Hi. I am looking to use Sikafloor 156 as a primer/bonding bridge, prior to using self leaving compound as the self leveller on its own isn’t bonding to the vinyl floor tiles. I have old asbestos vinyl floor tiles, will sikafloor 156 bond? These vinyls tiles are smooth-ish and I’m unable to make a textured surface to ‘grip’ due to asbestos containing & too expensive to remove. My two rooms in total are about 30m2, will two 10kg sikafloor 156 be enough for bonding bridge/primer? If I’ve read the data sheet correctly, is it 0.3kg-0.5kg per m2, per 10kg sikafloor 156 or is it two sikafloor156 as it states 1-2x. Slightly confused with the consumption calculations. Please advise on how many sika155 I’d need. Many thanks for the advice.

Answer from Rawlins’ Technical Team: 

When applying Sika/SCHÖNOX levelling compounds/underlayments onto non porous substrates, it is recommended to use Sikafloor 02 Primer / SCHÖNOX SHP.

Be very careful with the prep of the tiles, abrasion techniques would not be recommended due to them containing asbestos. Please ensure they are clean and dry and free of contamination.

When used as a dpm over a new concrete floor due to a higher level of moisture in the concrete than thats exceptable. what would the m2 be?

Answer from Rawlins’ Technical Team: 

In regards to using Sikafloor 156 as a DPM Sika recommend a consumption rate of 0.5kg/m², this can either be applied in one coat at 0.5kg/m² or two coats at 0.25kg/m²/per coat.

Sikafloor 156 can go onto substrates with a moisture content of <6% (99% R/H), you can download the product data sheets from the 'Download' section on the product page.

Can I use Sika 156 primer on an old stone tiled floor with some damp, prior to laying sheet vinyl?

Answer from Rawlins’ Technical Team: 

If the moisture content is less that 99% R/H then theoretically yes. We would recommend that you remove the tiles and apply the DPM to the original substrate, this will ensure an even 0.5kg/m² of Sikafloor 156 can be applied. This may be hard to achieve if the tiles are left due to the grout lines, etc.

Will Sikafloor 156 bond to old stone tiles? more than likely, we would recommend that you abrade the tiles leaving a rough gripping surface profile.
