To make the stone of a terrace last, to last, to give a healthy and sustainable vintage look to exterior woods, everything becomes possible provided you make the right choice to protect these natural materials.
Natural and timeless, living materials, wood and stone require special care outdoors, to maintain their beautiful warm and elegant appearance.
On a facade or a terrace, in wood or stone, water is the first enemy. On wood it will lead to the destruction of its surface and on stone it will encourage the appearance of parasitic organic matter.
UV rays cause the graying of wood, which is often acclaimed today for its vintage look. But gray wood not protected from water will be damaged very quickly.
Water and wood
Water causes the wood to swell and then deflate when it evaporates. Under the effects of hygrometric variations, the wood wears out and delaminates, that is to say that it breaks up into small strips: the very structure of the wood is irreparably damaged.
Water is also one of the driving forces for nourishing all the insects and fungi that attack and invade the wood.
Water and stone
As with wood, water nourishes micro-organisms and causes the proliferation of mosses, lichens and other organic materials which pollute the surface of the stone.
With the gel, the water inside the stone, causes it to burst and weakens its surface.
The solution of Owatrol® with H4 WOOD & STONE, a water repellent but not only! 4 H - decryption:
H as a hybrid system for unique protection.
H as water repellent: wood and stone become impermeable to the water which beads on the surface without entering.
H as hydrophobic: the support is fully protected and repels water from the inside, delaying the proliferation of polluting organic materials.
H as highly compatible: H4 WOOD & STONE works with all aqueous phase finishes going on wood, transmitting all its qualities.
H4 WOOD & STONE and wood
When you want to obtain or keep the gray appearance of wood from UV rays, you must absolutely protect the wood from water. The H4 WOOD & STONE particles penetrate into the support and bring hydrophobic active ingredients which will protect the wood at its core. Indeed loaded with hydrophobic particles, the wood is deprived of water, no longer cracks, no longer delaminates and can no longer "feed" molds. The wood can then age and quietly turn gray.
H4 WOOD & STONE and stone
H4 WOOD & STONE penetrates even the most fragile stones (marble, tufa ...) and all porous mineral supports (cement, plaster, paving), to offer a repelling action of water and limit fouling as well as deposition of atmospheric pollution. The hydrophobic action also prevents the grip and the development of microorganisms which can invade the stone.
The most that makes the difference
More than just a water repellent, H4 WOOD & STONE does not contain silicone. In general, water-repellent products always incorporate silicones and deposit a film programmed to last several years. If you want to change the finish or protection, you must either wait or strip. Thanks to its composition, H4 WOOD & STONE leaves no film on the surface and does not contaminate wood or stone with silicones: it becomes easy to apply a new finish or to carry out maintenance.
Tip at home: indoors, added to 10% in a paint, H4 WOOD & STONE transmits its water-repellent qualities to the finish and provides resistance to the effects of water (ideal for a kitchen or bathroom ) and easier washability of the support.
Aging and becoming calm gray: H4 WOOD & STONE The modern solution against the effects of water for all wooden or stone substrates.
Waterproofs the support, protects it from dirt
Can be covered because without silicone
Keeps the natural surface gray while protecting the wood against moisture absorption
Colorless water repellent that permeates the support in depth and waterproofs it. Repels water and thus prevents snagging and the development of greenery and various types of soiling
Without silicone, can be covered by any type of coating without any stripping beforehand
Can be added to paints, stains and saturators in aqueous phase (approximately 10% of H4 WOOD & STONE without exceeding 20%)
Completely colorless, without anti UV, H4 WOOD & STONE allows wood to gray naturally while protecting it from moisture uptake
Helps with the self-cleaning of the support, retains its natural color. Easy support cleaning
Colorless protection for stone, including the most fragile (marble, tufa ...), H4 WOOD & STONE limits deposits of dirt and atmospheric pollution on porous mineral supports such as cement, plaster, paving ...
Also allows to protect sawn timber during transport in difficult conditions (containers, filmed pallets ...)
The pH is neutral, does not damage the support including the most fragile
All wood for chalets, cladding, terraces, garden furniture, fences ...
White stones of which the most fragile, paving, cement, plaster ...
Applies to vertical and horizontal surfaces
H4 WOOD & STONE does not in any way prevent graying of wood
