Any alternatives to using Mapei Nivorapid and Mapeprim SP

[bowlegs]

Evening Guys,

I'm looking to level some WBP Ply in the kitchen with some Mapai Ultraplan Renovation. In the data sheet for the product as part of the substrate prep, it specifies using "Nivorapid with Latex Plus" to seal any open joints on timber flooring then "prime with Mapeprim SP". As the joints between the sheets of ply I have laid are 3mm to allow for any expansion, are there any alternatives to using the rather expensive Nivorapid as the joints in total are around 25m in total length? Perhaps a silicone mastic? Also any thoughts on an alternative too the priming with Mapeprim.

Many thanks in anticipation.

All manufacturers will recommend using the same manufacturers products throughout because they only test their own products and not other manufacturers. So Mapei recommend using Mapeiprim, Ultraplan Renovation and Nivorapid with Latex Plus as a tried and tested solution to your problem. There are other manufacturers out there with excellent products that don't cost as much as Mapei - but Mapei products are very good quality and many trade tilers swear by them. My suggestion is that unless money (budget is tight) is a real issue - go with Mapei all the way (including tile adhesive, grout and silicone). Mapei also has an excellent technical support system - don't be shy of phoning them for advice.

Andy, thanks for your reply, I don't want to jeopardise the quality or finish of the job and although in the big sceme of things another £80 or so isn't that much I was just trying to establish if there was an alternative that would be compatible with the mapei products already purchased for the job (adhesive, grout and Ultraplan Renovation). If there are no viable alternatives then I'll go with the Nivorapid etc. Cheers.

Surprised your using plywood over the Hardiboards as the expansion issues don't arise!
