ACS Boracol 10 - Boron Woodworm & Rot Treatment

Protection of Bats

All bats are protected under The Wildlife and Countryside Act 1981. Before treating any structure used by bats, consult English Nature, Scottish National Heritage, The Countryside Council for Wales or The Department of the Environment for Northern Ireland.

Preparation - Beetle Infestations

Ensure that all timbers to be treated adequately exposed and cleaned, (vacuum cleaning preferred). Any paint or varnish finishes or any severely damaged sapwood edges of timbers (‘frass’) should be removed prior to treatment where possible.

Remove thermal insulation in roof spaces (or roll up and completely cover) and do not reinstate until timbers are dry.

Cover fitted insulation (lagging on pipes) with polythene and cover water storage tanks with heavy grade polythene to be left in-situ after treatment.

Isolate electrical circuits in the treatment area during and for 8 hours after treatment and ensure that junction boxes etc. are adequately protected against the ingress of the fluid. Remove or cover all food-stuff before application as well as fish tanks / bowls.

Do not apply to surfaces on which food is prepared or stored.

Where applicable, notify occupants of adjoining properties before treatments commence.

Display Safety Notices conspicuously during treatment and leave on site after treatment for at least 48 hours.

Preparation - Fungal Decay - Dry Rot / Wet Rot

Same as (Beetle Infestations) above plus - locate and rectify the source of dampness.

Cut out all structurally unsound timbers and make repairs isolating timbers where possible from damp masonry etc. and ensuring adequate ventilation.

For treatments of decayed timbers in-situ see ACS Ecobor 40 Paste.

Preparation - Organic Growth on Masonry

Remove any thick layers of organic growth with a suitable brush or scraper.

Some species of lichens are resistant to treatment due to their impervious surface. To optimise the effect of the biocide solution it is advisable to abrade the face of such growths prior to treatment (e.g. by wire brush).

Application Method on Timbers

Wear suitable protective clothing (coveralls), synthetic rubber/PVC gloves and face protection.

ACS Boracol 10 can be applied to timbers by brush or coarse spray.

During spray application some respiratory / face protection will normally be required.

Under normal circumstances one coat will be sufficient, however ensure that all accessible wood surfaces are thoroughly wetted out. Any surface which rapidly absorbs ACS Boracol 10 should be sprayed again at the time.

In the case of timber sub-floor areas, the base of the structural walls, sleeper walls and oversite (solum) should be treated with ACS Boracol 10.

Apply a second coat of ACS Boracol 10 after one to eight hours where there is severe fungal attack or the presence of House Longhorn beetle (Hylotropes Bajulus).

Provide adequate ventilation following treatments and maintain as long as possible after re-occupation.

Please note that any metallic surfaces (such as copper pipes) should be isolated from the treatment area as the boron salts may cause a chemical reaction causing surface pitting of the metal.

Application Method on Masonry

Apply ACS Boracol 10 under dry conditions using a coarse spray to saturate the surface. Allow to dry thoroughly and apply a second coat if required.

Apply to refusal as coverage will be governed by the porosity and type of substrate i.e. wood, brickwork, concrete.

ACS Boracol 10 is suitable for application on roofs, walls timbers, paths and patios.

Coverage

By Brush: 1 litre per 4m² to 8m² of timber surface.

By Spray: 1 litre per 4m² to 6m² of timber surface.

Finishing

As long as timbers are dry, re-occupation can take place 48 hours after treatments are completed.

Floor coverings should not be laid for at least 72 hours (or longer for certain impermeable or other floor materials, e.g. vinyls, foam-backed carpets etc.) In all cases, use lining papers to protect coverings from direct contact with timbers.

Treated timbers can be over coated when dry with a range of decorative / protective paints etc. (to ensure compatibility check a small area first).

Q) What is ACS Boracol 10?

A) ACS Boracol 10 is a professional-grade, boron-based wood preservative and biocidal treatment designed for the protection of timber and masonry surfaces. It is formulated to tackle threats such as woodworm, wood-rotting fungi, and organic growth, including algae, mould, moss, and lichen. It is effective for both interior and exterior applications, and its dual-action properties make it an ideal solution for comprehensive wood and masonry care. The active ingredients in ACS Boracol 10 penetrate deeply into timber, providing long-lasting protection against infestations and fungal decay while eradicating and inhibiting organic growth on masonry. Its low VOC content and non-flammable nature ensure safe and environmentally friendly use.

Q) How does ACS Boracol 10 work on woodworm and fungi?

A) ACS Boracol 10 contains boric acid, a powerful wood preservative that penetrates deep into the wood to disrupt the cellular activity of woodworm larvae and fungal organisms. For woodworm, it acts as a toxic barrier that prevents the larvae from feeding on the timber, halting their life cycle and ensuring long-term protection against further infestations. For fungi, including wet and dry rot, boric acid interferes with the growth and reproduction of fungal spores, effectively stopping the decay of timber. Its action is particularly valuable in damp environments where fungal decay is a significant risk, ensuring that wood remains structurally sound for years.

Q) Can ACS Boracol 10 be used on masonry?

A) Yes, ACS Boracol 10 is also highly effective on masonry and brickwork surfaces. It contains Benzalkonium Chloride, a surface biocide that eradicates and inhibits the growth of algae, mould, mosses, and lichen. These organisms can thrive in moist conditions and degrade masonry surfaces over time. ACS Boracol 10 not only cleans the surfaces but also prevents regrowth, preserving the aesthetic and structural integrity of walls, roofs, and paths. The product is especially useful in outdoor areas prone to moisture and organic buildup, such as patios, garden walls, and exterior façades.

Q) What are the typical applications of ACS Boracol 10?

A) ACS Boracol 10 is primarily used for wood preservation and the eradication of organic growth on masonry. Typical applications include treating timber against woodworm and wood-rotting fungi in both residential and commercial buildings, including basements, attics, and crawl spaces. It is also used on external wood surfaces like garden sheds and fences, as well as on masonry for the removal and prevention of algae, mould, moss, and lichen. Its versatility allows it to be used in restoration projects, where old, damp timber needs protection from further decay and pest infestations.

Q) What precautions should be taken before applying ACS Boracol 10?

A) Before applying ACS Boracol 10, ensure that the surfaces are clean and free from paint, varnish, or severe damage. For timber treatment, any insulation in roof spaces should be removed or covered, and electrical circuits in the treatment area should be isolated. It’s also important to cover foodstuffs, fish tanks, and any metallic surfaces, as the boron salts can cause chemical reactions with metals. For fungal decay, identify and rectify the source of dampness to prevent recurrence. Proper ventilation should be maintained during and after application to allow the treated surfaces to dry thoroughly.

Q) How should ACS Boracol 10 be applied on timber?

A) ACS Boracol 10 can be applied to timber using a brush or coarse spray. One coat is usually sufficient for most applications, but severely damaged or highly absorbent wood may require a second coat. The product should be applied until the wood is thoroughly wetted out, ensuring deep penetration into the timber. In areas prone to severe fungal decay or where House Longhorn beetles are present, a second coat should be applied after 1 to 8 hours. Adequate ventilation should be maintained during and after application to allow the product to dry completely before re-occupation or re-covering.

Q) How should ACS Boracol 10 be applied on masonry?

A) For masonry treatment, apply ACS Boracol 10 under dry conditions using a coarse spray to saturate the surface. The solution should be applied to refusal, meaning until the surface is no longer able to absorb any more product. The porosity and type of the substrate, whether wood, brickwork, or concrete, will determine the coverage rate. In some cases, a second coat may be required to ensure complete eradication of organic growth. Allow the treated surface to dry thoroughly between coats to maximise effectiveness. It’s ideal for use on roofs, walls, paths, and patios.

Q) What is the coverage rate of ACS Boracol 10?

A) The coverage rate of ACS Boracol 10 depends on the method of application and the porosity of the surface. When applied by brush, one litre will cover between 4 and 8 square metres of timber. If using a spray, the coverage is slightly less, at 4 to 6 square metres per litre of solution. Masonry surfaces may require different amounts based on their absorbency, but the general recommendation is to apply the product until saturation, ensuring full coverage for maximum protection against organic growth and fungal decay.

Q) Can ACS Boracol 10 be used in conjunction with other products?

A) Yes, ACS Boracol 10 can be used alongside ACS Ecobor 40 Paste for enhanced protection in severe fungal decay cases. The paste offers more intensive treatment, particularly for in-situ timber that cannot be easily replaced or exposed. The two products complement each other by providing both surface and deep-level protection against fungi and wood-boring insects. This combination is especially effective in restoration projects where wood has already suffered significant decay or in high-risk environments where moisture and fungal threats are persistent.

Q) What are the active ingredients in ACS Boracol 10?

A) The key active ingredients in ACS Boracol 10 are Boric Acid, Benzalkonium Chloride, and Monoethylene Glycol. Boric Acid provides long-lasting protection against woodworm and fungal decay by penetrating deep into the timber and disrupting the cellular processes of insects and fungi. Benzalkonium Chloride acts as a surface biocide, eradicating algae, mould, mosses, and lichen. Monoethylene Glycol improves the penetration of the active ingredients into the wood and prevents the solution from crystallising in cold environments, ensuring consistent performance in all conditions.

Q) How long does it take for ACS Boracol 10 to dry?

A) Drying times for ACS Boracol 10 depend on environmental conditions such as temperature and humidity. Typically, treated surfaces are dry to the touch within 24 to 48 hours after application. However, full drying may take longer in colder or more humid conditions. It is advisable to wait at least 48 hours before re-occupying treated areas and at least 72 hours before laying floor coverings. Adequate ventilation should be maintained during the drying period to facilitate faster drying and to ensure that the treatment fully penetrates the timber or masonry.
