debris to become embedded in the grout joints as they are curing. Do not allow heavy traffic over installed tiles for at least 48 hours after setting. For residential showers and tub surrounds, restrict use for 10 days after grouting before water immersion or exposure to chemicals. For steam showers, restrict use for 14 days after grouting.
MAINTENANCE:
Sealing is not required. Grout must be fully cured for 3 days before regular cleaning. To maintain a clean tile surface, use a neutral-pH cleaner for maintaining the floor, followed by a clean-water rinse. Do not use harsh chemical cleaners to maintain the tile surface. Before proceeding with cleaning, consult the cleaner’s manufacturer for compatibility, use, and application instructions. Remove or rinse fatty acid residue from the grout surface to avoid potential grout deterioration caused by prolonged exposure.
CLEANING OF TOOLS
Clean tools and tile with water before the material dries.
FAQ
SikaTile®-825 Epoxy Grout is a 100-percent-solids epoxy grout and mortar that should be used for moisture-sensitive material.
SikaTile®-825 Epoxy Grout is a 100-percent-solids epoxy grout and mortar that bonds securely to mesh- or resin-backed tile.
For unsightly efflorescence to be present you must have three things: water, water-soluble minerals, and a pathway such as capillaries for the moisture to escape and leave behind the minerals. To avoid efflorescence, you need to eliminate at least one of those three components. Several SikaTile® grouts are formulated to avoid efflorescence.
SikaTile®-825 Epoxy Grout is a 100-percent-solids epoxy grout and mortar that should be used for moisture-sensitive material.
When the grout has cured to the point where it will not transfer onto a finger applied to the joint, cleanup may begin. Grout must be fully cured for 21 days before regular cleaning.
Not all grouts require a sealer. Ready-to-use and epoxy grouts need no sealing. It is Sika's recommendation to use compatible sealer on cementitious grouts.
