Poseidon's Tile Primer

Poseidon is a water-based, ecological impregnator that creates a barrier against moisture and prepares the surface so that a penetrating sealer can bond and perform consistently. It is required as a preparation step before sealing — Poseidon must be used together with a penetrating sealer (such as Zeus' Tile Sealer) to achieve complete protection. On its own, Poseidon does not provide surface protection against staining or etching.

Poseidon is suitable for cement tile, natural stone, and other absorbent surfaces, both indoors and outdoors. For terracotta and cotto, use Demeter's Terracotta Primer instead, which is formulated specifically for those highly porous clay materials. Like Poseidon, Demeter must be followed by a penetrating sealer such as Zeus' Tile Sealer for full protection.

Make sure the surface is clean and dry; remove dust, dirt, and residues with a broom or vacuum. Shake Poseidon well, then apply evenly with a brush, roller, or low-pressure sprayer and allow it to penetrate for 10-15 minutes. Reapply while still wet on highly absorbent surfaces
until the surface no longer absorbs liquid — at that point the primer is fully saturated. Let it dry completely; allow a 24-hour cure time before proceeding to grouting or sealing.

For cement tiles, apply Poseidon BEFORE grouting to protect the tile from absorbing grout pigment and moisture. Wait 24 hours, then grout. After the grout dries, clean the surface with Athena's Heavy Duty Tile Cleaner (or another heavy-duty cleaner) to remove any grout haze or residue. Then apply Zeus' Tile Sealer following its specific instructions for optimal protection.

Poseidon is supplied in a 32 fl oz (950 mL) bottle. Actual coverage depends on tile porosity and texture; on typical cement tile installations our customers report approximately 100-160 square feet per bottle. Highly absorbent surfaces will use more product.

No. Poseidon is designed to preserve the natural appearance of the material without altering its look. As with any tile product, conduct a preliminary test on an inconspicuous area to confirm the result before treating the full surface.

Yes. Poseidon is suitable for both indoor and outdoor applications. Work in a well-ventilated area, avoid applying in adverse weather, and follow the same cure-time and water-exposure guidance as for an indoor installation.

Yes. Poseidon is a water-based, ecological impregnator formulated to be environmentally friendly while still delivering effective surface preparation and moisture resistance. Avoid release to drains or waterways during use, and dispose of product waste and the container in accordance with local regulations.

Use in a well-ventilated area. Wear protective gloves, eye protection, and face protection; use a respirator if ventilation is limited. Avoid breathing fumes, mist, vapors, or spray. Keep away from heat, hot surfaces, sparks, open flames, and other ignition sources. Wash hands and face thoroughly after handling, and always review the Safety Data Sheet (SDS) before use.

Clean all tools with rubbing alcohol immediately after use. Store Poseidon in its original sealed container in a cool, well-ventilated area away from direct sunlight, heat sources, open flames, sparks, and other ignition points.
