What is LATICRETE^® 226 and LATICRETE^® 3642?

LATICRETE^® 226 is a factory made cement, sand and polymer premix which is used to produce high strength screed /mortar mixed with LATICRETE^® 3642, diluted with water.

Where can I use this product combination?

For 12mm to 25mm thickness of screed, the total liquid required is 5 Litres where the dilution is 1:3 (LATICRETE^® 3642 : Water)

For 35mm to 50mm thickness of screed, the total liquid required is 5 Litres where the dilution is 1:5 (LATICRETE^® 3642: Water)

Can I use this product as plaster?

Yes. One can make a polymer plaster using these combination products which acts as the strong base for installation of large format tiles and stones using MYK LATICRETE polymer modified / fortified thin set adhesives.

What is the advantage of LATICRETE^® 226+LATICRETE^® 3642 screed over normal cement screed?

The cement based screed would require water curing for a minimum period of 11 days for gaining complete strength. The screed made with LATICRETE^® 226 mixed with LATICRETE^® 3642, doesn't require water curing and has better workability, compaction and finish. This is part of MBS system due to this distinct advantage. It is a great advantage when high absorbent natural stones are being installed on floors; there is absolutely no moisture present when the underlay is made with LATICRETE^® 226 + LATICRETE^® 3642.

What is MBS system? How does LATICRETE^® 226+LATICRETE^® 3642 help in this regard?

MBS system is Moisture Barrier System which is the proprietary system from MYK LATICRETE India. This is especially for Natural stones which develop stains due to their porosity and absorption of liquids. LATICRETE^® 226 + LATICRETE^® 3642 screed does not require water curing which makes the screed dry without moisture and hence natural stones are not stained due to screed moisture.

Should I apply a bond coat (Primer coat ) before laying polymer screed made with LATICRETE^® 226+LATICRETE^® 3642

Yes. Bond coat can be made by mixing LATICRETE^® 3642 with water. Alternatively LATICRETE^® 226 can be used in slurry form mixed with LATICRETE^® 3642 diluted with water in the ratio of 1:4.

What is the maximum thickness of bonded screed when made with LATICRETE^® 226 mixed with LATICRETE^® 3642?

One can make a bonded screed up to 50 mm with LATICRETE^® 226 + LATICRETE^® 3642 with ease.

What are the precautions that need to be taken before laying the screed made with LATICRETE^® 226 mixed with LATICRETE^® 3642?

The precautions before laying the LATICRETE^® 226 + LATICRETE^® 3642 screed are:

Use good quality water to mix the screed
Ensure concrete surface is cleaned of debris, curing compounds, dust or any other contaminants.
Pre-wet the concrete surface to ensure surface saturated dry conditions (SSD condition)
Key coat (priming coat) should be done using LATASCREED^® 100 / cement screed mixed with water to form slurry ensuring minimum 1 Kg consumption per square meter area of floor.
Mix the screed materials using LATICRETE^® 226 + LATICRETE^® 3642 + water, uniformly without any lumps. Check the consistency of screed.
Place the mixed materials of screed made with LATICRETE^® 226 + LATICRETE^® 3642 when the key coat is still tacky.

When can I do tiling after laying screed with LATICRETE^® 226 + LATICRETE^® 3642?

Tiles can be laid in the traditional methodology (Wet on Wet system) using MYK LATICRETE Super Set Slurry. One can also wait for 3 days after laying the screed to install tiles/stones using adhesive. Both the methods offer great advantage over normal cement screed which results in very well bonded tiles/stones without hollow sounds and chipping or popping of tiles/stones.
