A Technical Explanation Of

Multi-Primer's Unique Features

Senseal’s Multi-Primer 'Deep Seals' any wood by displacing or sealing in the liquid content of the wood (water, oils and sap). This is achieved through features entirely unique to Senseal products, and Multi-Primer in particular:

DEEP PENETRATION – Multi-Primer contains a blend of precisely mixed organic solvents and a high alcohol content making it a unique epoxy resin with the ability to dissolve wood oils, saps and even the water content of the fungus that cause dry rot. The deep penetration by Multi-Primer along the natural moisture veins of all types of wood brings excess liquid to the surface and the evaporation of moisture that could cause rot or paint deterioration.

DEEP SEALING – Multi-Primer's core ingredients are derived from natural wood resins, rather than petrochemical products used in other epoxy resins. Multi-Primer penetrates the wood cellulose fibre structure of timber, which fungi and bacteria like to destroy. This enables cellular level bonding creating a super strong fully cured resin with similar flexibility to timber, allowing the timber to breathe while preventing water retention that causes wood to dramatically expand and rot as it dries out. The timber is now permanently protected from wet and dry rot!

STABILISES WOOD – An amazing outcome of Multi-Primer’s ‘Deep Sealing’ is that the excessive expansion or contraction of wood due to weather conditions and exposure to water is eliminated. This means Multi-Primer dramatically reduces any warping, cupping, gapping, cracking, joint and coating failure that lead to rot, and the need to replace timber or whole structures.

COATING ADHESION – Multi-Primer 'Deep Glues' any paint, varnish or stain by chemically bonding with it as it is applied, significantly increasing its life span. This is achieved by the impregnation of Multi-Primer into the timber's cellulose fibres. While Multi-Primer cures within the wood, a very thin film of wood-derived epoxy glue remains on the entire surface and continues to cure after a topcoat is applied. The curing process is designed specifically so that Multi-Primer chemically bonds with the topcoat, effectively gluing the coating into the wood. Timber not treated with Multi-Primer will tend to draw out the water content of coatings, leaving brittle remains that easily deteriorate. Other primers suffer the same problem, breaking the primers seal, and leading to coating deterioration.

CLEAR FINISH – Multi-Primer enhances the natural colour of wood because as it bonds with wood at a cellular level, the natural features of the wood, like its colour, are reflected in the cured resin and fixed in place throughout the Multi-Primer treated timber. Multi-Primer’s subtle clear amber tone has the effect of enriching the timber’s natural colour and giving Multi-Primed wood a long lasting ‘as new’ look and feel. Alternatively when one wants to maintain a rustic weathered appearance, Multi-Primer applied to old weathered wood will preserve this ‘look.’ To ensure Multi-Primer keeps protecting your wood a UV blocking stain or varnish is required outdoors.

SHELF LIFE – If Multi-Primer is stored unopened, above freezing, and is sealed correctly it should virtually last forever! Once opened, however, if sealed correctly between uses, it will easily last a year.
