King® Xypex high'n dry

1 kg (2,2 lb) yields 1.25 m² (13 ft²) approximately.

Concrete must be fully cured (approximately 28 days) and dry before painting. Refer to paint manufacturer directions for application instructions.

For concrete structures that hold water (ponds, swimming pools, etc.) keep damp for 3 days, then allow to set (air cure) for 12 days. Flush thoroughly before filling. In hot weather above +21 °C (70 °F) care must be taken to prevent the coating from drying too quickly. Dampen the coating more frequently during the curing process than would be required under normal conditions.

The presence of moisture is most important to produce the crystalline growth within the concrete and proper hardening of the coating. Allow KING Xypex high’n dry to set until the surface is hard to the touch approximately 1–2 hours. The treatment must be kept damp for 48 hours following application. Under normal conditions, it is sufficient to fog spray the coating 3 times a day for a minimum of 2 days. This also prevents the chalking or dusting of the coating.

After mixing, apply KING Xypex high’n dry to the prepared surface with a semi-stiff, thick bristle brush. Always dip the brush to the bottom of the mixing pail, mixing as you obtain more material to ensure that the solids do not settle. If the mixture thickens, simply re-agitate, do not add more water. In cases of strong hydrostatic pressure, it may be necessary to apply more than one coat.

Mix 5 parts of KING Xypex high’n dry with 2 parts of clean water until a creamy consistency is obtained; avoid a “soupy” mix. Mix only as much as can be applied within 10 minutes. Use immediately after mixing. If mix starts to set, agitate briefly but do not add more water.

Surfaces to be coated must be structurally sound and clean. Remove all delaminated or unsound concrete by chipping with a hammer and chisel or using a stiff wire brush. Clean the surface of dirt, grime, mould, or any other substance that would prevent the penetration of the crystalline growth. Remove all paint. Smooth concrete must be lightly roughened or etched. Repair all cracks and holes with SAKRETE plug-tite. Clean the area with potable water, leaving the concrete saturated but free of standing water. Some very porous concretes may require several applications of water to ensure complete saturation.

Mix and substrate temperatures should be maintained between 5 °C and 30 °C (40 °F and 86 °F) for at least 24 hours prior to and 48 hours after.
