Micro Milling Premium 3600 Thin Set (Available in White & Grey)- Premium 3600 thin set is a blend of Portland cement, graded sand and special additives including re-dispersible polymers which are designed to improve adhesion and provide greater bond strength.
Preferred Choice by Contractors, Tilers, Tradesmen, and Clients - Premium 3600

Features

High performance bond- best for installing tile (including porcelain) over difficult substrates.
Specially formulated for warm weather conditions
Polymer Modified
Superior flexibility and bond strength
Resistant to shock & impact
Exceeds ANSI A118.4
Mix with water only.

Uses

Suitable for installing porcelain tiles, ceramic tiles, clay tiles, concrete tiles, glass tiles, quarry tiles, brick pavers, marble and natural stone.
Commercial or Residential Installations.
Interior and exterior, floors and walls.

SUITABLE SUBSTRATES

Fully cured concrete (28 days).
Exterior Grade Plywood (Interior only)
Well prepared and bonded unglazed tile (Interior only)- For tile over tile applications, loose or fractured tiles should be removed and voids filled with an appropriate floor levelling agent or filler. Tiles should be thoroughly cleaned to remove all grease, soap scum, wax, sealers, etc. Lightly sanding the surface of the existing tiled floor will greatly improve the mechanical bond of Micro Milling Premium 3600.
Well prepared Terrazzo (Interior only)- Tile over terrazzo applications are only suitable in dry conditions. Terrazzo should be thoroughly cleaned to remove all grease, soap scum, wax, sealers, etc. Etching the surface of the terrazzo will greatly improve the mechanical bond of Micro Milling Premium 3600.

PREPARATION

Surfaces to be tiled should be dry, free of dirt, dust or curing compounds and other loose or weak material that could affect a mechanical bond. Where possible substrates should be hosed or pressure-washed.

Substrates should be even to optimise the coverage of Micro Milling Premium 3600.

mixing

Micro Milling Premium 3600 thin set should be added to clean, cool, potable water at the rate of approximately 4.6- 5.0 litres (4.9- 5.3 US Quarts) per 22.68 kg (50 lb.) bag. Mix thoroughly until smooth and let mortar slake for 5 minutes, then remix. If a mechanical mixer is used it must be done at low RPM (300 or less) to avoid entrapping air into the mortar.

Do not add water or additional powder after the slaking period. The proper mortar consistency is such that when applied with a notched trowel to the substrate, the ridges formed in the mortar will not flow or slump. Do not use mortar after initial set in the mixing bucket. During use, remix mortar occasionally.

Please note: Do not use warm water, it will accelerate the drying time of the mortar and could negatively affect the final shear bond strength.

Once Premium 3600 thin set is properly mixed never be tempted to add additional water.

APPLICATION

Apply mortar liberally with the flat side of the trowel using sufficient pressure to work mortar into good contact with the substrate. Use a proper sized notched trowel to ensure 100% coverage of mortar under tiles.

Place tiles while surface is still wet and tacky. Spread only as much mortar as can be covered in 5-10 minutes or before surface dries. Place the tiles firmly into the wet mortar. Push the tiles back and forth in a direction perpendicular to the trowel lines to collapse the mortar ridges and help achieve maximum coverage.

A ¼” gap shall be left around all vertical surfaces to allow for structural movement. Industry standards require approximately 3/32” to ⅛” (2-3mm) mortar bed thickness after tapping in. Follow ANSI A108.5 specifications for installation.

Clean excess mortar from joints so that ⅔ of the tile’s depth is available for grouting, Normal grouting can be done 24 hours after installation.

curing

Minimum cure is reached in 24 hours. Heavy traffic should be restricted for 7 days. Setting and drying times may vary according to atmospheric conditions.

coverage

This will vary according to the thickness of the tile bed required but using a ¼”x¼” (6x6 mm) notched trowel on an evenly prepared surface, a 22.68 kg/ 50 lb. bag will cover 30-50 sq. ft. (2.78-4.65 m²). Substrates that are not even or true will result in reduced coverage.

clean up

Clean hands and tools with warm soapy water before materials dry.

expansion and control joints

Provide for expansion and control joints as specified per TCNA Detail EJ171.

storage and shelf life

Store in dry conditions, off the ground in well ventilated areas for the best life expectancy- up to six (6) months from the date of manufacture in unopened containers.

safety information

Corrosive. During mixing or application avoid contact with eyes and skin. In case of contact with eyes rinse repeatedly with water and call physician. Wash thoroughly after handling. May be harmful if swallowed.

Contains free silica. Do not breathe dust. Prolonged/repeated breathing of dust may cause delayed lung injury (silicosis). Follow OSHA safety and health standards for crystalline silica (quartz).
