Larsen Concentrated Algicide is a clear liquid chemical algaecide and fungicide. It is used to eradicate algae, lichen and moulds from roofs, paths and patios prior to sealing or painting. Larsen Concentrated Algicide leaves a residual active film on the surface helping to prevent re-infection making it ideal for use as a fungicidal wall soloution during rennovation works.
Prevents immediate re-infection
Economical to use
Ideal for use on render, concrete, masonry, bitmac, paths and patios
Larsen Dustproofer is a silicate-based surface hardening liquid for concrete floors, floor screeds and renders. Larsen Dustproofer reacts chemically with cement-based substrates to form a microcrystalline seal in the surface pores of the concrete or screed. This produces a hard dust-free finish, which becomes a permanent integral part of the surface, unlike resin based sealers, which slowly degrade on concrete surfaces. It can be used on both new and old concrete floors, floor screeds, etc.
Larsen Mortar Plasticiser is a plasticising/air-entraining admixture for site-mixed bricklaying and plastering mortars.
It is manufactured from a blend of specially selected synthetic surfactants. Mortar Plasticiser improves the workability of mortar for masonry, brickwork and sand/cement rendering without the need for lime. In addition, increases the resistance of the mortar to frost by entraining air.
