Traditional Burnt Sand Mastic ( 10 Litre tub)

Price Per Tub / Burnt Sand Mastic & Oil- Driers (2 part) Supplied in two parts. Burnt Sand + Oil-Driers. Used to form joints between timber window and door frames and masonry or rendered masonry, traditional burnt sand mastic has been in use for at least 200 years. It hardens slowly but remains sufficiently flexible for the purpose. It adheres tenaciously to most surfaces. It is made by roasting sand on a hot plate or in a small kiln and was originally mixed with oils, lead based driers1 and crushed chalk. However for many years now, alternative natural driers have replaced the lead products. Mastic should not be over painted. Mastic fillets should be neat 20 – 25mm across the diagonal face, mastic should not be used to make up damaged arises or defective renders, these deficiencies should be repaired properly before mastic work commences. We supply stone repair materials and other lime products for repairing renders Details SKU SKU16321 Weight 12.00 kg Price: £18.99 (exc VAT) Options Qty 1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 27 28 29 30 31 32 33 34 35 36 37 38 39 40 41 42 43 44 45 46 47 48 49 50 Add to cart
