Cementbased, self-levelling, hardly tension-free,pumpable, plastic and fibre reinforced.

Main Considerations for your wet room

Main issuesto considerDrainage:Decide on Drain(a) Square - Middle of floor (b) Linear - Against the wallEnsure they are approved fora wet room environment andthat there is enough depth inyour floor to install the drain.What area do you want toscreed and waterproof?(a) Shower Area(b) Bath/Sink Area(c) Whole bathroom

close pores and bind duston absorbent sub floors.LIP Primer 54 diluted withwater in the ratio of 1:1 whenused on concrete binding.On non absorbent floors,diluted with the ratio of1:1/2.Primer must be dry (approx1 hour) before the screed isapplied.

Floor Profile(a) Level floors in the wholebathroom with slope to drain.(b) Step up into the showerarea.

Why use LIPProductsIt allows you to create anyshape or size wet roombecause you are notrestricted to shower tray sizes.You can choose the styleand position of your wetroom drain.

The membrane is flexibleand designed to move withyour building.It allows you to tank thewalls and floors.LIP are water basedproducts and easy to apply. LIP works on cement basedand wooden products.

Preparation of roomDrain to be positioned intothe floor at the correct heightand plumbed in.First fix pipe work andelectrics to be in place.

Walls must be clean andready for tiling.Room must be free fromdust.NB: If you require levelaccess you may have tolower your shower area /bathroom floor. On wooden floors whereboarding has been removed,the gaps in between thejoists must be in filled withsuitable strong and stablematerial to support thescreed and tanking.

All surfaces must be free of dust, dirt,oil, grease and other separating fluids.

Priming is always required beforelevelling.

Creation of SlopesLIP 226 is cement based,retains slope and selflevelling, hardly tension-free,pumpable plastic and fibrereinforced. 2 mm – anythickness in one installation.

UseTo create slopes and levelfloors on concrete screed,wooden floors, ceramic tilesor natural stone. Suitable forunder floor heating. From2 mm to any thicknessrequired in one operation.

Creating a slopeIt is our advice to have a1.5% gradient of slope withinyour shower area to yourwet room drain. Ensure thatthe slope is sufficient for thewet room drain and area.

Tip: Baton off shower areaand create the slope to thedrain first.

Mix LIP 226 with app. 3.8 ltrof clean cold water and stirvigorously.Create slope to drain,ensuring that you follow thedrain manufactures guide

lines. Once slope hasharden, remove the batonsand pour the remainingscreed to the flooring ifrequired as a self levellingcompound ratio 4.5-5 litresper 25 kgs of water and stirvigorously to a smooth, freeflowing mortar. It is importantto pour the remaining screedwithin 2-4 hours.

Remember: If you wish toapply screed to the showerarea only and require levelaccess, the floor within thisarea must be lowered as partof your room preparation.

Preparation Time at 18-20degrees is approx 30mins.Allow approx 2-4 hours toelapse before walking /tiling. The screed must beleft to dry for 24hours priorto tanking. The floor must beprevented from drying outtoo quickly. Any repairs mustbe carried out as soon asthe floor can be walked. Ifthe repairs are left until thefollowing day, the surfacemust be primed with LIP 54ratio 1:3 prior to refilling.Note: To allow the layer ofcompound to dry slowly

Priming –LIP Primer 54The floor must be strong firmand free of dust, dirt, oil,grease, wax or otherseparating fluids. Priming isalways required, werecommend the following:LIP Primer 54 diluted withwater in the ratio of 1:3 to

Waterproofing /TankingTip: Remember areas thatyou have not tanked will notbe waterproof!!The room must be clean, dryand dust free.LIP VS 30 can be applied toany cement based productor plywood.

PrimingLIP Primer 54 is usedundiluted on organic materialssuch as Wood. Dilute LIP 54to the ratio 1:10 with water oninorganic materials such asplasterboard or screed.Apply the primer with abrush to all areas wheretanking is to be applied.

Fixing LIPReinforcementMaterialReinforcement tape willprovide additional strengthand stretch for yourwaterproofing membrane.Paint LIP VS 30 onto thesurface to fix the tape.Apply over all major joints.

Reinforcement is fixed with LIP VS 30. Depending on the type of drainagemake sure that all sides arereinforced.

After sealing all joints, corners, pipesect. the room is ready for priming.

All walls and floor must be primedbefore tanking.

Tanking with LIP VS 30 is easy.2 layers must be apllied to achieve athickness of 1 mm.

Make sure to have an on-goingworking process.

When making a slope make sure thatthe compound does not run into thedrain.

Waterproofing

protect from draughts, highroom temperature, directsunlight etc.LIP 226 should not be usedout doors and must be coveredby a waterproof membranewhen in damp rooms.Store in a dry place andprepare at temperaturesabove 5 degrees.

In the wall corners.Where the floor and wallsmeet.Around pipes and electricsWhere the drain and thefloor meet.

WaterproofingWhen the priming is touchdry approx 30 mins. A 1 mmthick layer of LIP VS 30 isapplied using a roller. Use abrush to apply themembrane in the cornersand around any difficult area.

Apply 2 coats of LIP VS 30to achieve a 1 mm coat.The room can be tiled afterthe waterproofing membraneis fully dry approx 12- 24 hrs.We suggest the use of LIPFlexible Tile adhesive foryour tiling.

It is very important that the areaaround the pipes is 100% waterproofas water might run backwards alongthe pipe into the wall.
