Mapei Keraquick XL Fiberlite

Mapei Keraquick XL Fiberlite extended informationConsumption: 6-8m2 depending on bed depth.Mapei Keraquick XL Fibrelite is a powder composed of a mixture of special cements, selectively graded aggregates, synthetic resins, fibres and setting accelerators that develop a high bond strength only 90 minutes after setting. For this reason floor installations can be completed very quickly. Floors can be walked on after only 90 minutes and are ready for general foot traffic after 12 hours. When hardened Mapei Keraquick XL Fibrelite is frost and water resistant.Application ProcedurePreparation of the substrateSubstrates must be dry, flat, mechanically strong, sound, free from loose areas, grease, oil, paint, wax, old flooring adhesive and bitumen residues and any other contamination (e.g. plaster droppings), which may affect the adhesion. Damp substrates may lengthen the adhesive setting time. Cementitious substrates must be cured and any shrinkage process must be at an end before tiles are installed. Concrete must be at least 6 weeks old, cement based screeds for at least 3 weeks unless they have been produced using the special MAPEI binders Mapecem or Topcem or with a preblended screed mix such as Mapecem Pronto or Topcem Pronto. The substrate surface should ideally be open textured. Powerfloated concrete should be mechanically abraded (scabbled or shot-blasted) to open up the surface and to remove any curing agents. Heated screeds must be commissioned in accordance with recognised technical regulations and the guidelines given in BS 5385 parts 3, 4 and 5. The commissioning process must be carried out before the installation of tiles or stone finishes. Calcium sulphate screeds must be dry to a moisture content of 0.5% w/w when measured using the carbide method. All surface laitance must be removed by mechanical abrasion and all dust thoroughly removed by vacuum. Prime the surface with Mapei Eco Prim T Plus (diluted 1:2 with water) or alternatively Mapei Primer G (neat). Tilebacker boards must be installed to provide a firm, stable substrate with no protruding fixings. Plywood overlaid floors must use a minimum 15 mm exterior grade plywood and be fixed at minimum 300 mm centres in all directions to provide a rigid substrate. Prime with Mapei Eco Prim Grip Plus.In areas subject to extreme damp (showers etc) Mapei Mapegum WPS, Mapelastic Aquadefense or Mapeguard WP 200 should be used to waterproof the substrate. Not suitable for areas subject to flexing or vibration, or bonding tiles to metal surfaces.MixingMapei Keraquick XL Fibrelite must be mechanically mixed in a clean vessel with clean water until a smooth lump free paste is obtained. Allow the product to stand for 2-3 minutes before re-mixing. The product must be used within 40 minutes. Mapei Keraquick XL Fibrelite 15 kg should be mixed with 5.1-5.4 litres of clean water.Applying the productKeraquick XL Fibrelite is applied to the substrate with a notched trowel to a max 15 mm in thickness Adhesive coverage will be determined by the notch size chosen and should be 100% as far as possible for floors, exterior and wet areas. For tiles exceeding 300×300 mm Keraquick XL Fibrelite should also be applied to the backs of the tiles (back-buttering). For very absorbent surfaces or during hot weather the substrate should be dampened to extend the open time of the adhesive. It is not necessary to wet the tiles before fixing, however if the backs of the tiles appear dusty they should be wiped over with a wet sponge.Mapei Keraquick XL Fibrelite has an open time of 15-20 minutes in normal temperature and humidity; unfavourable weather conditions (strong sun, drying wind, high temperature), or a highly absorbent substrate will shorten this open time, sometimes to just a few minutes. Should the adhesive form a skin it should be removed and fresh adhesive applied. Tiling fixed with Mapei Keraquick XL Fibrelite must not be subjected to washout or rain for at least 60 minutes and protected from strong sun and frost for at least 12 hours.GroutingTile joints can be grouted after 2-3 hours with a suitable MAPEI cementitious grout. If the joints require better chemical resistance or where hygiene is of importance use a suitable MAPEI Epoxy. Expansion joints should be filled with MAPEI Mapesil AC or Mapesil LM.Set To Light Foot TrafficFloors are able to take light foot traffic after approximately 90 minutes.Ready For UseFloors are read for use after approximatelv 12 hours.Mapei Keraquick XL Fiberlite technical dataType:powderColour:grey or whiteDensity:1.2-1.35Viscosity:350-450Mixing ratio:- grey 36-38 - White 36-38Consistency:semi fluidPot life:40 minutesApplication temperature range:from 5°C to 30°COpen time:15-20 minutesSet to light foot traffic:90 minutesReady for use:12 hoursTensile strength: - initial 28 days: - after heat ageing: - after water immersion: - after freeze thaw: 2.00 2 1 1 Categories: Rapid Set Tile Adhesive pallet deals & bulk buy, Tile Adhesives - Pallet Deals
