NoMorePly products tips and information.

Do I need to use MegaStrength on the NoMorePly boards?

YES.  All the main NoMorePly installation methods involve the use of MegaStrength adhesive and it is a crucial part of the installation system that shouldn't be omitted.

...or have a look at our installation videos -

We offer a lifetime guarantee based upon the results of the extensive testing performed on these products.


Which way up does NoMorePly need to be installed?

One side of the NoMorePly tends to be smoother than the other due to the manufacturing process. However, the boards are homogenous so they can be installed whichever way up you feel is suitable for the work you are doing.

How many screws are needed per board?

Please use a minimum of 8-9 screws per board, to ensure a strong, robust fitting that will minimise any board movement over time...  but don't scrimp on the MegaStrength adhesive!

How many boards will a tube of Mega Strength do?

A single tube of MegaStrength adhesive will usually cover between 4 & 6 boards. We advise using a generous amount along the edges of the boards to ensure strong bond on the joints, and to prevent the individual boards from moving in relation to each other.

Do I need to prime the boards?

Priming the NoMorePly Fibre Cement boards is always a good thing for a number of reasons:

  • It makes the boards waterproof rather than water-resistant.
  • It enhances the bond strength between the board and the adhesive.
  • It consolidates any dust on the surface of the boards.

You will need to prime both sides of the boards when using cement adhesive to fix the boards to a solid wall or floor.

NoMorePly Tilers Primer should be diluted 1 part primer & 3 parts water before use.  Using it neat will not be an advantage.

Can you paint over the boards?

NoMorePly boards can be painted if required.  A coat of primer will consolidate any dust on the surface and help the paint to adhere.  You may wish to skim plaster the boards or to tape-&-fill the joints to make the surface smooth before painting.

Are the NoMorePly boards made with Asbestos?

NoMorePly boards are definitely not made with asbestos. The use of asbestos for manufacturing was banned back in 1999.

NoMorePly boards are cement based, and certified by Resource & Environmental Consultants Ltd(REC).

Can you plaster over the boards?

Yes, it is perfectly fine to plaster over the boards.

First prime the boards both sides, install the boards on the wall according to the manufacturers' recommendations, then apply a second coat of primer, and plaster over whilst still the primer is still tacky to ensure good adhesion.

Are the boards fire rated?

The NoMorePly boards are rated Class A1 (the highest standard) for spread of flame,  meaning the boards will not catch fire or spread flame across the surface.

At this time, the boards do not have a fire rating for Fire Resistance (which includes the 30 minute burn time). This is something we are looking to test in the future.

Can the boards be used externally?

The NoMorePly boards can be used externally as long as they are fully primed on both sides first, to make them weatherproof.

Can the boards be cut using a stanley knife?

We would recommend either the NoMorePly Scoring Tool or an angle grinder to cut the boards.  You can make straight cuts with a score-&-snap tile cutter and you can use tile nippers to shape the board to fit around pipework and other such obstacles, or use a jigsaw with an appropriate blade.

A stanley knife will blunt very quickly if used persistently, and could even snap.

Can 6mm NoMorePly be used to overboard a stud partition wall?

Yes, 6mm NoMorePly can be used on a stud partition wall as long as you ensure that it is adequately supported.  There must be a support on all four sides of each board, and a support in the middle of each board.  Often this means that you will need to add a few extra noggins to your existing stud partition.

Once the partition has been adapted to suit the dimensions of the 6mm boards (1200mm x 600mm) you can proceed following the same instructions as for the 12mm boards.

The 6mm boards will hold the same weight of tiles as the 12mm boards but they have a lower ‘screw spoil strength’ so for example you would need to provide a ‘pattress’ behind the 6mm boards when fixing a towel rail to the wall.

Can I use 12mm NoMorePly on the floor instead of 6mm?

Yes, the 12mm can be used on the floor in the same way as the 6mm if you require a greater build-height in a room.  The rigidity of the 12mm NoMorePly is similar to that of the 6mm NoMorePly and it will perform in the same way.

Can I fit Karndean or similar luxury vinyl tiles on NoMorePly?

Yes, all brands of luxury vinyl tiles can be installed onto NoMorePly without any difficulty. However, the joints of the NoMorePly may show through the vinyl tiles after a while. To avoid this you can either 'feather' the edges of the NoMorePly with a cement-based screed product, or apply a self-levelling screed to the whole floor for a very smooth sub-floor.

Can I prime the NoMorePly with PVA instead of the NoMorePly Primer?

No, PVA primer will not do the job.  There are various reasons for this:

  • PVA is not waterproof -it dissolves on contact with water- so it will not make the NoMorePly waterproof.
  • PVA tends not to absorb into the board so it can peel off quite easily.  The tile adhesive then doesn't adhere to the board, but only to the weak coating of PVA.
  • It is not recommended by the adhesive manufacturers either...  Here's a useful post from one of the well-known brands:

What adhesive should be used to fit luxury vinyl tiles to NoMorePly?

Regular adhesives as specified by the supplier of the luxury vinyl tiles will work well. For confirmation or recommendation, have a look at the F.Ball test report here: 

TS12900  01 November 2016 
From: B. Johnson       To: Mr. S.A. Boulton 
Specialist Tiling Supplies (STS) 
1. Introduction 
Following contact with Steve Boulton, Mr. Eddie Burrowes, Managing Director of Specialist Tiling Supplies has supplied a sample of No More Ply (6mm), a solid cement particle board, for assessment. They have reportedly requested assessment as a base for the installation of LVT’s with F. Ball adhesives. 
2. Experimental 
The following adhesives were used to prepare ~300mm x 250mm subjective peel bonds to No More Ply, primed with dilute Stopgap P131: 
Styccobond F44 Styccobond F46 Styccobond F48 Styccobond F49 
The bonds were assessed after 7 days. 
3. Results 
Styccobond F44 - very good bond, adhesion failure to flooring Styccobond F46 - very good bond, adhesion failure to flooring Styccobond F48 - very good bond, failure tends to be between P131 and No More Ply Styccobond F49 -  very good bond, failure tends to be between P131 and No More Ply 
4. Conclusion 
All of the adhesives tested, F44, F46, F48 and F49, are suitable for use with LVT’s over the supplied 6mm No More Ply. 

Does NoMorePly contain Silica?

Silica can be found in sand, quartz, granite, cement, and stone, so if you're in the tiling trade, the chances are that you've been in contact with it many times over the years and unfortunately it's not good for you. The good news is that the amount of Silica in NoMorePly has been shown in independent tests as being low enough to be classed as 'insignificant' and therefore no cause for concern.

We'd advise you to take sensible precautionary measures when cutting NoMorePly, just as you would with the other products mentioned above.

1) Work outside if you can but don't insist on it -sometimes it's just not practical.
2) Score and snap when you're making straight cuts in NoMorePly rather than using the grinder all the time
3) Wear a mask if you need to do lots of angle-grinder cuts, dampen the board surface.
4) Stay safe, use common sense!

Can 6mm or 12mm NoMorePly be installed straight to joists?

No, 6mm and 12mm NoMorePly are not structural boards and cannot be installed straight to joists. They need to be installed on top of an existing floor to strengthen the floor, rather than replacing the floorboards. 

Our 22mm fibre cement board can be installed straight to joists and has been developed as a direct replacement for floorboards.
