Sealants (VARNISH?)

BUILD UP THATCH & HOME in conjunction with Gripseal has determent that their non-toxic acrylic sealer is the ultimate product to be used on CCA poles. Gripseal sealants are absorbed by the pole and seal the pole surface from within, not merely a surface coating. The Imbuia sealer that is used by BUILD UP is stain resistant, non flammable and has a UV live span of 5years. Being a sealant it keeps in all the CCA and pole moisture, this limits warping and splitting of poles while still allowing the wood to breath.


reed1BUILD UP THATCH & HOME uses a combination of Cape reed (Thamnochortus species) and normal thatching grass (Hyparrhenia Hirta and Hyparrhenia Phillependula) in the thatching process. Grass bundles used have a diameter of 100mm to 125mm and have an average length of 1m.Thatching layers are 180 to 200mm comprising of 40 to 45 bundles per m²to a mass design of 90kg. A layer of 20mm to 30mm of Cape reed is used as the spray or ceiling layer. Cape reed is used to insure a smooth neat low dust retention ceiling. Cape reed is longer than grass and has no prominent leaves, rendering a tidy finish to the internal thatch. Cape reed is commonly used in Cape Dutch houses. Primary structures optimal pitch is 45°and secondary not to be less than 35°.
